how to fix slow air loss in rib inflatable

[Branko Mladichek]

I have a Grand 3.3 m rib inflatable with hypalon tubes. I have a very slow air loss from the tubes. I have tried throwing soapy water over it but can't locate where its leaking. I am thinking of using tyre inflator to coat inside. Is that a good option or is anything elseIMG_9927.jpg a better choice?

Same way you find a leak in an air bed. Soapy water and move all over it you will find that it probably will be on a spot that only opens up when there is pressure on it..
