Hey guys. I already got me a gallon of nason fulpoxy primer with activator ordered and i had planned on using it on the out side of the car and was wondering what you guys thought of the summit racing epoxy primer Summit Racing SUM-UP230 - Summit Racing Equipment® Epoxy Primer - Overview - SummitRacing.com I don't particularily want to use it for the exterior in fact i really don't but what about the insides of the car such as floor pans undercarrage inner fenders engine bay and anything else that doesn't have to be real perfect (maybe not the engine bay). Its only about $80 with the activator. Whats your guys opnion on using it for the hidden places which may or may not be topcoated? worthwhile? or should i just get another gallon of nason?
