Bringing her back to life

[Louisianav20]

Looking for some help bringing my fiberglass back to life. I have a 79 V20. Brand new mercury, brand new gauges amd electronics, and brand new top. Now its time to get the ole girl shinny again. Whats the best advice that yall have for this. I know some wet sand, at what point is that the best option? I know some others just use oxidation remover or a cutter and rewax it. Thanks for the help.
