Black Witch neoprene Adhesive
For us, when it comes to wetsuits, this stuff is black gold.
Torn your suit a new entry? this'll fix it.
Fingernails ripped into the smoothskin? this'll fix it.
Seam falling apart? this'll fix it.
You should get it by now. Not dissimilar to the stuff used for liquid seams, this is a thick, black, tacky glue that amazingly has plenty of flex when dry so that your diy repair job doesn't go solid like plastic!
