Prep for Paint, need sandpaper advice

use 800 then 1000 for the primer then use 2000 for the base color then 1500 then 2000 for the clear. Thats what I use for some it may be different.

180-220 prep for the 2K primer then block with 400-600 for the topcoat prep. ugh, I hate sanding! Take your time and she'll be purdy. Good luck

where do you plan on painting the car? and are u shooting it yourself?

Its been some time since I did mine but I the lowest grit I used was like 380 to start...

the nastier the grit the more the sanding marks you have to take out...and believe me they'll show. I would stop by a local shop and ask their input. Alot depends on the shape of your paint and the clearcoat.

Use hi-build primer to hide the sanding marks from repair areas... hi-build covers and fills alot of sins and sands out easy....use guide coats to get and keep things flat when sanding...

touch bases with someone before you start is my best advice, especially if your learning...you can make a mess real quick....

800-2k before priming...

180-220 before priming, 2k is usually referred to high build primer, sorry about that. 800-2000 wouldn't provide nearly enough tooth for the primer. So in a nutshell, scuff your car with 180-220 enough to reach the base coat or prime but avoid going down to bare metal as then you would need to epoxy or etch prime it because most 2k(high build primers) aren't recommended for bare metal. Spray your primer and block with 400-600, the later for metallics as metallics will show sand marks easier, and repeat if necessary. As said above use a guide coat and sand it to show any low-high areas. 1500-2000 your final coat, hit it with the high speed buffer(wool pad) using a quality medium cut compound such as 3M's Finesse-it II, high speed it again with a glaze and foam pad, wax it and your done.
