HI all, any recommendation for the best cement/epoxy whatever to reglue the back of my deck pad (raised end bit of a JL World wide) that came off a couple of years ago and which i glued back with marine expoxy but that has lifted again. Obviously I did not do a great job then or may be the marine epoxy was not the thing to use. Thanks for your advice.

Contact cement stays slightly tacky and you join pad to board after 10 minutes wait time till it gets tacky/sticky.

MS Polymer glue. See my posts:

MS Polymer are extra strong, stay supple, and are solvent-less (so they do not damage the board). Contact cement use solvents, this is why you have to put on them on both surfaces to dissolve them, and let the solvent evaporate. MS Polymer glues are both stronger and more practical (you can reposition them for 5 minutes, and since you only put them on the pad, no need to delimit the proper area to put glue on the board).

Clean with Acetone
Use 3M General Trim Adhesive
Its a spray on adhesive.

NEVER clean a board with acetone!

- it is hyper dangerous for your liver, and it goes through the skin.
- it risks destroying your board: the resin itself is safe, but it risks dissolving various chemical addons in it, creating micro-cracks and pinholes... I have seen the paint on a blank messed by acetone UNDER the glass, without visible damage: the acetone had created micro cracks and migrated to attack the paint underneath.
- acetone is so volatile that it evaporates before unleashing its full efficiency, so using things like solvent F will be both safer and more efficient. In general it is MUCH better to use a mild solvent (even just vegetable oil) but let it wet a long time (5-10mn).

You need a polyurethane adhesive which reacts with humidity to cure and remains flexible. Pick a colour that suits. Bostik is one brand.

MS Polymer glues are an evolution of the polyurethane glues (they also cure with humidity and stay flexible), and are better on all counts for our uses.

To add to Colas comments:
I now have an acetone sensitivity from my racing Cat building days. If I get it on my hands now for any length of time is causes little pusstules around my fingernails, and sometimes makes them fall out. If you uas acteone for anything use appropiate gloves ( ie ones that acetone won't dissolve or penetrate).
Methyl-ethyl-ketone was worse for you, but has pretty much disappeared from the market ( they will tell you it is because it is carcenogenic , which it is, but the real reason is because it is used for making Ice. Unfortunately it is pretty much the only thing that dissolves epoxy, if you need to do that.

Wow, good to know
I shaped over 350 surfboards without a mask or ventilation.
Glassed 150, no mask, and used acetone barehanded on about half.
Lucky I took up taxi cab driving after that.

Gregjet, sorry to hear that.

Sensitivity is a treacherous foe. It often builds slowly under the radar until it is too late, even for seemingly mundane things.
I recently stumbled upon this article:

"You probably have about a 30 percent chance of developing an allergy to whatever it is that you study." While data is limited, that estimate is in line with research on occupational allergies, which studies suggest occur in as many as 44 percent of people who work with laboratory rodents, around 40 percent of veterinarians, and 25 to 60 percent of people who work with insects.

To be fair to acetone, I was getting a LOT on my hands and washing my hands in it to get the resin off.

Could you use a citrus-based cleaner to remove the old adhesive from the deck pad before you applied whatever adhesive to stick the deck pad back down? Im thinking about that for my own board, anybody successfully used it?
