Anyone have any tips regards polishing paintwork? I got some fancy wax from a local company called infinity and although went on OK and polished off and looked good I noticed lots of tiny specs almost like tree sap that I had to rub really hard to remove. It can't be recent paint sap as it's never been left under a tree but I suppose could be 10 years of grime. Is this what clay is for? Also what about T cut? Or just plain old elbow grease with the wax?
