The only advice I can offer is what I have learned from drilling holes into the gel-coat and fiberglass in a boat. You can minimize the splintering of the glass by making an initial cut with the hole saw in reverse. Sounds odd, but it works!! Once the surface is scarred in reverse, then set the drill or whatever you are using to normal forward rotation. Others have recommended covering the area to be cut with masking tape to minimize splintering as well. No warrantee or guarantees are included with this advice, but once you drill the first hole in the rig, the apprehension for the next one is greatly lessened!! Good luck,
Bingo
