The glue above is a neoprene based adhesive, not an adhesive for glueing neoprene!
The best stuff for glueing neoprene is Tivofix, but it only comes in gallon cans, next best is Bostick 2402 which is available in 250ml pots at about a tenner. Both are a two part (glue and hardener) which you make up in small batches as needed
