porosity maybe ?

[wolfie]

thinking my old tubes might a bit on the porous side ( new ones next year once i get the readies together :-) )
meanwhile has anyone used polymarine sealflex ? any good ? better alternatives ?

thanks in advance

Yes it works ok.

It finds a leak and seals it. Thats ok if the leaks at the cones or the lower part of the tubes where you can get the sealer to. If your leaks in the middle of the tubes, on the top its not ideal. The sealers probably best on SIBS where you can roll it about and cover a greater area
