It thought I would try velcro for the plastic golf club tubes (i've since reconsidered that whole proposition). I used the industrial strength velcro and mine didn't adhere very well. Quite likely I had a film of some sort on my boat or maybe it doesn't do well with carbon fiber. Not sure what happened but mine peeled off on the first trip.

Soooo........A person may consider a mild solvent like paint thinner to clean the surfaces. Just sayin.
