grit on my paint

[asianguy06]

alright i got some grit like particles on my paint and i was wondering how to get them off without scratching my paint? another question is how to keep it off?

I would try to claybar the car to remove the contaminants.

Fallout and contaminants are hard to keep off a car but you can try a high quality wax or sealant. Collinite 845 would be a good option
