Sealing a leaky inflatable

[superheat6k]

I know there is a compound available from the chandlers that can add a liquid sealant to the inside of the air chambers, but is there anything non nautical that can achieve the same task (also cheaper) ?

lots of gunky systems for motorbike tyres, e.g

http://www.oko.com/contact/

but the environment in a tyre is different from in an inflatable. Much more movement, wider temp range, and materials which are not the same as the rubber/poly of tyres.

Worth giving OKO a call ? They are a not far from me, so I can go down and chat if you want ?


And a more heavy duty stuff

EDIT

Just seen this stuff for dinghies.

Sealskin from Ribstore via eBay worked for me. PVA?

H&S information: the motorcycle repair works by centrifuging onto the interior of the tyre, so be sure to let the missus out before you spin up the inflatable.

I have used a US product called Slime. It is bright green!

Gave me an extra 18 months on a dink that had leaky seams.

Pour it in, inflate dink and roll the dink over to distribute it.

In the USA the price varied a lot with the truck stops being much cheaper than the Ducati dealership. Same Slime I am told.

I've heard that PVA adhesive does the job, though I've never tried it.

I think that distributing a sealant evenly around the inside of an inflatable would be fairly difficult. I had an old Avon which went soft after 2-3 days, I painted it with Polymarine Hypalon Paint, really for cosmetic reasons, and was surprised at the improvement in air-tightness, but not particularly cheap these days.
