Thread: wet sanding?? painting ??

here is the way I do the paint and body work.

if it's been blasted and there is bare metal exposed, use a cheep primer because you will sand it all off anyway.

use a DA sander with 180grit paper go over entire car .keep a something to mark with in your pocket, like a lead pencil. while sanding stay away from edges, keep the sander flat dont get it up on its edge, mark hi/low spots as you find them . after you go over the car . take down all high spots, mix some filler to go on low spots. block sand with 80grit or 100grit. blow of sanding dust and reprime the entire car. get a couple spray cans of black very lightly spray the car ( I use a cheep black laquer primer in spray cans).

use the DA again with 220 grit and sand over entire car. again dont get on the edges. for areas the DA cant get to you must do by hand.

while sanding over the car, mark any spots you need to fill or take down, do them the same as before, with filler and 80 to 100 grit paper sanding is very important at this point the 220 will help get scratches out. so after the lows have been filled and blocked down with 80 or 100, switch to the 220 and hand block the same spots and make sure you feather the surounding areas. prime the entire car with a self etching primer.

next use 320 or 400 wet or dry paper, wet sand by hand . keep you'r hand flat dont apply to much pressure just let the paper do the work. keeping the paper wet and sand the entire car . dont try to take on the entire car at once you can do a section at a time this will give you breaks in between.

after the wet sanding wipe the car down with a damp rag and towel dry. while wiping the car down with the wet rag this is where you should be looking to make sure you didnt miss anything.

this is where you will make or break a good paint job.
next prime again . but this time you will just scuff the primer up a little . with 600 grit up to 800 grit. wipe the car down. and its ready for the paint to go on.


as for spraying the paint. everyone devlops there own mathod, what works for one may not work for you,
I keep a test panel in my paint boot to test my paint gun on before I spray the car.
