Went to clear coat my headlights after I sanded and removed all the yellow oxidation.
Final sanding before applying clear coat was with 3000 grit.
The temperature inside the garage was ~59F.
I first applied light coats then little heavier coats after. Both came out dull/milky but some of it went away.
Figured I'd give it 24 hrs to cure and maybe clear up but today it looked dull with minimal milkiness.
I don't think their was much humidity in the air as the temperature wasn't that high.
Any tips for avoiding this?
