i primered my eg coupe and it was my first time painting a car but it turned out pretty good since primer is easy to spray. but it was kinda rough so i was told to lightly sand it with 1500 grit. so i did and it made it smoother like i was told but it got all scrathed and looks like crap now so now i am gonna respray and i was wondering what to do after i am done since that didnt work for me

 

what exactly are you trying to do? prep your car for paint? your post was a little confusing
