There is no way to remove it other than wet sanding and buffing. If the dust is all the way through the clearcoat, then you have a real mess.

How much dust are we talking? The occasional nub or all over?

its not all the way through, I guess i would consider it minor but I wanted to try polishing it out. I have a variable speed buffer but dont know what combination of pad(fine, med, hvy cut, foam )and what grade of compound is to be used with each pad since you can get a wide range of each item mentioned. If I were to wet sand do I start with a 2000 grit or go higher . Ive even heard of people using comet cleaning powder to as an abrasive.

Start with wet/dry 2000 grit and use a flat rubber pad so that you don't end up making finger depressions as you sand the clearcoat. Use lots of water and add a small amount of dishwashing soap so that it slides better.

Wet sanding makes the surface flat so that the buffer can make it glossy.

Use caution and stay away from body lines as you can end up sanding right through.

2000 wet sand will work fine if it’s minor. You don’t necessarily need a pad if you sand in small circles and it’s a small area. You don’t need the soap if doing very small areas unless you want to. Just make sure either way to flush the sanded areas clean with clean water so all sanding residue (and soap) is gone. For buffing you can start with a rubbing compound and a wool pad. Then go to a finer polishing compound and a foam pad. Then switch to another foam pad and use a finishing compound. As stated, be careful around body lines and panel edges. The paint is thinner in those areas.
