Glad it helped Jan. I've found a dremel tool works in a multitude of places 
other tools won't.

One other thing in case you're not aware - when I was an apprentice 
machinist one of the first things we were taught is not only to have the 
right tool for the job but also to know the right speeds to use with 
various tools and materials. If you dont' have one yet, a speed control 
that allows less than full rpm would probably be most helpful in this 
application. It would keep the heat down and just allow the tool to produce 
dust. In this of application with fiberglass and/or hardened resin I would 
most likely use a coarse ball grinding burr and low to moderate speeds.
Hopes this helps. Please ignore if you're familiar with this stuff. 
Whatever works for you is the key. ;-)
