hey guys, i am wirebrushing and painting my frame on my 71 chevelle. my uncle brought me this 2 part 4:1 epoxy primer called interplus 356, made by International Protective Coatings, that he uses at work (he's a painter) i looked up the data sheet and the performance data and it seems to be good for my application. if i had no epoxy primer yet id go with a PPG epoxy but since i've got this stuff i dont want to throw it away if i could use it. i'd like to topcoat it with por15 chassis black which i THINK is a urethane coating. i'd greatly appreciate it if you guys can take a minute to look at the data sheets and give me some input, as i have no idea what the performance data means. thanks a lot
