I am looking for a liquid latex (or similar) glue that I can spray into tubes using my hand weed pressure bottle sprayer - it sprays a perfect even round fan and I can insert it thru the valve hole .. esp if i extend the rod - I can pretty mush get it all the way down the pontoons -
I cant fill the tubes and roll the boat - it weighs too much! any recommendations?
I had a similar problem with an old RIB. First identify exactly where the leak is, in my case it was under the tape that seals the seam. Using a hill, blocks, the trailer jockey wheel or some strong friends (I am assuming it is on a trailer?) get the area directly under the leak flat. Buy some thin tubing, I used the stuff they use for fish tanks, it will fit over the nozzle of the Latex bottle.
Deflate the tube, you may need to also deflate the sections either side of the leaking section, so that you can push the leaking area down and touch the bottom of the inside of the tube (hope that makes sense!!). Then feed the tube in through the valve, takes a bit of fiddling but with patience you can direct it, to exactly below the leak, squeeze the latex in so that whilst pushing the tube together you can feel the pool of liquid. Remove the tubing, "massage" the tube so that the inside of the leaking area is doused in the latex then pump up as quickly as you can. When I did it the latex bubbled out of the leak.
Worked for me and I managed to get another 2 seasons out of the tubes before the inevitable re-tube. The first attempt slowed the leaks significantly, did it a second time which stopped the leaks totally.
