Will polyester resin adhere to marine ply?
Do I need to do any prep to the ply before matting it over with polyester resin?
I was going to first give the ply a coat of resin mixed with some acetone to help it soak into the ply before matting over.


Resin bonds to ply by soaking into the surface and setting. This is an OK bond but it can be improved further by using a PU like G4 primer sealer.
