The Stovebolt Site Forums The Shop Area Paint and Body Shop Trash in single stage paint

This morning I painted the fenders and running boards of my 37 1/2 ton (off the truck) with single stage acrylic urethane, black. The paint was laying on nicely, but unfortunately, between coats the weather changed drastically, and to make a long story short, I ended up with several bugs, a fair amount of nibs, and a small area on one of the fenders that looks like "solvent pop" (not sure what happened there, but probably some contaminant on the surface, or some moisture in the line (it got quite humid quite quickly). At any rate, I now have fenders (the running boards are fine) that have a pretty nice paint job on 90% of the surface, but marred by the trash, etc., here and there. My first impulse is to wet sand everything with 600-800 grit and shoot another coat (I have enough paint for probably one more good coat). Is there an alternative to that plan?

Can I try sanding and buffing out the trouble spots, or will that just end up making a bigger mess? I have a set of nib and run files that I can use. If I can sand and buff, how long should I let the paint dry--tech sheet says 16 hours. There are three good coats of black on the fenders.

I've painted a fair amount in my semi-sheltered set-up and have always had a bug or two--but never this much trash here and there.

Any advice will be greatly appreciated.

Thanks,

Jim

Try wet block sanding with 1000 grit and buffing to see if you can bring the gloss back without a recoat. Worst case scenario, you've just done a good prep job for another coat of paint. You might get away without having to spray another layer.

I painted my entire truck with single stage last year. Let it sit for a day, then take the run files to it then go no coarser than 1000 grit wet and you will be able to tell if you can get by without re-coating at that point. Then to 1500 and on to 2000. Then break out the compounds. I had a lot of trash one day after shooting the fenders but was pretty surprised after the run files and 1000 grit.

Thanks, guys. I will follow your advice--as Jerry says, the worst that can happen is that I'm preparing for another coat if it doesn't come around.

With three coats on her you might hopefully get by. Good luck to you and let us know the outcome.
