I must say, I have gone through a lot of sandpaper while working on fiberglass, but no more. Decided to try a couple new tools and must admit that these 3 tools in combination with each other are absolutely spectacular.
Dremel Saw-Max: Cuts through fiberglass like butter. has so much torque it twists in your hand when it starts (start it off the workpiece) and never gets bogged down in the cut.
Oscillating tool (Dewalt): with 60 grit sandpaper this thing shaves down edges like a champ.
Permagrit Wedge Block: Just like sandpaper wrapped around a 2x4 but doesn't wear out (hasn't yet at least) and doesn't scrape up your hand over time like the stuff wrapped around a 2x4.
Highly recommend these 3 tools for fiberglass work.

I've discovered that if I use conventional wrap-around sanding blocks much, I cannot use my fingerprint scanner to log into my MacBook until the ridges on my fingertip grow back.

I use them as well. Plus my Ryobi Angle Grinder with a cut off wheel, Ryobi Random Orbital (two) and Dremel.
I keep two grits on the random orbitals so I dont have to fish.
