Genny, How about one of the cyanoacrylate (Crazy Glue) adhesives? There are some water thin wicking (Loctite 420) that would soak into the weave. Just an idea. I wonder what the experts will say.

Probably the area I struggle with the most is the materials, like epoxies for board repairs, or adhesives, or sealants, cleaners, etc etc,...I did electrical engineering, not chemical. Is there any good resource place to get a handle on when you want an acrylic versus an epoxy, or silicone, or ... basic properties, what environment they are needed for, etc. A specific sourcing question I have right now - for challenging board repairs we use specially trained operators in a rework cell that use a 2-part epoxy to repair FR4. One product has a track cut, that usually causes weave exposure, that happens on every board on the line to allow for different configurations, and they want a way to protect it adequately with a 1-part quick curing material without sending it to the rework cell. We've tried those conformal coat pens, and they can be washed right off the board. Any suggestions?
