Paint finish

I thought it was just me

 

Does it "go away" when wet? If so, just spot repair with more clear or shoot the whole panel.

 

Then something has "stained" it. Only fix is to strip and spot repair it. Whenever you polish, for lack of a better term, you open the pores until time/heat close's them again. Or the pray method, a LITTLE acetone and rub lightly. But only if it's in the clear, not the color.

 

No idea what stained it, maybe it was a mild "acid" rain. Have seen fingerprints, sweat, bird crap(LOL) show through from the oils after a cut. Wash with good water, even if you buy by the gallon, dry and wax. Years ago with acrylic lacquer's you would let it sit for a few days after each color sand/cut. Seen a lot of jobs ruined by someone/something touching it.

 

Regardless of how it happened, you'll have to shoot color and clear. Coarser sandpaper isn't going to fix it. That's why i asked if it went away while it was wet. If so you could just shoot clear again. Unless you know what you are doing it's better to just have a competent shop re-do it. Or try it yourself, blend in the color and shoot the whole panel with clear. You have to know how to adjust the spray pressure to get the right tint/fade on the color. It's urethane so #400 is plenty fine of paper. If you orange peel it just wait a few days, color sand it and rub it out.
