i painted a passenger side fender for my car i the color came out fine but i just finished putting dupliclor clear on it and there are some round gray spots oops how can i remove them??i was thinking wetsand but what grit??and what can i do the fender to make it like a mirror its glossy just not enough for me ya know any help is greatly apprecitaed

 

the round grey spots sound like the humidity was a bit high for the clear. sand the clear off and see if you need to recoat the color then reshoot your clear and do a color sanding in between coats with about a 1200 grit then final sand with about 2000 and do a clay polish for the mirror shine
