They are invisible. The test joints I made always broke in the plywood away
from the glass, and I was putting the pressure on the joint. This is with
3/8 superply and one layer of 6oz glass on each side, cut with the weave.

I have heard from one guy who said his would break in the glass, I would bet
that it all depends on the strength of the wood, he was using pine, CDX.
Make test joints, and break them.

Also, you can double the strength of the joint by using bias glass, or
cutting strips from cloth at a 45 degree angle to the weave. (all glass
fibers will then cross the joint)
