My burgandy gel coat boot stripe was dull oxidized, looked horrible. I had nothing to lose, thought I would have to paint
or apply vinyl decal. So I used heavy compound
wool and lots of elbow
grease. Then instead of wax which I had been using, I used Poliglow (goes on easy, drys fast 1-2 minutes, 5-6 coats took half hour to apply to 30' boat
2 sides. Still looks like new after 2 years. Trick is hard work
on prep, surface will look dull and scary but as long as it is even, whatever you put on top should look good. Try small test area. Good luck!
