I've never tried it, but don't see why it wouldn't work. Any way just throwing it out there for any who may run across a chance to give it a shot.

Use fiberglass insulation to mix with the resin (or possibly putty) for small fills for extra strength.

That's it....

Since I am often tinkering with this sort of thing, if I use it, I'll post whether or not it is worth anything.
