believe it or no i used meguiars #4 on my gp and it took out all the swirls and most of the acid rain…took 5 hours after i applied wax though…lol.My dads buddy told me the most important thing was to do a cross hatching with the orbital to avoid swirls(Side to side then up and down).what other tips would u have??
