I have a zodiac 2.6m with a fibreglass bottom.  There is a slow leak from under the fabric of join of the tube to the hull.

 

I have the correct patches and glue etc, but dont think that will do any good, as patching the end of the join will just result in the air leaking past.  Its a slow leak, so I tried unsuccessfully to jam some sika in there.

 

Does anyone have any bright ideas on how to fix?

 

White stuff (sika) in second photo is where air is escaping.

I think the existing seam has to be removed with heat,  leak patched then re glue the seam.

 

Can be done at home but probably better for a pro job if the rib is in great condition otherwise.

Bugger.  Anyone got any suggestion on who might be able to do it?  Is in otherwise good condition, so dont want to stuff it up

Sailors corner have a product, you put it inside the tubes, to seal leaks such as this. Like a wash around internal solution. I haven't used it, it's not cheap. But if it's only a slow leak it may be effective.

Wouldnt use that shmoo, same category tire repair in a can. Might be too late but if you could get a heat gun and very gently heat n’ peel those seams you might be able to syringe some two pot contact into it.
