Sounds like they steered you right. How do you get the inside patch in place?
The most durable drysuits on the market are stitched under glue. IN fact I would argue that stitching under glue is far stronger than just glue, since stitching alone is strong (but not waterproof). My point was stitching thru glue creates holes and difficulty where glueing over stitch is a common and effective waterproof seal with strength. OS Systems seams are incredibly durable for instance and completely air and watertight.
