Pits in hood. How do I fix them??

Sand off all paint on the metal you are working on and prime. Next use you iceing and fill the pits using a plastic spreader. Thin is better. Wait for it to dry and block sand. Buy a rubber block sander and some 320 wet or dry sand paper. Sand the iceing using plenty of water. Repeat iceing if neccessary. Next Prime 3 or 4 coats. Get some Black primer in a can while you are at the store. Put a very light coat of black over your lighter primer. After it drys wet sand the darker primer off being careful not get into the iceing. You will be able to see dark spots if you have more pits and need more iceing or primer.

Prime again. Make sure ALL bare metal is covered with primer before you paint. Last primer coat should be sanded with 400 wet sandpaper. Paint with automotive grade paint. Not a spray bomb from Walmart!!!! You paint will look great and last for many years.

I bought a random orbital sander which made all the difference in the sanding.

The final result was at least as good as new
