I am a bit confused now, so I should not glass it and just use primer + Sanding + FM??? cause I was using primer on the glassing then FM.. Sorry guys for being ignorant, just bear with me a little longer.
Once again thanks for responding.
Glassing with Polycryllic is done for paint preperation. The polycryllic is not as hard as an epoxy. For paint, it doesn't need to be. I used this process on my Ziroli Stuka .
You are looking to use a metal foil. The burnishing process would damage the "soft" poly surface. Epoxy or polyester are far more suitable for your purpose.
I doubt that you would be satisfied with just paint and primer. (omitting the glassing process) The wood substrate is far too soft to withstand burnishing. For paint, alone, I've seen some try to seal the balsa and paint, without glassing. 99% of the time, the wood grain is visable. Besides denting and marring the balsa, wood grain would be evident through the FM.
