I had my Edelbrock 573 tri power manifold powder coated with a cast aluminum looking powder. It looks really good but doesn’t resist staining from gas leaks at all. Because of tuning issues and other things I experienced a lot of fuel staining which leaves the yellow stains that are impossible to remove. I probably tried everything known to man and everything posted in different places online. None of it touched the stains. So right now the manifold sits on my work bench and I’m taking it apart for re- finishing. I’m going to weld some aluminum pieces into the exhaust crossover ports under the middle carb, previously I had them blocked off with the gasket and thin stainless steel. After that I want to have it re done. Here’s the question. What finish will be best to avoid future staining from possible leaks? Don’t forget that I’m running Strombergs A different color of powder coating? Or maybe polishing the intake? Or chrome? Or just blast it and leave it on the work bench? I love the Tri power and the Y Block looks and runs great with the Strombergs but this is frustrating.
