i hav a 91 camaro used mothers three step stuff an the car looked perfect. then later during the week it rained when the car got dry i noticed white residue all over my car (my car is red) it doesnt come off with water it only comes off if i wipe (pretty hard) the area. its a vert an im guessing when i used the buffing machine small bits of the solution hit the top..water doesnt remove it and if i try to wipe it off it looks even worse like im spreading the residue over my black top. please help what can i use to clean the top or should i bring it to a professional detailer?
