What is wrong with your hulls other than they aren't shiny?
Are they shiny when they are wet?

I had GREAT luck with Vertglass last year and that was easier than painting even. Mine were just oxidized and Vertglass solved my problem when I too was thinking I needed to re-gelcoat. Waxing just wasn't doing it for me.
Jake put me onto the Vertglass and if you do a search for it you can see results from a number of us with shiny hulls.
Good luck.
P.S. $ 75 bucks and The Catsailor on-line store carrys it or else Murrays does.
