Title: 455olds heads
Post by: Garysxx on July 08, 2023, 08:16:50 PM

Heads pink, turning brown exterior on a new engine around my exhaust ports, the paint was gray now it?s brown. How do I prevent this from continuing? Motors freshly rebuilt.

Same thing happened on mine after about a year, and I prepped and coated the mother loving shit out of it.

try finding your color paint in the 1200 degree paint instead of the 500 degree paint
