I think mine are still in the bed of my pickup buried under a foot of snow and ice. I'm on six years now with my 5000's, they are rusted to all hell and they still work fine, including the buckles.

serioulsy though, thanks for the info guys, I didn't even think of using a never-sieze on the korkers. I've got one korker done with the SS screws via the DZ method and now I'm going to have to get some never-sieze and finish the other.
