||The wheels had been laying in the workshop for almost a year, and had not been cleaned in all that time. I was amazed at how well they cleaned up. I used metal polish and, after hours of carefull cleaning, I think they have cleaned up nicely.
After polishing, I masked all areas off, and gave the chrome several thick coats of lacquer. This is perfectly see-through, but will make the chances of these ever rusting again very slim. Plus it helps when I come to clean them after use and surface dirt just wipes away easily.
