Rob -

Here is what I have done to remove gelcoat (and I have done a lot of it).
An air grinder, preferably a 90 degree, and a the "rough" 3M pads.  These
pads are about 1/4" thick and are a little spongy.  They remove gelcoat
controllably and also have a small amount of give.  Works much better than a
sanding disk.  They come in two different diameters, and have a "screw" type
of install - so can be changed quickly with different pads or disks.

As to the answers to your questions, I don't know.  Anywhere structural, I
removed 100% of the gelcoat.  Other places (certain cowl repairs) I got rid
of 95% of the gelcoat.

Good luck,

Matt
