What's the best tools to safely and effectively removing the old gel?

There's a thing called an "air file" auto body shops use.

It's a linear oscillating compressed air driven sander about 18" long
and 2.25" inches wide. I've been told they work pretty well with 80
grit and they have less chance of digging into the fiberglass than a
rotary grinder. Since it's air driven, I suppose you could safely use
wet sanding and avoid the dust.
