Title: Paint under Monokote
Post by: Motorman on December 10, 2016, 09:21:36 PM
Has anyone got experience painting the bare frame before using some kind of transparent film covering? I've got transparent yellow and was thinking it would look better if I used some light gray or something to blank out the wood grain. Right now it's got a very light coat of Balsa Rite film glue thinned 50/50 on it. 

Thanks,
MM

  You should have thought of that before you put the balsa rite on it, especially thinned like that. It's a heat activated adhesive. If you get paint to cover it, it will probably blister when you heat the film. And thinned out it has soaked in pretty deep, so you can't sand it off. Just cover with opaque film and move on.

MM,
You might go to a auto body paint story and get some pigment for lacquer, mix in a touch with a small test of the 50/50 thinned Balsarite and put it on a piece of crap to see if it dries. If it works do the bottom of the stab and then MonoKots (or whatever film you use) over it. Use low heat setting on an iron (don't use a heat gun) to avoid the bubbles that Dan mentioned. I have used two coats of Balsarite under MonoKote with no problems as long as I went slow with the heat.

Best,    DennisT

I'm pretty sure you meant scrap.

Take a look at this thread, near the bottom.  Bob Branch painted his balsa/carbon fiber profile with plain old rustoleum then 'coted over it.  It turned out very neat with a different look.

I've done 'coat over Rustoleum; UltraCoat and old Monocoat works fine, the new Monocoat needs such a high temperature to shrink that the paint bubbles underneath the film.
