Hi guys, bit late on this one, I used VHT paint on my engine parts, sprayed them, let them dry overnight and then baked them in the oven, however for 40 years I've worked with centrigrade, the instructions were for Farenheit, so the silver turned yellow. Then I just oversprayed them and left them well alone ! They have turned out great, the other parts that I baked for the correct time and temperature came out OK as well.
Cheers
