Cleaning the outside of the 5'er do to oxidation

We are in the process of renewing our unit, stripping vinyls, removing oxidation.
Meguires #67 one step polish does a nice job, using a power buffer working one small area at a time and overlapping.
Then we clean with a 4" round brush on a drill with soapy water and Bar Keepers Friend.
Next will be wiping down with rubbing alcohol where new vinyls go then use the ' wet set' method of placing the vinyls.
