Lately I’ve been shooting a lot of stuff in matte clear (PPG Concept 2021 clear with their flattening agent in it).
I haven’t really done much with matte clears before, so forgive my ignorance.

I have a couple of dust nibs in the stuff I’ve already shot, and I’d like to knock them out by lightly wet sanding with 2000 grit. My question is, if I polish these areas back up with rubbing compound afterwards, will it come back glossy, or return to its original matte finish?

Thanks in advance gents.

you cannot sand or buff matte clear, hope you using the flattening agent just on your last coat of clear, that stuff cost me about $80 per quart when I did my GP

That was never an issue I ever dealt when I was mixing PPG. Most shops I dealt with really didn't bother with low gloss clear & those that did never said they have a issue like that. As for the wet sanding it could put a shine on it but have you thought of a test with a cleaning clay? It ment to clean up the top coat surface to get rid of the dust & dirt in it.

In general with flattened clears any sort of buffing , even a little mildest compound with your finger for a couple of swipes will change the gloss level. I'm sure same for clay bar. Usually it's sand & recoat only. Rule is NO.
Not that being said, I coat wood & stained fiberglass entrance doors at work with matte or satin clears. I have used a razor carefully to shave a nib & then either barely sanded with tip of finger & paper , buffed tiny spot with rag, compound, end of finger, Then lightly buff with white synthetic scuffing pad OR just the pad only. You'd really need to try a spot to see what you can do, but I have went back over spots with fine synthetic scuffing pad, sometimes a whole area to even out & called it a day.

A small trim part you can be pretty brave on, the center of a hood with no contrast to break it up,,eh?

Thanks for the replies guys. It looks like the general consensus is “no”. But with the caveat that it may be possible with a small amount of experimentation.

The tip about removing the nib and keeping the repaired area as small as possible and then scuffing it with a white ScotchBrite was really helpful. Thank you. I have all the necessary materials to make this happen, including the white scuff pad.

I have two areas where the nibs are really bothering me, one on top of the driver’s side belt moulding (right by the handle where you see it all the time), and on one of the steering wheel spokes I just refinished. Both in your face, and neither in a spot where there’s any real contrast to “break it up”.

I guess I’ll just have to get brave and try and find an inconspicuous spot to try it out on.
Thanks again for relaying your experiences with this.

Even though the steering wheel is in your face, the spokes are what I spoke of as a small trim part. If it's gloss level looks 5% different than another part of the car, doubt anyone would notice or care as long as it looks good & consistent..

I assumed you probably really knew the general answer was no with matte clears, but like me, don't care much for that answer.
With most painting spots I can't let go on entrance doors I do at work, as well as scratches I find in new glass, I'd say about 75% of em somehow are in your face, not in a corner. UGH....

Right?!? That always seems to be the case.
And you’re 100% right, although I truly didn’t know what the answer was, I still wasn’t necessarily prepared to accept it. I’ve always been of the belief that if there’s a will, there’s a way. But your suggestion has given me cause for hope.

I haven’t attempted the repairs yet, but I’m fairly confident I can pull it off relatively easily. I’m not sure when I’ll have a chance to attempt it, but I’ll be sure to post up my results here when I do.
Thanks again.
