Well, I wanted to take a stab at some DIY painting to see if I could get the knack for it. I decided to paint a few engine bay related parts first because they won't be heavily scrutinized. I first sandblasted everything down to bare metal. Some of these parts had 1/16th of an inch of white paint on them from the previous owner's ghetto paint job. I then coated the bare metal with POR15. Then when the POR15 was slightly tacky (3 - 5 hours later), I primed the parts with a few thin coats of a Zinc Chromate primer (good adhesion and corrosion resistance properties). And about 8 - 12 hours later, I sprayed the acrylic urethane enamel Vogue Silver Metallic on the parts in several thin coats.
Although the parts came out pretty good, I have come to the conclusion that the engine bay is as far as I want to challenge myself with any kind of automotive painting....especially with a high density metallic flake paint like Vogue Silver Metallic. It is far too difficult for a novice to lay down a consistent metallic pattern, and any slight imperfections are highlighted even more by the distortions it causes in the metallic patterns. For any "A" surface painting (exterior clear coated surfaces), I'm going to leave it to the professionals.
