I have posted before of a local guy who always tells me different things and says what I am doing are wrong, Well yesterday after I had sprayed epoxy over a 1986 Monte Carlo I am doing for a friend he says why are you using epoxy and 2k? I told him I was taught to use epoxy to seal everything then go on with body work and 2k, He said all you need is DTM primer for all your needs. Well here I am again, I want to ask you guys because I don't know a lot about this DTM he is talking about. I'm not going to switch what I been doing just want your guys opinion.
