I just painted my sons truck (base coat clear coat)It looked awsome.After the 4th coat of clear I was very satisfied with the job .I live in the country (dirt roads) and an idiot came down the road and saw the truck drying still ,and did a couple doughnuts .I got lots of dirt in the clearcoat...My ???? is (do I use a DA with 1200 wetsand or do it by hand or what) I am afraid of getting scratches from the sand...Any help would be appriciated..Grits? equipment?

awww man that sux sorry to hear such JO exist!

Im no expert but Id say ur better off wet sanding by hand and rinsing OFTEN, I think the DA may make things worse.

I gotta ask cuz Im kinda surprised to hear that u had good results spraying the truck outdoors w/out making a plastic booth. Was this ur first job?

Thanks for the advise against the D.A.I really apriciate it.No I have painted 5 0r 6 before but I still am getting set up and my garage is in need of flourecents yet,so it was a nice day out and decided to go for it. I'll be getting the lighting problem solved this week. I should have known better.
This forum Is awsome for a guy like me who is trying to get it right....Thanks to all..

I think you would be better off wetsanding because yes doing it by hand could scratch the paint. Hope it helps. sorry to hear bout the bulls*it.
