Rib patches and repairs

Hi all

Sorry if in the wrong section, but I have found the source of the leak on my rib.
Under the nose protection there are loads of old patches which are leaking.
My question is this.
1. How do you know which is the correct material to match yours (mines a Narwhal old thing)
2. Is it every worth buying a repair kit off ebay.
3. Is there any special tools required to fit the patch (i.e rollers)

It's Hypalon. I've posted a few times how to repair Hypalon patches so I'd do a search. i alos believe there are good instructions on the TIDEL (Paul Tilley) website You need to get the cladding off and repair the patches prperly by removing all tracesd of the old patch and glue.

If you can't find the thread I'll find it for you

cheers stu

If it's a Narwhal it most likely going to be PVC.

The boat is PVC, so you will have fun cleaning the glue off! (not).

Those patches look like someone has tried to repair the seam, quite a lot of the Narwhals are famous for being badly made in the seam department, mainly the earlier ones and if your boat falls in to this category then you could be opening a bit of a Pandoras box!

If I was going to tackle this job I would see whether those patches are on there to stop air leaking out of the seams first. Then if they are I think it is maybe a job for the pros unless you are confident in your rib repair skills. If they are just simple air leaks nothing to do with the seam then there is no reason not to do the job yourself. (I keep putting myself out of a job).

You will need 2 part adhesive and I am not sure this is the stuff you will find on ebay?

Don't hesitate to get in touch if you need more advice.

Cheers

Stephen

Hmmm this rib is starting to become a headache!! lol

Can anyone tell me what 2 part glue I need, where I can get PVC repair strips and possibly a link to a patch repair thread.
