Depends on where boat lives to me? If the boat is at your house then what I would So is tape the spots perfectly. Apply gel with hardener and cover it with wax paper. Let it set up for a day and the repeat..over and over and over till its tall to surrounding tape. Then Id hit it with 600-800, then wet 1200, then tape off and buff the crap out of it. Wont look like Garry wright did it but til be ok. If you want it done right you call Garry wright at wright way boat repair in lakeview(3 miles from bcb plant)C.O.D. Jr. III
