Sanding out orange peel in clear what grit to use first?

Be prepared for a novice it could take 40 hours or more to complete. Take your time do a panel at a time if you have too and cover the rest of the car.

Change direction when you change grits to remove scratches from the previous grit. Do NOT sand what you cant buff or you will end up hand rubbing it out which is not high on my list.. Actually, it is not on my list at all!

When you get to the buffing stage wash between compound stages and clean or tape off jams and corners. Compound once it is hard is like concrete. Get it off the car. I use 3m 3 step compounds. Others have their preferences and I am sure will chime in. Good pads and compounds will run you +/-150.
