So, I have sort of an odd question - I need a coating (or something) that will increase the friction on a CPVC pipe as much as possible.
Specifically, I rigged some CPVC pipe to mount a light from my bicycle rack (I am a commuter.)
However, the PVC pipe is apparently not a standard size of bicycle tubing, and even as tight as I can get it the light tends to slide around a bit.
Would some sort of rubberized coating work?
(I suppose I could put some inntertube on there, but I suspect stretching it tightly reduces the friction if provides.)
