hello all, today i wet sanded my passenger side headlight today cause a long time a go i FUBARED when i used goofoff to try to remove a stain. stain came off but i guess the goofoff somewhat melted the plastic. so the cover became all grainy looking and foggy looking. finally after months of working, i have a weekend all of from work. i was going to just another headlight but decided to try to fix it. so i went to the body shop story and bought some 1000, 1200,1500 and some 2000 wetdry sand paper. went through each of them. while the headlight was wet, it looked 100 times better but when it dried, looked all white and could barely see through it. so am i missing a step here. should i buff it out and if so, with what?
