clay bars are abrasive...don't do it too often maximum twice a year.Hi again. Just wanted to give a thumbs up to Turtle Wax ICE polish. I tried their liquid ICE claybar and the ICE polish. I think it did a very nice job...maybe not to regular wax standards, but the advantage is it goes on and off very easily and minimal time spent. My coupe has to live outside, so I reckon I will polish her every few months? -Bob.
