Has anyone, ever thought about getting their everyday commute handlebars
hit with some spray on bedliner?
would that be superior to replacing grips?
Would it better gription?
Would it stay in the neck more sturdily?
Should I repeat 4th grade grammer?

No, I haven't.
Maybe.
I don't know.
Couldn't say.
Not entirely convinced you took it the first time.

J/K. Seriously though. I've got ODI signature grips on four bikes, and three are riders. I'm thinking that when the mushroom rubber part is dead and beyond using, I'll keep the white/hard plasticy base, and replace the soft grip with this stuff from work.
It's cold-shrink. Good for putting grips on hammer or rake or shovel handles and whatnot. Black, rubbery but very durable. Or splicing sprinkler system PVC that accidentally got hit with a backhoe. We actually use it on High Voltage terminators to keep water out of the cable jacket.

I think I'll try some of it elsewhere on my bike as kinda an experiment, take pix and I'll let you know how it works out.

cool...
