Tracing a leak in one of the three sections of my inflatable has been unsucessful.
Has anyone ever considered using or better still used "Tyreweld", the roadside puncture product to fix an inflatable for a season?
Regards

yes - and no.
Not tyreweld, but other things...
I used chlorinated rubber paint which I had in stock on an old dinghy, and it immediately showed a porous area, but was not really a long-term fix. The dinghy was scrapped.
I have successfully used dilute 'deco-elast'* on a tyre puncture -long term fix, and silicone bath sealant on a burst fender, again long-term fix.
If I'd had deco-elast at the time, I'm sure it would have fixed the dink.
All were introduced to the inside, the object rotated to bring the leak into contact, and left, gradually gently inflating to force the liquid into the damaged area.
* deco-elast is a watersoluble rubber solution used for waterproofing roofs (used on the continent.) It can be diluted to flow easily, or applied (as supplied) like custard. It can proof canvas, seal windows, creep into cracks, and is very cheap to buy, if you can find it.
If not, get a friend to bring some home as a holiday gift....

I used a product called Slime a few years ago on an old dinghy that was starting to leak along the seams. It gave it an extra 18 months of life and maybe could have been repeated, It is widely available in the US don't know about the UK.

i used an illuminous green one maybe 'slime' for tubeless tyres in my rear suspension bag on a landrover td5 and still going strong 5 years later.cannot see any reason not to try but a lot of surface area in a dinghy so may need more than 1 pot.

I have a friend who keeps his boat in Marti Marina. Someone there had a large but rather porous rib type dinghy. The man bought the sealant and enlisted the help of my friend to turn the heavy dinghy to distribute the sealant. The dinghy was fully pumped up and left on the pontoon as the sun went down. The following morning the owner was delighted to find it still fully inflated. and left it in the Turkish sun. An hour or two later he was still admiring it, when it exploded, bursting a seam because the sun had heated the air inside.

You have been warned, small leaks in an old dinghy are a bit of a safety valve.
