Electric sander/polisher or an air sander for paint finishing?

Have finished painting car and rubbed down with some 800 grit by hand. I dont want to do anymore wet sanding by hand. I see you can get 1200, 1500 amd 2000 grit 6inch sanding discs but don't know what sander to get. The electric ones seem very expensive £50-£100 for somethin decent. Looks as though the rpm can be easily set with an electric sander/polisher. None of them seem to have da function though except for ones that work over 4000rpm that would be no good for polishing also.
Anyway, since i have a compressor i thought it would be cheaper to get a da air sander, these are much cheaper £15- £40 for what looks like good quality ones. But i dont know whether they are suitable for finishing paint with 1500 grit and also for polishing with foam pad and g3 as there max speeds are about 10,000rpm which obviously would burn the paint. presumably i can just set the regulator on my compressor to lower pressure and only pull the sander trigger a small way in to get lower speeds.. but doesn't that mean i am guessing what rpm the sander is working at all the time?? will that work?
Very confused !! appreciate any help ta.

Dont be lazy, do it by hand. IMO you will get a better finish if you take your time and do it by hand. very low risk of burning the paint. and exercise at the same time

lol its not cheaper if it takes me xtra days that i cud hav spent at work earnin OT. I think i'll do it by hand up to 1500 or 2000 grit and then i'll use an electric polisher with a foam pad and sum G3 after that. ta for replies

It doesn't take that much longer if you rub down wet.

have you really flatted the car after painting with 800 grit, thats far far to course.

How many coats of topcoat or clear did you put on?

If you have used 800 your likely to rub through if you havn't already.

Good luck with the 1500 but I fear you will be getting the spraygun out again.

I used 800 on mine, it came out fine

I would say 800 is to corse for colour sanding, your more than likely get scratches in the paint from the corse paper, I dont go any lower than 1000 grit.
