I just painted one of my work trucks. I'm a mason (rebuild a lot of chimneys), and I'll use the truck for this and other mason work. I toss bricks and debris from the roof tops and usually a few bricks bounce out and land on the roof and hood. Short story of this is no matter what I did to try to minimize the dust it's there. I don't want to go through the whole process like I did with the jeeps (not worth that much work for the finish and I actually got minimum orange peal). What would be the highest grit paper I could use to just knock the dust out. Don't want to start out as I would for orange peel if not needed. Here's some pics. Thanks.

If you are going to be bouncing bricks off it, I wouldn't worry abut that little bit of dust.

I thought of that but I did a stupid mistake on the pass door. Had the hose run from back of truck and tried to flick the hose when shooting front fender and hose rolled and got the door. Went right back and re-shot the area so I can wet sand that spot. Was just hoping that a quick sand with 1000 grit than 1500 would get the sharp part of the dust (when you run your hand on it) off.

Try some 1000 using a hard block (I use a small piece of oak) and wet sand the area. You will need to be careful to rinse often so as not to scratch up the area with a speck of dirt caught under your paper.
Go over that with 1500 grit wet on a soft block making sure to remove all the 1000 grit scratches.
A rotary buffer with a twisted wool pad and Megs 105 should buff it up pretty decent.

Thank you. Was actually proud of the way it came out (no runs or dry spots), orange peel similar to today's car finishes (amount of orange peel). If it would have been the jeep project I shot last winter it would have been a easier buff. For some reason got more dust in the paint and seems to be more like it's just under the last coat or two.

Static electricity can draw the dust into your paint job. Might try a grounding wire next time to see if it helps.
Wetting the floor prior to painting also will keep the dust down.
Most of the dirt comes from off the painter. Wearing a paint suit, gloves and painter's sock helps immensely.

I put down around the cab new canvas tarps, then did the final wipe down with a 3m wash. Just dawned on me I forgot to then do a tack cloth wipe down (brain fart), that also didn't help. I'll go invest in a painters suit also, as well as try wetting the floor.
