i used the new Meguiar's Ceramic Finishes. This works great if you read the instructions. I let the stuff dry and it took a few washes to get the graphics clean again. But, now, I rinse and the RV shines.
I go over it lightly with the Meguiar's Spray Detailer or Meguiar's Wax spray.
I get comments, mine is the 2nd best shine in the RV park....
Any oxidation, i put a dab of polishing compound and buff out.
