So you say tripple would never correct, but yellow dave says "I've watched people burn through clear coat with a DA with a light polishing pad and polish"
Well yeah..........
Tripple is not an abrasive corrective polish. It cleans paintwork, fills swirls and lays down a layer of protection. I used to about 2 hours ago in fact.
If you want to remove swirls completely then you need a machine polish er like a DA, Flex or Rotary and an abrasive polish/pad combination, like Megs 105/205 Gtechniq P1 etc. What you're essentially doing with an abrasive polish is removing clearcoat. The amount you remove depends on the polish or compound and pad you decide to use, based entirely on your own judgement. If there's only 2 microns of clear coat left and you machine polish that particular spot until 2 microns are removed then youll burn through to the paint itself. Thats what Dave was getting that. You need to start at the bottom in terms of pad and polish combo and work up wards from there until you get to combination of pad and polish which removes the swirls without removing more clearcoat than necessary.
If polishes and pads worked on a scale of 1-5 (5 being the most abrasive), and it took a combination of 3-3 to remove the swirls in your paintwork, yet you jumped the gun and went straight to 5-5 then youd be removing more than necessary, producing worse results and risk going through the clearcoat if certain areas are low. Its about getting the right balance. it doesnt take long.
Theres a guide somewhere by Dave KG (Maybe stickied) that explains all that.
