Hi - I just bought some Z Poxy finishing resin to use on a guitar and I read on the back of the box that you must prime before painting. I'm fine with priming - but then I did some searches and found out that some epoxy finishes (not that this is supposed to be a finish) will leave a waxy residue upon curing and that it is referred to as amine blush. You are supposed to wash this wax off with water and an abrasive (scotch pad or something). You should never use a solvent as it will spread the wax into the pores and make it impossible to remove. The importance of removing this amine blush is that because of the waxy nature of it, it makes paint adhesion difficult or impossible. SO - my question is - has anyone used Z-Poxy finishing resin and what special steps do you take prior to painting?
