I've tried a lot of different waxes, but, always wind up coming back to NuFinish. I got hooked on it when I had a big cabin cruiser that was all fiberglass...it is good stuff. Goes on easy, lasts and has a good shine. My next choice would be any of the Meguiars products. I'm currently experimenting with their NXT Generation Tech 2 wax. Goes on like the NuFinish, but, showed swirl marks (may have been my application technique), but, seems to be holding up well.
My 2 cents, your mileage may vary...
