gel coat

I'd like to hear from the professionals about the best way to remove old gel coat without damaging the underlying glass. There are a lot of suggestions out there (air file, very coarse random orbital sander, etc. etc.) and when I did it (once and for the last time, I swear) I used a fairly coarse hand held belt sander.
What do you guys use for this job? On flat surfaces? On compound curves?

The picture about midway down the page on Richard's blog pretty much mirrors the way we do. Same tools. Same papers. Same hand-sanding blocks. I've actually been creation a Bill Of Materials on Amazon that has most of our stuff. Maybe I'll get around to cleaning it up over the weekend. It's at least good as a starting point...
