When we picked up our new to us 98 Bounder (With gel coat.), it was in need of attention.
I spent a few days using Zaino AIO (All In One) product. I did my my hand, and it did a great job of cleaning up the gelcoat. (The 1st owner lived down the street from us, and he came by a few days after we were done, and said the last time he saw looking that good, was when it was new. (And we were lucky, as his wife had insisted on new decals about three years earlier, so they were in great shape.)
With the reality that quality of the gel coat finish is far superior on the CC then the Bounder (Not a knock, but IMO a fact!) - you should have a good chance of getting this looking great again, if it's not too far gone... Have used it on a friends boat too, and we used a orbital polisher for that job.
One of the great things about the Zaino (I've been a fan of all of their products for years, not inexpensive, but all do a great job. I use their ZCS Clear on areas I want either protected from UV, and or on the windshield as it is like Rain X on Steroids!) AIO product, is that it also leaves a protective layer (not wax) on the gel coat too. So one application of 'Wax On/Wax Off'.
Not as good, but less expensive and at most auto parts stores, is the TR3 product. (Does a good job of cleaning, but the protective layer does not last near as long as the Zaino.)
Best to luck to you,
Smitty
