Powder coating is the way to go for sure. I decided to repaint my valve cover, and I did an immaculate job. Sandblasted the surface, prepped it with TSP, put 6 coats of primer and 3 coats of engine paint. I waited for the perfect ambient temperature and humidity.

One year later, it's starting to bubble up again. Aaaaargh! Wish I had powder coated it!
