Im puttin CCOT's quarter panels and rocker panels. Got one side welded on and I ground the welds down...whats the best way to get rid of the scratches left by the grinder?? I would like to get it smoooooth before i prime her :)

Body filler. The new generation of Bondo-type fillers work well and are easy to work with.

Sanding disk. get a fine sanding disk for your grinder and it'll make it smoother than a baby's bottom

Matt:skull:

flap wheel for your grinder than reguler old sandpapper:jeep3:

small stuff, I have a pistol grip grinder w/ 2" scotch brite disks (roloc type)(various grits).

for big stuff (only if you have lots of air, minimum 80gal) a Dual Action (DA) sander.

sandpaper disks or flappers are too fast/coarse.

Body fillers (less than 1/8" max) and green glaze skim coat.

Flap discs work excellent.....:skull:

i use some little snady, looks like lizard skin, kinda thang!:flipoff2: its like a disc of overlapped sandpaper. i get em at harbor frieght, but a sander pad on the ol grinda is bad ass 2!!:rasta:

not even a newbe,

thats what a flap wheel is:jeep3::flipoff2:

use some bondo if u can't file the metal down to get rid of the scratches, for the best results do not use a electric or air sander, use a flat board thats about 2 inches wide and get sandin, thats for show quality finish though. and go down to about 400 grit before painting, good luck
