If you want it tight and waterproof, this is the go-to.

Best adhesive I know of for sealing and bonding at same time. Cures hard and resilient. It is my go-to if I want it waterproof and securely bonded. If you might have to remove it later without cutting, use 3M 4000. I always get this size, small size tube is way overpriced. It is gooey and gets on every thing so wear gloves and keep mineral spirits solvent handy to remove any smears.

sticky!

holy crap this stuff is sticky and it will get everywhere if your not careful but it will definitely put a water tight seal on anything you use it on. I used it to seal some speakers in motorcycle saddlebags I have no worries that they will leak

fast cure white is the best on the market.

i worked in the boating industry for 35 yrs. doing everything bow to stern top to bottom inside and out. the black is ok but takes quite a while to cure. if you really want an fast indestructable adhesive sealant use the 3m white fast cure. this stuff actually cures faster when exposed to moisture just as it says on the package. many many times i have used this on thru hull fittings, bonding wood, fiberglas, steel, stainless, aluminum and many other materials and it even cures underwater. it will cure in about 12 hrs. once cured it bonds to practically anything. i even use it to repair soles on my shoes if they come apart. then they are better than new. i have used this stuff wherever you need a serious rubber seal, bonding materia, even seals water pipes,fittings etc. i wish they had made it in black fast cure. not sure why unless there is a difference in the chemical makeup. it can be painted using enamel, polyurethane, laquer. not sure about latex, maybe acrylic. one thing is its almost impossible to cut or remove it.

Long dry time but bomber thereafter

This stuff takes forever to dry but once it does, it is great; hard and robust and able to take a lot of abuse. I use it to repair mountain bike shoe soles and moto dirt bike soles (that are gouged because of the pegs).

Will not cure, even with humidity or added water.

Most importantly this stuff will not cure even after 2 weeks! I don't know why it's is so finicky but apparently the consensus is it most likely will jot cure for you either.I purchased this because some users online said it was the best permanent bond for rubber/neoprene muck style boots and waders. However, like other purchasers, this stuff generally will NOT cure. I googled it and read that just like many urethane adhesives it needs moisture for curing. I am now trying to add water to it and and set a damp paper towel over it to aid moisture curing and my first attemp a few hours later the water seems to have liquified it more. I did have a small portion cure but the majority of it has not. I tried squeezing out a glob like you do with epoxies and then stirred water into it and applied it to some rubber. The left over mixed with water spot has not cured after a few hours. Don't get it on anything you don't want it on because it's quite greasy like and is difficult to remove. It gets into small crevices and threads but does seem to be out with lots of scrubbing but generally leaves a stain.I am wondering if windshield adhesive would just be a better product for bonding and sealing.
