    I sand blasted my manifolds to grey metal clean, not a spec of rust, and painted with the Hi Temp Grey paint. Looking for a natural cast iron finish that won’t rust for my restoration. When i started the engine, the paint peeled off like paper. It just cracked, split, and peeled off. Looks terrible. What’s the deal? Looked great before it got hot…….. $30 down the drain plus the work of taking them off again for something different.
