...here is a link to the
manufacturer's data sheet for Spraymax Clear Glamour.
Substrate: Solvent and waterborne base coat systems, old paint coats dried according to manufacturer's instructions (cleaned and sanded).
I have pretty much taken this as a carte blanche for experimentation, and have, thus far, not been disappointed. I'm familiar enough with a couple of different paint systems to know that you will get a more cohesive overall finish staying within some reasonable recoat windows. As already stated, I find the application of vinyl graphics to be a limitation in this regard. I might be more relaxed about this because I'm only doing it for myself, and I won't complain.
