Boy you got me. I can't figure a way you're going to cut through all that glass without making a big ball for the trash. Maybe you know a Zen sword master who could do it, but otherwise I'd forget about it.

All the glassing info I've read suggests a 2" overlap of glass on any joint or layer break for maximum strength.

I use 3" seam tape on the inside deck/hull joints of my kayaks and 4" runs of regular cut glass on the outside seams. I don't use finished edge seam tape on the outside because I found the finished edge of the tape always trapped air bubbles.

I suggest using the tape as is. Don't save a penny and sacrifice strength.

All the best,
