Never use varsol near primer , use the paint thinner as the car should allready be clean from the many times you have allready sanded it down , the so called TAC rag works good as well. As for the paint you should use the 2 part paint . It is the paint then the clear coat after , this way it is alot easier to clean up any clear coat runs with a razor blade , did my limosine in white and that coulor is almost as hard to paint as red .
