Paint won’t stick

I'm painting the trim ring around the headlights on the truck grill. There's a few tiny spots where the paint won't stick. After I spray it the paint pulls back from these spots. I usually wipe everything good with grease and wax remover before I paint but this time I forgot. How do I get these spots to fill? Is to late for grease and wax remover? Or do I just have to live with it?

sand it and hit with wax and grease remover, then respray.

You might be able to just spray a couple very light, dry coats then once that flashes off give it another wet coat.

I've been using very light coats. I've got 5 or 6 on now and it looks great except for these spots. I've now gone beyond my 30 minute time to respray and will have to wait 36 hours before going at it again.

When I would spray acrylic enamel. I always had a couple of fisheyes in the paint, no matter how much I cleaned. I eventually would use a little fisheye eliminator. You can't use fisheye eliminator in base coats or undercoats, only on topcoats. Otherwise, it's as suggested clean again and respray.

You should clean it with a good wax and grease remover before you sand so you don't sand any contaminant's into the metal and then again before you paint.

Contaminants are not always on the surface - could be in the air or the gun. Since you are beyond the respray window I would clean, lighty sand down, dust on the first couple coats and gradually go heavier.
