Front cap faded.

We have a 2007 Jayceo Designer. The unit is in great shape and looks like new. The unit has gel coat except for the front cap. I wax it twice a year with nuFinish , but I s still dull. I saw a Detailing Service do the neighbors unit and the cap looked like new. Of course they wouldn’t tell me the product name. Anybody have an idea what the product might be. He just used a small hand cloth and wiped the liquid on
Thanks Just m.
