I have a ’76 Chevy Cosworth Vega that I am going to repaint with Eastwood Euro Racing Green paint and Eastwood Clear Coat. The original paint is faded with scratches and some dings, but overall is in good shape. Other than some small surface spots the car is rust free. I plan to sand the small dents and dings down to bare metal so I can fill them but the rest of the paint on the car will be sanded and primed. Should I use Eastwood’s epoxy primer or 2K primer after I sand those dings and dents down to bare metal but before I fill them? After they are filled, do I use the 2K primer?
