number of "coats" of paint

Color requires the correct amount of coats to achieve hiding. Be it 2 3 4 5 6. You can find this by doing a black and white spray out card. As far as clear goes, production shop 2 coats usually with a lite sand and polish. Resto work I do 2-3 coats clear, wet sand entire car with 600, and apply 2 more coats and done. Rarely will you have to polish a car after this procedure.
