I am ready to paint my new GWS Corsair and all the spraybombs I have tried melt the foam. What kind of paint can I get in small portions to do the job?
Also has anyone tried the Testors air brush kit with the canned air?

Use acrylic paints from a hobby/craft store.

Water based craft paints. Walmart sells a lot of colors in bottles that are around 8 ounces. Inexpensive at under $2 each.

I painted a Simple 400 wing and it only took an ounce or so, and covers quite well. It will brush on and look fairly good, but you're adding more weight with a brush; if you have an airbrush, this stuff could be thinned and sprayed on for very little weight gain.
Dennis-

My son uses that stuff. I thought about it but when the humididty is high it seems the paint wants to weep a little. I don't mind using it but I think I would need to seal it with something.

Use Latex house paint. It can be mixed to any color you want and doesn't cost much.
