I'm looking at the z-rust product, does it need to be topcoated like the por??? Z or P i'm planning to use it on the frame, top and bottom floor and trunk pans, firewall....I like the fact that the zero rust is easily repaired, and requires less in the way of prep (although i'm media blasting the whole car). One ? in particular, what have y'all done in the trunk??? Have you shot it with the "crystal clear" or the por topcoat then spatter paint and clear, or spatter then clear??
thanks
