my instructor when i was in school a few years back wouldnt use anything but diamont on his high end projects. i like it i just like to spray dupont, chromabase/clear on most vehicles but on my dads bel air we are finishing up diamont;) all the way baby. hahha but seriously its good stuff, in comparison with others i like it....if youve ever seen a red car that looks almost like youve got a fountain running over it its so wet.
