I am coating all my foam planes with Polycrylic. I am using gloss or satin, depending on the plane. You must rub down the plane, VERY WELL, with 91% rubbing alcohol first to break down the surface tension. A foam brush works very well. It levels out nicely. Don't over work it and don't apply it too thickly! Check the light reflection for missed spots. If you find that there is still a surface tension problem, you may apply a very thin coat of Polycrylic and then rub it dry with a paper towel. Then it goes on smoothly. Allow it to dry completely before adding coats. This not only improves the appearance of your plane but also cuts down on air resistance. This also makes a very nice primer for spray painting. It protects the foam from melting and spray paint adheres to it. As always, practice on scraps or an old wrecked plane first! The Doctor ADDENDUM. Use VARATHANE waterbase polyurethane instead of Minwax. It is MUCH better quality. Sorry, guys. I just learned this. The Doctor

Re: Minwax Polycrylic
Airbrushing will give you a much better finish, but you also have to do a lot of masking. Polycrylic gos on so well with a foam brush, it's worth it to avoid the masking. I always say.... "It looks good from afar, but it's far from good" Oh yeah, polycrylic is available in spray cans. I haven't tried it. The propellants might melt foam. The Doctor

I have used the Minwax polycrylic on 3 of my planes as well, this product makes it easy to keep your planes clean

Re: Minwax Polycrylic
I have been doing this lately. Using semi-gloss out of the can with a foam brush. Yes I go over the decals after rubbing them down good to make sure they are stuck down well. I think it helps seal the edges down and gives a uniform sheen between paint, plastic, and decals.

Re: Minwax Polycrylic
Greetings gang,
When applying the minwax product, has anyone noticed any coloration change over time? especially on white EPO models?
I have tried similar clear coating techniques to rocket surfaces (not foam of course) but noticed that in time it took on a slight yellowing. Just curious.

Re: Minwax Polycrylic
I have coated my airplanes with Minwax, they look great!! The Mustang was easy as its already painted so a couple of coats just made everything stand out so much better. Looks like she just got a wax job. The decals stand out beautifully. The Pandoras(s) and the Cub took a little work with IPA, and I gave them three coats, using a foam brush. They turned out great as well. Take the time to really go over the surfaces with IPA, I could have done a better job there, but by the third coat, it covered nicely. Short drying time is nice, although I let mine set over night.Team Gross!

Re: Minwax Polycrylic
Greetings Grossman,
Holy Cow!!! I thought I could see clouds reflected on your wings!!
Buddy, that looks outstanding!!!
I'm curious to see if you notice any difference in the flying characteristics of such an obvious low resistance surface area. Let me know will you?
