Inside and Out - Best Sandpaper to Use before Painting...

As i'm sure you've seen I have most of my interior painted, I have painted something and it is peeling right now, I want to resand it and repaint it but I am unsure of what the best grit sandpaper is for the job, I want to sand all the rest of the paint off and start new...any suggestions?
Thanks Civic Tuners!

3M's wet/dry sandpaper (the grey kind). use maybe 1000 grit if you're trying to remove paint

i dont think 1000 will leave a rough enough surface for good adhesion, its great to polish with, i'd go 400, and then after you paint polish it up 1000

use the sandpaper after i paint?

yeah, 1000 grit is almost like regular paper, so it will just polish it up good, as long as you dont sand too hard or too long.

ah i see
i am going to paint and then cover it with gloss clear coat, do i sand after the clear coat or after painting and before clear coat?

also where can i get this? i looked at lowes and they didnt have any...

most Kragen/autozone type places have it, and i think its best to sand everything but the final coat, as that will show the fine lines, but its paint, so you can pretty much just fix anything you mess up, as long as you dont REALLY screw up. just sand the paint, then clearcoat it, sand that, and see what it looks like. if it looks better unsanded, apply another coat of clear.

okay, thanks for the info man...

i think its best to sand everything but the final coat, as that will show the fine lines,

actually, you do sand the final coat. thats how you achieve a "mirror finish" with painting. start with 1500, then 2000. and then after that it will be smooth but still with some fine lines. you use rubbing compound to polish out the fine lines left over and then apply some standard car wax to buff everything up once its cleaned off.

i suppose though that it won't matter if you're just doing some interior painting, unless you're really anal about orange peel

ahhh, good call. i didnt even think of polishing compound...

i think all of this is gonna confuse him. sand your car with 400 grit paper only before the 1st coat of color. after all of your color coats are on and all of your clear coats are on and it is dry, then sand it with 1500 grit paper and buff it with a buffing compund. if you dont have access to an elctric buffer then dont sand with the 1500 after painting. just deal with it not being super slick. and by the way paint will stick to an area sanded with 2000 grit paper. so you can sand the car before painting with as fine as you want, but its all in the patience you have, but the finer you use before paint the easier it will be to make look good after paint

stubbs lays it down :D

its the interior, so an electric buffer wouldnt be very easy.;)

oh, when i read it i thought he was saying he has painted a lot of his interior and was moving to the outside[sm=oopssign.gif]. well then just sand with 400 and go at it again, but dont sand your color between coats or before clear
