I got off to an early start, first came hanging plastic over the framed in door way, then sealing a box fan in the end window. With the A/C fan running the two vents in this room, along with the box fan, keep the fumes out very well. Next up was to clean and wipe the metal parts with Prep All, then they got primed. I have to run out and get some tack rags, forgot to get them on the way up yesterday, and will continue with the painting. I am not in any hurry, my goal is only to get the polybrush and polyspray on today, so there is plenty of time.

Tack rags have been purchased. For those that have not done any painting it is of utmost importance to be as clean/dust free as possible, for every spec that hits the airframe will show up in the finished surface. I know mine will likely will not be spot free but it will be a whole lot better than if no thought as to dust was given. That said, the room has been vac'ed again and everything wiped down with the T rag. I will catch my breath and then proceed.

OOPS! I missed something somewhere. Years ago I took a Bud Nosen Citabria kit (100+ inches) and made the wing semi symmetrical and extended the nose a little to make it into a Decathelon.. It was covered and painted using poly tack and poly tone. I do not recall 'poly spray', so what is it please.

A second coat of Poly brush is done. I am going to do one more to get a really slick surface, remember it's a hot rod. After the third coat I will try and get a pic showing the surface.

The third coat is done. Getting a nice sheen to it, this means the weave is filled in. I'll take a break and then shoot the two coats of Poly spray. Depending on the finish at that point I may wet sand it, I hope it won't be needed, we'll see.

After looking everything over real well, it looks great but I felt like it needed one more coat. I could still just slightly tell a difference between the coat on the tapes and the open areas, it just was not quite the same yet, close though. Anyway I gave it another coat, and oh what a difference it made. Here is a side by side of the 3rd coat and the 4th coat.

Remember how we talk of being too anal, well apparently not enough. After that last post, and a half hour break, I went in to get set up to spray the Poly spray (the silver colored stuff) and I be damn if I did not notice something. At the trailing edge of the fuse, the fin post, I did not put pink tape up it. Not having any with me and the fact that to get one to blend in now it mush be really thin, I went and got some really thin medical paper tape. And I am currently cutting pinking out of the edge with an exacto, at 17 inches long per side, a pink every 1/8", it really puts a hurtin on the fingers. I'll show it when I am done.

Thanks Buddy, but, I just finished the cutting and applied them. I am pooped, so I will take the airbrush with the Poly brush and blend them in in the morning. This paper is so thin it won't take much to get it done.

Thanks Vincent. Believe it or not I have spent the past four hours putting all the metal pieces on the airframe, mounted the fuse on the stand, vac'ed the room, and wiped everything down with the tack rag. I am taking about a 30 minute break and then I will begin spraying.

I've seen that set up, (fan in the window) cause an explosion before at my friends home. Just a word of caution.
The way a safe setup is accomplished in a spray booth is the fan blades are turned by a belt from the motor that is outside of the spray room. The blades are in a duct sucking the air out. Even the light fixtures are outside the spray room or booth. They are behind glass panels that are sealed air tight from the spray area so the fumes cannot be ignited by a spark!
Spark from electrical motor of fan plus fumes of paint if just the right mix with the air go boom! My friend blew the roof and front wall of his house off 75' across the street and he hard burns all over his body. I know he was lucky to survive. It scared me because I also was painting in a make shift spray booth. I had created a spray area with plastic sheeting which is another No No. This is because of the static electrical spark igniting the fumes. But that's another story. My friend had been spraying many years like that until that perfect balance of air and fumes ignited and ruined his day. Something to think about my fellow modelers!
I have also seen it happen to a second friend that was spraying in his garage with the garage door open and the pilot light on his water heater ignited the fumes and boom! He was also burned over 80% of his body! I saw him a year later.... he was 6'4" but now is about 6 inches shorter after all the tendons contracted from the fire and his skin, well what's left of it...let me just say it's disturbing to look at.
I really didn't want to write this but my friends wanted me to warn everyone so what happened to them would not happen to anyone else.
On a happier note... Great job on the Pitts!.. Robert.

Thanks Don and I appreciate your concern. I also have the two A/C vents blowing into the room, the fan just helps direct the flow. I sprayed some (at the beginning) MEK through the gun and the airflow pulling it outside was superb, no build up. The fumes are so minor I don't need a respirator, but am wearing it anyway. The wife is super sensitive to these smells so if I wanted to continue working when she gets here Tuesday I had to make sure there was no lingering odor/ fumes.
I have primed the cabanes, after removal, and have touched up the paper pinks. Have to make some Tea and then I will start shooting the silver.

Woo Hoo, the silver has been done! I am officially caught up to the point I was a few months ago. The silver was one good and wet coat, I will let it air out for a couple hours then possibly do some wet sanding, haven't decided on it yet though.
