1993 240sx: how hard is it to buff car paint

[Anto]

see first if it's a two stage paint.
Many cheap repaints are only one stage, hence no clear.
You could buff it out, but you'd need to start with the least abrasive and work your way up the chart from there (in terms of compound abrasiveness).

To answer your questions:
No, you don't need to remove the clearcoat before doing this. When you compound with the correct product, it should remove oxidation without removing excess material. If your oxidation is beneath your clear, then the person doing it should see when to stop after doing some control spots.

Most likely if you got it done by someone they'd start with a medium cut pad with a light compound, and if necessary work their way up to using a heavy cut foam or wool pad with some medium abrasive compound..

look it up before doing anything, if you value your paint and try to keep it in good condition, then you should pay someone to do it.


OTHERWISE, if you dont care just start rubbing away with 2000 grit sandpaper, finish it off with rubbing compound and finishing compound, then wax
