Hi group,
I just polished up my new to me 94 Hobie 20 hulls to look like new. On one hull I first used 600,then 3M rubbing compound with a buffer(not orbital) and then I buffed with 3M marine fiberglass cleaner/wax.I used lambs wool pads. On the other hull I just went right to the cleaner/wax. I can not tell them apart.
Happy holidays
Ken
