Thanks for all the input guys.
I ended up getting GelCoat Labs - Color Restorer/compound and Micro-Polish/sealant.
Using a rotary polisher I removed the oxidation and previous waxes down to clean gelcoat. Bringing back some of the shine. Then the micro-polish really shined it up and sealed it and made it smooth like glass.
Tomorrow I will add a coat of Turtle Wax Ice synthetic paste wax, which will make it super slippery. (It can be put on a hot sunny surface)
I plan to hand clean the bugs on the front cap with mild cleaners in small areas at a time, then re-wax it with a spray wax TW Ice makes for touchup detailing.
After a few months on the road I'll know how well this system works and try to remember to post results here. If I forget, someone just post a question here for me and I'll receive an e-mail notification, reminding me.
