Marine Goop aka amazing goop marine

[divezonescuba]

Curious as to whether anyone has used marine goop for replaceable neck rings and wrist seal systems.

I used it successfully (for now) where aquaseal and neoprene cement had failed.

it is clear and drys just barely flexible. Much less flexible that aquaseal.

Yes, it's pretty good stuff. Sticks to some things, but not all, better than Aquaseal. No idea how well it bonds to latex seals. Not sure which one ages better.

It's my understanding that Aquaseal is a urethane, and Goop products (along with Shoe Goo) are a "synthetic rubber" in a separate class of chemicals. Another synthetic rubber adhesive sealant worth comparing is Lexel, available from most hardware stores. It's extremely stretchy and sticky. Dries slow if not exposed to air.

With any of these things, surface prep (aka, the surface energy of the material you're trying to bond to) makes a huge difference.

If anyone on here is or knows a material scientist who truly understands this stuff I would very much like to speak with them. My knowledge of these things comes from trial and error rather than a proper sense of the chemistry at work.

I've used marine goop extensively. As it ages it relatively quickly becomes rock hard. Shoe Goo stays somewhat flexable. Were it me I'd look into flex seal.
