You don't even wanna see the bottom of my resto XP800. I looked everywhere for factory gel and I think I found the yellow but it was crazy expensive and then the magenta is not possible to fine (maybe racer can find it?)
I ended up just patching the bad areas (exposed fiberglass) by mixing my own gel and doing my best to color match it. None of my skis ever have damage on the bottom so it ate me up knowing it was there, but at this point its an out of sight out of mind kinda thing. I spent a lot of time and research agonizing over it but reason ended up winning. On the bright side because of it its the one and only ski I will beach! haha
