***Major Hypalon patch***Need Help

Hi guys,
Really impressed by this forum and all the useful knowledge and help provided by the professional RIBER'S
However I need some help and advice in doing a major patching job on a Novurania Hypalon, its a u shaped cut 10 cm X 5 cm X 10 cm on the bow
and another one on the same tube 10 cm long
they are not near each other they are about 50 cm away
I know that an inside patch is needed
but its kinda difficult to do the u shaped one as it's located where the fiberglass meet the tube there is a very tiny area where i can stick my hand between them
also the glue i have in my area is the clifton 2 part and the polymarine 2 part
so which one is better ?

As a third option, I believe "sc2000 rema tip top" is available in Your region, also that makes a very strong bond.

This is the u shaped cut, the hole in the fiberglass is for the navigation light pole socket (just in case if you were wondering what the heck is this)

i know that this glue is meant to be used in heavy industrial applications which includes rubber (hypalon) and for sure will be more powerful than the the other recreational glues lol, but will it remain flexible ? and also wondering if you know any directions for reactivation in case of future repairs or anything that might go wrong with this repair ?

Possibly a stitching job followed up by very very large patch?

I've used the Clifton adhesive and it worked fine...no experience with the Polymarine. That doesn't look like an easy patch from what I can tell from the picture - may be difficult to get it done correctly unless you have a lot of experience. Can you remove the tubes to give better access for the repair?

No idea if sc 2000 makes as stronger bond than other hypalon/rubber glues, but I am sure it is strong enough. As for flexibility, would not worry, this glue is also used for gluing conveyor belts so guess it must remain flexible. The reason I used it was mainly due to easy sourcing, otherwise would have used Bostic as it has a good reputation. The bonds are pretty permanent, not much other options than heat and mechanical work to separate them?

Looks like a challenging job.

stitching is good idea though i don't see a lot of people doing it, wondering if you try it before ?
also thought of covering the whole portion of the tube not only patch it
kinda stronger and better looking
