restoring gel coat methods

[bluedog]

I still hear two diffrent schools of thought on trying to get back a shine on a heavy oxyidised hull. I'm talking no reflection and a white palm after running your hand over it. One is the sandpaper veryfine grit many grades or rubbing compound then finness. Has anybody brought back a shine using this or anyother method? Then there is this other one I'll try to give you the link.
