It'll buff out............................

Finishing touches. Beautiful coats of Yellow Peril paint. Skillfully applied decals. Just adding the last coat of 3M's 2 part Clearcoat. Then its done. Ready for the road. I was admiring my masterpiece when from out of nowhere on a still sunny day POOF, a random blast of evil breeze covers everything with grit and dust. For frks sake.

Anyone got any buffing advise using the 3M 2 part system or do I take it to the paint shop?

I've been through this with tiny flys and chiggers and even seed ticks getting in last clear coat layer before set up. Might just try a 400-ish grit to take off the grit layer then re-clear and buff out smooth with dry and wax and ride with the wind.

Paint the thing inside!!!! Also hang some plastic over it while you do it so no dust bunnies float in to the wet stuff.

Don't know if your going to buff out something landing in wet clearcoat.

You might be able to sand it out to the base coat and redo the clear.

Unless you are painting in a paint booth you may get crap on the clear coat. As long as it's the last coat and not trapped between coats it can be sanded out to just remove the debris and then polished out with Extra Cut compound.
Sand it down with 1500 grit as a final sanding.
I have painted many tanks and cars in my garage-shop. I made the big mistake once by putting on too many coats thinking more is better and too soon between coats and not letting it gas off enough between coats.
It made it real brittle and during the polishing process the clear coat developed tiny white spots where the trapped gas from the solvent heated up and turned white.
I now polish by hand to a mirror finish.
2 base coats and 2 clear coats is all you need with enough time between coats to gas off the prior coat.

+1 on letting the solvents out gas fully.

Thanks all. I'll sand with 1500+ grit and re-clearcoat. Painting outside is a necessity in an apartment building with hyper-sensitive neighbours. I've been through worse; when painting the hood of my TR6 car, I'd just finished the work and seagull shit on it. It made the foolish mistake of hanging around to mock me. Didn't last long.

Rather be out for a ride on a day like today. First warm day of the year.

Thanks again.

Might want to place in a big box to spray and definitely soon after to set up. Use many light clear coats rather than a couple of heavy ones or bad juju. Make it pretty thick for easy repair to most of the fates it faces.
