I'm relatively new at "machining" paint. I have practiced on the fiberglass door shell of a Saturn. Im comfortable enough to try it out on my truck. I have a black 2005 GMC Truck. The truck has fine-medium swirl marks from washing/drying (before I discoverd that polyester caused these). Ive learned how to use my machine (Porter Cable 7242), however unsure how select which compound/polish and pad. I was told that GM uses a hard clear coat. I need help selecting a good starting point for this type of clear coat. Any help with foam pad (brand, color) and polish/compound selection would be of great help.
