Also a former boater who has tried just about every product made to try and keep a black gel coated boat sitting in sun docked at a marina 6 months a year. Two products I settled on were Nu Finish as my wax and 303 as my protectant for vinyl seats and upholstery. Also used 303 on the black gel every few weeks. When I sold my 8 year old boat at top dollar the black gel looked like new. After thinking of switching to Rejex or something new for my 35ft. class A, I decided why switch from the success I've enjoyed with Nu Finish on my boat and first class A. Only thing I do different is I use cheap dollar store furniture polish on the front cap and chrome wheels as a touch up spray for a fast shine before trips. Eagle1 does make a real nice spray on wax too if I see it on sale.
