Wrinkle Paint for Valve Covers

Krylon use to have a really nice wrinkle paint, but for some reason they discontinued it. I now use VHT.
It works really well. Read the instructions for best results.
Warm temps always help. If it doesn't wrinkle up to your liking, a second thicker coat is the ticket. I have also used a heat gun to help in the process. Harbor Freight has an inexpensive heat gun that works just fine.
