Aquaseal substitute?

[Aqua-Andy]

I have just used the last of my Aquaseal that came with my Halcyon p-valves and was wondering if there was a tried and true alternative? From what I have found by searching the internet is that Aquaseal is just expensive shoe Goo and Cotol 240 is really Toluene. Has anyone tries these substitutes and if so how did they work. I just can't see spending over $10 for the Aquaseal/cotol 240 when there might be an alternative for much cheaper. I already have Shoe Goo that I use to repair my RC car bodies and they both smell and look the same, they seem to have the same curing time also.

I've used Marine Goop to laminate harness webbing onto a maglite sheath to make a sturdier sheath for my knife. I've also used E6000 to reinforce the edges of a pocket that I originally glued to my drysuit with Aquaseal. Both products have withstood many dives without deterioration.

I've Shoe-goo'd boots and gloves and have stayed water sealed. The seams on the boots lasted longer than the fingertips on the gloves.

Aquaseal, Shoegoo, some wader repair compounds, etc., are all urethane cement. The smell is unmistakable. It is sold under lots of names, including 'urethane cement'. Just check the small print when it's sold under names indicating a narrow application, like shoe repair. Plain toluene is the quick dry chemical.

It is wonderful stuff, able to permanently bond flexible vinyl. It retains a degree of flexibility, and is often stronger than the materials it's bonding. It's excellent for applying patches or pockets to neoprene. Don't get it on your fingers.

Depending on your load bearing, Neoprene Cement can also be an alternative.

It has a bit of flex after curing, where as Aqua Seal becomes rigid.
It also only takes 15minutes to prep and an hour to fully cure for small applications.
The benefit I see is am opened squeeze tube of Trident Neoprene Cement lasts much longer than an opened tube of Aqua Seal.
Downside is you need to have porous fabric on both ends for a good connection. You can also cut through the connection since it isn't a rigid solid glue after full cure. (Benefit or Downside). Say if you wanted to remove a wetsuit pocket after the wetsuit's career.
After a full cure, the connection is also slightly tacky until you rinse it in water.

I've used it for knife sheaths and attaching a Tri-glide to my old stock BC so I could attach a crotch strap (used scrap neoprene to loop the triglide onto the BC). Both have held up perfectly.
Wetsuits are in fact held by neoprene cement. The stitching is just to keep the material from stretching and putting strain on the glued seams.
I'm confident it would also hold the weight of a loaded bellows pocket as well.
