Yah I would have to agree, I don't need more upkeep unless there were substantial benefits for it. Thats why I posed the question. You read all this stuff on the web about products. It good to see what other people think.
I never shy away from beaching my boat and allot of times the shore is pretty rocky so I have always wanted to do the Keel guard, but adhesion had always been an issue from what I'd heard. I received a pm from a member who had a strip of Linex sprayed on, it took 2 attempts but seems to be working.
