You are gonna want to remove all the clear coat from the car. Go with a 220 grit to a 400 grit to a 600 grit and since it's a Corvette even a 1000 grit WET sand paper. With primer you are going to want to chose the color that is closest to the color you paint the car.

Get 80 grit paper to start and 120 grit to finish with. You also need a long sanding block (for the 120 grit) from an auto supply store or even Walmart. Buy good quality auto primer and Paint from a reputable online or regular paint store (Sherman Williams). Match as close to a factory color as you can.

For bare metal use an epoxy primer,then final primer. 60/100 grit-body filler, wet sand -400-600 and 1200 to 1500 for final sanding prior to buffing
