stldhdh2o, take a look at the new Willie in my Avatar. I Sharkhided it the day I got it. I also used Sharkhide on my old Willie. The stuff works awesome. I was very skeptical when the guys at Willie recommended it. After asking around everyone told me this was the stuff to use. The nice thing is, if it ever did discolor, you can wipe it off with laquer thinner and re-apply. On my old Willie I scotch-brite padded it about once a year before discovering this stuff. No labor from then on and the boat stays looking shiny new!
