Can anyone tell me the proper way to clean/refurbish my aluminium valve covers? They are the originals from the 69 Q code car and have never been cleaned.
This is best (not to blast them)... I want them to look original but not perfect.As Brian stated; It depends on what you want them to look like. If you want an original type finish then do not blast them. Soak them in a solvent, such as carb cleaner and lots of elbow grease. They were not "polished" from the factory.
