There has been an on-again-off-again debate about the advantages of PVC & Hypalon for years. PVC (as used in your Quicksilver) has a number of advantages. One disadvantage (that the backers of Hypalon) attribute to PVC is that it is less resistant to UV light. One of the symptoms of destabilization of the (surface) fabric is the stickiness you describe. Is it only on the top of the tubes, i.e. most exposed to the sun? There is a UV protectant spray for inflatables that you may want to try. It may help stabilize the PVC, if that is indeed the problem. I''ll look for its brand name and post if I find it.
