Sailor35, if you happen to find a used, non full-paint, that you really like, but has some oxidation on the gel coat, I found a product that puts a shine on it like you wouldn't
believe. Our used 2700 was this way, and after trying various polishes and waxes to no significant improvement, tried a "coating" that is supposed to last years.
found at marinestore.com , it is a 2 step process and takes some elbow grease. First you scrub off the oxidation and old wax with the supplied scrubber and compound, then you apply
the coating in multiple layers with a special applicator that builds up a really nice shine. Each coat only takes a couple minutes to dry since it is so thin. In taking it back to the PC factory this fall for a few minor things, the guys there were immediately asking what I had done to it !
To anyone else with oxidized gel coat, check it out !
