Painting question Options

[Zaish]

So i am painting my front bumper using cans u can buy at ur auto store (did a 180 into a ditch and messed it up- quick fix)

So far i sanded it down, fiberglassed it, primed it, sealer primed it, painted 2 coats of paint on it.
Now it was coming along and getting that shine i wanted so i let it dry a couple of days to see if i should add more.... well i decided to go ahead and coat 2 more times as i didnt think it would hurt.
So i decided to wetsand it at 1500 just to scratch the surface a tad to get it to stick better after sanding it i started painting again but this time it started to do something i cant figure out:






Kinda hard to see as that was the best shot i could do but the paint i guess is drying too fast? I coated it with a very wet look. Anyone here know what could be causing this or if i did something wrong? This is my 2nd try to get it really shiney the first time it did this so i decided to resand it and try again... needed to fiberglass some area also....
