Narwhal rib repair - Who or what to use

I need to repair or have repaired an unstuck seem and two rope holders on a Narwhal NR240 tender. Apparently Narwhal ribs are not made anymore and I need to find out what it is made of - PU, Hyperlon or other. And then should adhesive be Bostik 2402 or 3206. It came with a pepair kit but I tried the one part glue in the kit and it was useless.

Can anyone please help?

My Narwhal is PU or Hypatext as they call it.

Suitable two part glue and patches are available mail order from IBS.

Also may be worth getting some MEK solvent to clean the area prior to sticking. (be aware that it is hazardous stuff though).

Cheers

Mike

Ribnot,

Apologies just re-read my reply - Material is not PU it is PVC!!!

Need to put brain in gear before typing !

Can vouch (sure thats not how you spell it) for jwalker's method 100%.

Used last year to join partially separating tube - boat has taken some punishment since but repair is sound as the day it was done.

Absolutely essential. It's NOT a cleaning agent. It expands the pvc to let the adhesive in and it is necessary for wiping the surfaces prior to bringing them into contact.

------------------------

Thanks Mike B. I'm pleased you are happy with the method.

-------------------------
Can I make a wee plea here. If anyone follows advice given in a ribnet post, it would be useful to have a report back as to the success/failure/results. That way we can all learn without having to do it ourselves.
There is a huge amount of information on the site but, mainly, it is only those who have tested it who know whether it is good info.

Ta, in advance.
