Status: offline 		Pretty pleased with my third go around at using latex paint, that I had to share it with you all.

The subject (aka guinnea pig) is a Yellow Aircraft Spit Mk14. Paints were mixed by my local hard ware store, whilst I shopped for gardening supplies, with the aid of the M.M. chip sheet from Frank Tiano. The experts there said they were able to get the color to within .05 of a percent. (beats me) but when I put the chip against a painted portion of the plane, it wonderfully blends right in.

Here is/was the test, on my p40 I used water to thin the paint, in order to get it to come through the gun....worked to get the paint out of the gun just fine, but water takes to long to dry, and runs very very easily. Yes I could have used less water, but the point where the paint shot without retriction wasnt until it got pretty runny. I finished off the Warhawk by using a medium sized paint gun, and very high air pressure. Made for a friggin foggy mess. This time I started experimenting with a few solvents and thinners that I had in the shop....I am not gonna share the failures, but I will tell you what worked very well for me.... Isopropyl rubbing alcohol. Thinned the paint, flowed well through the gun, sat on vertical services (as long as I didnt sit too long) and dried to the touch in 2 hours, and I was able to paper towel buff it down in 3 hours, I appled second coats the next day.

I was worried about the alcohol when I read in previous post that the alcoholl had removed the paint, but it seemed to work well for me in this application. "knock on wood"

Can you share a little of the paper towl buffing details with us. I have not used that technique before. I have painted a few birds with the latex/water thinned at 10 to 15%. Works great and best of all, it's cheap.

Status: offline 		Just curious ray, why didn't you use the Windshield Washer fluid to thin (it has Isopropol alcohol in it as anti-freeze) and the FLOTROL (one capfull per quart)?

The winshield washer fluid not only acts to thin the paint, but also delays the drying time.....This allows the paint to level off on the surface. This is particulary important if you're using a gloss or semi-gloss, and less important if you're looking to spray flat colors.

I've been using latex for a couple of years now and rarely have had any run problems.

I do have to use an automotive type spray gun, gravity feed type, at 50~60 psi...

What brand of latex did you use. Did you do a gas test yet to see if it will soften the paint? The Behr brand is what I used and had problems with denatured alcohol removing the paint and gas making the paint soften. I had to repaint the fuse and then clear coat with Nelson Hobby flat clear. I am looking to try a different brand on the Hellcat that I am building.

Status: offline 		Who would da thunk, house paint would generate so much interest.... not me... I feel silly now for all those years of calling it bad names. In all honesty though, money no object, I prefer the automotive paints. Just alot easier to shoot. That being said, I dont have any excuses for not ever having scale colours on any airplane due to money.

Todd, I always get caught up in the project I am working on, plus I always have a couple of Wings tapes going in the background. I am looking forward to starting the detailing in another day or two, weather pending.


Carey, always good to hear from you my friend.... On the buffing, I have to confess that I got the "technique" from a friend of mine, Mr Brit scale, Pete Fowler. Pete's painting and detailing talents are above compare. In a few sessions when I watched him at work, I noticed this was something that he did, funny thing though is I never asked him why, I just picked it up. What I do notice is that with some flats and semis, there maybe a loose layer that can be wiped down, than collect finger prints, or smear onto other things, so its like a color sanding buffing if you will, in my opinion. Now the crazy part could be that on the days I saw Pete working, that he only did it to see if I would go home and pick it up....... as he chuckles lightly to him...."Ray is so gullable"..

"Branded"....(sounds like a signature to me Sir) I am still relatively new to painting with house paints. As I was doing all my tests, I think the one thing I didnt have was windshield washer fluid. Though I did try a few other things....... one thing I wanted to do was be able to replicate as close as possible the drying that I am used to when exposed to automotive paints. I spray with low material ratio, so it can mist well without running and get into the panel lines well without filling em up. I am really satisfied with using just the straght alcohol, to the point I was almost waiting for something to fail in the procedure...... I commend you on being able to apply the stuff with out running. It was a challenge for me.

Kirk..first off, I saw your Jug that you sold, soon I hope to be flying formations with the new owner, great looking job you did on it.
The paint is Fuller O'Brien Liquid Glo, acrylic latex semi-gloss enamel.

I painted a wood tray with it, and I plan to do a gasoline test with it in a day or two. If not I will be asking here to find out what does and doesnt work with this paint to make it gas proof.

Ray

Status: offline 		Well, the reason I mentioned Windshield Washer Fluid is that it's recommended by Roy Vailaincort in an article he wrote about painting uisng latex house paints.

The article is probably a couple years old, but I've been following his advice for a couple of years now and am quite satistfied with my results.....

I use the Windshield Washer fluid, in conjunction with the product "Flotrol" and have been very satisfied with the results....

Here's a picture of a Ziroli Corsair wing panel that I just painted with BEHR latex, the color matched by HOME DEPOT.....

I've never experienced any problem with BEHR paint as has been previously described...Perhaps it's just my good luck, or not...Who knows....

Anyway, I hope the photo shows the detail in the wing, as well as the semigloss surface....The wing is three piece so you won't see the outer panels.....

The airplane will have a Zenoah GT80 with CH ignition....

Enjoy!

Do you use the flat or semi-gloss Behr paint? I used the flat and had the problem with gas making it turn gummy. One other gentlemen here on RCU had the same problem with the flat. Maybe the problem is with the flat paint and not the gloss or semi-gloss.

Status: offline 		K_Sonn...It could be there's a problem...
My Ziroli P40 is painted with BEHR flat drab green.....I don't see any problems in the vicinity of the fuel fittings.
I'm not saying there isn't a problem, I'm just saying I haven't experienced one YET.....

GrnBrt....Flotrol is a product that prevents fisheyes in the paint, and also acts as a lubricant for spray equipment when using Latex Paint....

You can buy Flotrol at the HOME DEPOT and also I've seen it sold in other smaller Paint Stores that sell House paint.

Status: offline 		Thanks much, just didn't know it by that name as it's called something different in the auto body shops, just plain old fish eye remover. I have been out of scale for over 7 years and plan on getting back in it next year with a Skyraider and feel that any scale plane covered in plastic is almost criminal! Latex paint sounds perfect and will have to use nelson clear coat for fuel proofing as I will be using nitro engines, not gassers. Well I do have a 1/4 L-4 that will get a gas engine, but that's down the road a bit. Thanks again and keep it coming.

Status: offline 		I just finished painting this Corsair with Behr satin latex. I thinned with water and used an Iwata Eclipse airbrush. The markings are also done with latex. The advantage to the latex is that I could do this in the basement without fuming up the whole house with solvents. I will put on a clearcoat of oil-based Minwax next Spring when I can do it outside. I don't mind th slight yellowing of the Minwax.

One interesting note: The guy in the paint department said that flat latexes are completely different than satins or glosses and they don't hold up as well as flats. He was referring to walls but it's something to think about.
