Wet sand sealer
 

OK I used HB primer and sanded to 320 then shot 2 coats of sealer. Now I need to wet sand with 600 before I shoot Base. ? Do I block the 600 or use my little 3m sponge that I use to wet sand the clear? I have always shot the sealer wet on wet but wanted to go the extra step on my own car.

When I wet sand my sealer I just use a peice of used 400 grit and hand sand it very lightly. Seams to work fine for me. By the time your in sealer you shouldn't need to be doing any more block sanding. That should have already been done with your 2-k primer.

Sanding sealer is optional. If I have to I sand it, I sand with 600 and shoot base next.

i wet sand with 600 no block just hand sanding Unfortunately When it comes to body work and paint 10 people do it 20 different ways

if you have any dirt, trash or orange peel, it'll need sanding

Seems it always need sanding:D:D:D
