I failed algebra but first you will need to figure out your square ft of area that you are going to cover.. and how many oz. of product you will need per sq. ft.. the salesman for evershield ceramic surface treatmant says 4oz's will treat about 111 sq. ft of aluminum at .1 mil thickness...
a qt. will cover 893 sq. ft. of smooth clean aluminum...
Life's short...take your kid camping
