If you've got the time, and something with a bit more kick than the 7424. Mine does the job, but I have been doing a lot of wetsanding and polishing combinations lately. I might even go back and have a shot at some of the real deep blemishes on my car.
Heck, i saw the weirdest one on my hood that's very deep. It looks like a + sign and a circle around it, like that old nordic cross type thing, but it's got the peace sign legs in it too. It has to be a millimeter wide/high...at the very most. It's so tiny, I don't know how it's in the paint. It must have been on a button or a tool that hit it, but it's such a sharp, small little indentation that seems deeper than what you would expect to come from something like that.
lol whatever, I've got some pegan ritual going on over the hood of my car or something...
