So I finally got around to spending half a day (!!) polishing my hulls. I ended up going 600/1000/1500 on the wet sanding and then polished with a 3M rubbing compound & wax restoration product. I tried polishing from 1000 but wasn't happy with the results, but the 1500 worked great. Very pleased, if I can just keep 'em looking like they do now. Which leads to my next question...

What is a good product to wipe on to keep and protect my hulls so they stay nice and, more importantly, so I don't have to spend another day of my life polishing?
