I own a 19 year old high end 5th wheel with gel coat finish. Its been in the Florida sun the whole time. Tryed many products to renew the shine. The Meguiars4965 was awsome. It is a lot of work but the finish was restored to a higg luster.
Works well restoring the shine to my fifth wheel. It does a great job on fiberglass gel coat. This is the best system I've found to restore this finish.
