Thanks for all the info, you sure do know paint. This is my first attempt on painting and I am gaining experience.
Klass Kote has confirmed that the paint is bad, nothing I am doing is cousing the paint to float. They recommended the paint be shaken. So I shaked it. When I mixed the catulyst and the reducer I use a paint mixer on my drill.
The first batch was mixed the same way as the second batch today, one was orenge and the other yellow, no mater how much I mixed or stirred. Random weirdness, just glad the yellow is done.

Do I understand properly ?
Hi Tony,
I am somewhat confused.
It appears to me that you painted the wing with the orangy hue and after you painted over the orange with the yellow.
Concerning the mixing and the explanation that shaking does not necessarily get the pigments that have settled at the bottom to become distributed evenly ( homogeneity ) You mentioned that you used a paint mixer on your drill. I would think that this would create the homogeneity and the results would be the proper hue of the paint composition.
I can only conclude that the pigments quantities ( proportions ) were not consistent; were different.
A very small pigment quantity variation would change a yellow perception to an orangy.
I am glad you got things to your satisfaction and a consistent hue.
A useless link for Tony's situation but interesting for knowledge.

Zor, I know this is all confusing.
What I did was take the half pint (8oz) and shook the hell out of it for 10 min as recommended by KK, then I mixed the paint with a small dowel being it is a small can and the opening is to small for anything ells. Then I drained all of the paint into a mixing cup. 8oz of paint went into the cup, then I added 8oz of catalyst and mixed it with a paint mixer on my drill, and I mixed with a paint stick too. I let it cook for 40min then added the reducer and mixed with the same mixer on my drill. I tested the paint once I mixed the catalyst in and I would come back every few min and stir the paint. By the time it was ready for the reducer it was orange as I tested it again with a paint brush on a previously yellow painted part.
I knew it was not a match and painted some small parts just to have a reference, not the wing. I then brought the center section of the elevator and placed it agents the fuselage. It was orange. So I mixed up the last of my paint from a pint that had mixed results of yellow and orange batches.
I did the same procedure, shook the hell out of it, mixed it with the drill, tested it and once it had inducted it was still yellow so I added the reducer and it still was yellow so I painted the wing and parts. On the orange parts I painted earlier as a reference I could tell right away it was the right yellow.
This all really has nothing to do with what or how you mix it, it is a bad batch as confirmed from KK and the results are random. One time I get yellow, the next orange. This paint is not that hard to use and if there paint was this difficult they would be out of busyness, just dumb luck I got a bad batch of paint, 2-1/2 pints of bad paint.
Hope that clears things up for you. The pics only show the yellow paint on the wing and parts, its the light that plays tricks on your eyes

I haven't looked at the wing yet, it is locked up in my trailer till tomorrow. I will paint the black lettering stencils tomorrow morning. RCAF 671 on the fuselage, 671 on the tail and the cowl. The wing gets RCAF on the bottom of the wing on each side. Then all that is left is the roundels on the top of the wing and on the fuselage between the RCAF and the 671. This will complete the painting.

An experiment about color rendition
Hello Tony and All,
You may be interested in this experiment.
It is aimed at trying to show you what I see on my monitor and perhaps what many others are tyically seeing.
I photographed my monitor picture using my Kodak Z612 camera and prevented the flash from actuating ( NO flash ).
I uploaded the picture to my computer and now I am attaching that pic to this posting.
We can notice the big difference in the yellow color rendition.
As I look at the picture stored in my computer the yellows are a bit darker but the difference in hue is obvious and reasonably accurate.
I now know how to remove pics if you wish me to do so.

Today I will be painting the black littering using the getStenciels vinyl paint mask. They go on pretty strait forward and they lay over panel lines and rivets well.
I will shoot the black and let that set up, then remove the stencils.
I placed the roundel so I could get proper placement. I will shoot the white once I pull the black stencil.
Then once that sets up the red maple leaf followed by the blue ring.
I will do this all with my airbrush.
I will hit the stencils first with the KK clear to seal the mask.

Got a quick look at the wing, looks great. It has the finish I want on Angie. The only problem is the finish on the fuselage is not as good as the elevator, ruder and wing so it looks just a little off but who's looking?
I am getting ready to shoot the clear and then the black. I ordered 4 stencils of the RCAF but can only find three so I will not do the bottom of the wing, might do something ells.
Here we go!

Clear is on and I took some pics to document and discovered I had covered the 1 on the left side of the 671 so that 1 wont have clear on it and I guess I can see if it really makes a difference. Glade I caught it.
The black is cooking, will shoot that in a few.

Thanks OKC,
The black is all shoot.
I started with a light mist, this air brush is awesome.
I would go darker little by little
Heavier as I went on.
Then the wet coats.
We will see soon how I did.
I have the large roundels on the top of the wing and I hit the mask with clear. White is cooking and I will peal the black mask off shortly.

Tony the problems you have had are surely no laughing matter but there is some humor in all of this viewing it from a distance, for an example. You remind me of a cat that has a mouse cornered but hasn't quite figured out how to catch him, the cat knows he is in that hole and lurkes around wondering where hes going to come out next, he is very determined to get that mouse and is funny to watch him work his plan, ha ha, it's a riot to watch, down right funny.
Thats you Tony, you never give up, no hill is to high to get over. You plug along and overcome every obstruction in your way with such ease and maintain you sanity while others might have burned it by now. I have never seen a better example of , if there is a will, there is a way that you have shown us all watching you work. In spite of it all your going to have an incredable airplane and taught us alot in the process, Thank you for that, I love it, truely great stuff.

I pealed the vinyl stencils off, they came off very easy, no residue.
The lines came out very crisp, no bleed threw.
Even the 1 on the left side that did not get clear coat first came out great.
I am getting ready to shoot the red over the white on the roundels.

The good, the bad and the ugly!
Ok lets start with the good!
The wing came out really nice, only blemish is a tinny spot on the top tip where some plastic hit the wing when I was just finishing painting.
I had just cleaned up and I was baby sitting the wing because the wind had picked up.
Well it did not take but a second wham, a piece of the plastic hit the wing.
No biggy, weathering.......
The stitching came ourt really good and I am very pleased with it.
The bottom came out really nice. I haven't fitted the hatches yet but they will be fine.
Ok so for the bad....on the roundels the vinyl mask left me a gift...the glue
The maple leaf came out good but the vinyl stencil left some glue on the white.
And the first stencil on the yellow left glue too.
I thought at first that the white not being cured was the reason but the yellow cooked in my trailer for 24hr before I put the white on, even longer being I did not shoot the white till noon.
Only on the fuselage the black lettering stencils came off clean. The fuselage is totally cured.
So there is a catch 22, you are suppose to put stencil #1 on and paint, then stencil # 2 on, then paint, then the finale stencil and paint. But you are suppose to remove the stencil before the paint cures (24hr).
I took a chance and only waited a couple of hours before I went with the second color, the paint did not pull but this paint does not like any tape before it has completely cured.
The white mask line was not that great but it gets covered in blue.
You can see the line from the vinyl stencil.
The ugly is the fuselage roundels. The mask over the white left gobs of glue on it, wont even take a pic of that..........
So I am not going to panic (or chase the mouse). acetone will take the glue off, but it may dull the paint. I am thinking I will clean all the glue off and then if it is dull I can hit it with clear to shine it up again.
Is this entertaining enough Leroy?
Tomorrow I will shoot the blue and call it done.

So acetone did the trick with no harm to the paint at all
I got 90% of the glue off, ran out of acetone so I will hit HD this morning for more.
My next hurdle is aligning the last paint mask, being I removed the first one I have no reference.
I will have to free hand the last ring.
The red I used was for the P-47 Angie, it is more maroon then red, par for the course
I have the blue that I got for Angie to do the stars and bars, hope that is not purple!
I can see the summit of this mountain

I cannot refer to you as TB _ _ _ I would feel I am being impolite.
So, to me, you are Tony as the use of Mr. is not usual practice in these forums.
You can now see the peak of the mountain and it makes me wonder what your total cost of this model happens to be; just thinking.
There are some different results in your model than I am used to but we build for different purposes.
I am not and never was a "detail builder'. I have great admiration for your work and the high level of patience and attention to details that you have.
I am happy to see that you have finally solved the color hue problem that came up. The 'orange peel" finish is not noticeable at a distance. It just reminds me of the finish on automobiles and trucks before the change to acrylic finsih in the 1970s or early 1980s.
I do not know for sure what kind of paint finish the full size Canadian Chipmunks used.
I suspect it was aircraft dope. If anyone knows it would be nice to read them.
We, as flying instructors, were not concerned with that at that time since our planes were not painted yellow. They were aluminum color.
Again, I remain with lots of admiration for your nice work and look forward to complelely asssembled pictures.

On the bench for today will be to paint the blue on the roundels, this will be the last paint hurdle.
I am gluing in the flap hinges now. I glue in the hinge first on the flap then I glue it into the wing. I want the hinge to be at a uniform depth so this works best.
Maybe even start the dry ink transfers.

Thanks Zor, I do need a plane to have as much ground appeal as it does air appeal. even if I am the only one at the field, taxing out, takeoffs, and landings are the most enjoyable for me so a plane has to have that appeal, canopy opening as you land, and taxi in and out. Adding a camera also adds flight appeal. I have found that just flying alone does not excite me in this hobby. Building and flying, with the added enjoyment of all the tricks I build in do it. I try to build a strong reliable plane that mimics the full scale as much as I can. This is my first attempt at finishing so I am catching up and this plane has served well as a learning platform. When I get to Angie I will have a lot more knowledge in the finishing proses.
This plane will get a lot of flying use and will be my go to plane, it will handle 20mph winds, cross wind and even calm winds. A cold front just came threw with temps in the 70s for the high. By the time I maiden hopefully next week the temps should be good for test flights, not in the 100s.
Final assembly will take place next week with field setup and run up tests during the week setting up a maiden for the weekend providing I can get everything working, mainly my telemetry. The main telemetry I want is air speed indication (pitot tube) RPM, and engine head temp, the rest like receiver voltage can wait and is not as important as the rest.

So I did not put to much thought into the roundel colors. I had a red, whit and a blue for Angie so I thought I would just use them.
The white was good, insignia white for invasion strips and the stars and bars.
The red I got was insignia red #45
this is what I used on the roundel maple leaf.
It is nothing like this color swatch PC monitor or not.
Here is the RAF roundel color red, actually looks darker then what I had.
The blue I have is the insignia blue #47
The RAF roundel color is more subdue.
I wont know until I mix it and I don't think the red was a mixing issue, I mixed it well, just a hue issue when one is ordering based on the color they see.
For Angie I will take better care to select the correct colors.

So the last roundel mask went on as I thought, free and was the best way to do this.
The only thing I do not like about the way they make these is that the first mask circle and the last mask circle are identical, leaving the last mask to lay right on the first line. This will result in a small white line around the blue. The correct way this mask should be done is to have the last roundel mast just big enough to go around the first mask paint like, maybe 1/64"
This would insure you cover the first color completely. Yes the line will be bigger but that is better then have the white showing.
So on the wing roundel I started with the mask pealed off half way and cut, then I placed the top on the outside of the paint, not on top as they have it.
Then laid it down. at the bottom it laid on top of the whit so I cut it back with a #11 blade.
I would rather have a uneven line then have white showing.
The clear is cooking and I will shoot that now.
The fuselage roundel is lays as they intend you to do so we will see how that works.
