Using that Mothers polish will ruin the clear coat. Mothers specifically makes a clear coat wheel polish that is great...The previous owner of my GTA used mag polish on the Factory clear coated wheels and ruined them. Thus I spent $400.oo on Stripping, repolishing, painting, and clear coating. The wheel shop told me that is worst thing to do is use a mag/ alluminum polish as it will destroy the clear coat. Hope that saves you time and money.
Mothers clear coat wheel polish is what you need.
