How hard would it be to do this?
Her’s my idea:
Coat the valve cover white (as a base). Using a piece of card board/poster board, make a swirl pattern to lay down and drop the colors. Spinning the template slowly after each color.
Then, I’ll take a tooth pic or maybe small brush and sweep the colors together here and there. When I’m happy with it, I’ll toss it in the oven.
What do you think?
