I found an old pair of goggles in the closet, so I tried installing the patch.

What a PITA. First attempt was a bust. The tear is just deep enough that when I submerged and tried to unfold the patch and apply it I kept floating away. Second attempt with another patch went better. I smoothed it out with a wallpaper seam roller. Looks good...we'll see how it holds up.

Oh, and despite trying to be careful, I got glue on my hands. Looks like I'll have glue peeling off the next few days..lol
