Can you explain how to color or wet sand (same thing?), what grit, process, etc. My Blazer has a descent paint job, but there is some orange peel and I'd like to get rid of it. A body shop said they would do it for $500....no thanks. I had a guy explain it me real quick, not much detail, and it doesnt seem like it would be that difficult to get it to shine and get rid of the orange peel, just some time and patience. Thanks in advance!
