I have sucessfully sprayed clear over a variety of polished and tumbled aluminum parts, including a set of valve covers. However, within a couple of weeks I could see corrosion occuring on the valve covers. None of the other parts are doing this, and the corrosion actually started before the engine was ever fired up and appears to be speading steadily.
Has anyone else experienced this? And what would you suggest to do before recoating to prevent it from happening again?
