Excellent work! That monitor should be good for many years to come. Capacitor failure on Viewsonics is a common issue and there are repair kits available on Ebay to address the issue. The monitors are so well made, that bad caps are just about the only failure after many years of service. Quite remarkable for a piece of computer gear. While the monitor is apart, I suggest carefully checking all the caps for any sign of swelling. The Ebay kits feature all the caps on the board and they are better quality. I wouldn't replace all the caps, just the bad ones, as you can damage the board when you solder.
It hazes into a dull silver color. You can buff it out but that removes the clear coat. The big issue is using a chlorinated cleaner on a painted surface. Most alloy wheels are painted with pigments or a clear coat over polished metal. This paint should not be cleaned with chlorine.
I would stay away from any cleaner that uses bleach. That will damage the finish on wheels and cause rust.
Household bleach (Sodium Hypochlorite, NaOCl) is very alkaline and can etch or destroy the clearcoat on most alloy wheels. It breaks down into salt which can begin to oxidize the unprotected metal. It also dries out paint and can de-color any pigments. While a fully diluted solution can be used on protected (waxed) paint, I still prefer using car shampoo instead. It should be ph neutral and free of harsh chemicals.

Use a sharpie to mark the center of the bit before you grind it. Otherwise you may end up with an off-center awl.
