i have used clear silicone adhesive in the "cheeze wizz" tubes before with success. it has to be the "adhesive" stuff, not the regular "sealant". any excess that squeezes out is easily trimmed after curing. i have used this stuff for many different attachment purposes on unlike materials, and have had great results. it is also water proof, and works great in submerged applications [after curing of course, before being submerged]too ! hope this may help.
