Works a little, probs can't expect more
Mazda 3 2010 with severely oxidized clear coat.  Tried acrylic spray 3 summers ago.  It helped, but this summer peeled like a bad sunburn.  With oxidized clear coat still bubbling, and some touch up paint, used 4.5" grinder with nylon wheel 400 grit and very light touch.  Hand sand with 400 grit doesn't work.  Got lots of swirl marks.  See pic.  Applied 2 coats of this colored wax.  Uniformity a little better, bluer, but not much.  See other pic.
