Sure,One Clean the
hull throughly,all stains should be removed use a hull cleaner such as mary Kay closely follow diretions.Next scrub with a mild abrasive cleaner Soaft Scrub ect,Now test a spot with 1200 grit wet sand paper test another spot with a medium rubbing compound compare,If the 1200 grit wet sanpaper looks better go with wet
sanding the boat be careful not to rub to hard as to go thru the Gel.When done use a fine rubbing compound with a electrict buffer.When complete Fleet Wax buffed Don't let dry Buff in while still wet doesn't take a lot.Boat must be on the hard not a job to do in the
water.Keep my 30 yr old boat looking good once the initial process was done a yearly waxing was all that was necessary.Good Luck
