Best adhesive to re attach keel guard?

Last 18" of keel guard has come away. What product would any of you suggest to re stick it with?
What's still in place (90% of its length) seems well and truly stuck on, so I was just going to repair as needed.

Whichever 2 part adhesive is suitable for the material (hypalon or PVC) or if both you may need to prime one side and use both types.

Sorry. Should have explained. The keel guard is rubber (or whatever keel guard is? "Special blend of polymers") and it's bonded to gel coat.

Sika Flex 291 adheres to GRP & rubber, has flex aswell as being an adhesive and is used to seal the edges of KeelGuard & KeelShield in hard use applications already, so should be ideal. Be sure to get rid of all the old grey adhesive foam and flatten before applying (would be my suggestion), then duct tape or similar to hold in place whilst curing.

Been there, done that.... Peeled back a section on survey, and successfully reattached with sika . Give it a good clean down, and I lightly abraded the surfaces too..... Used timber and a trolley jack to ensure good even pressure during the cure

After getting of the old glue (from the keel guard and the Keel) a scotch pad is best to scuff up the keel and then some acetone to clean the dust off and degrease.

See... I knew you guys would come up with something I hadn't even considered. Trolley jack to keep under pressure while curing. Quality! Thanks for replies.

Personally I would go for Bostik 2402 but 3M 4200 or 5200 Marine adhesives have been suggested elsewhere for the same job.

Sika 291 is supurb for this! Also for repairing small scratches in a keelguard.
Simson MSR CA will do the job too..
