oh man that looks amazinggg!!..i love it! and i think you got a great price for that correction..also looks like i need to read into the 3m range of polishes..ive only used menzerna till now.
3M are very good mate, we use 3M and menz as sometimes one product works better than the other on certain paints.
Fast cut+ is tip top mate
and then refine with ultrafina or 85RD(final finish)
