Consider ceramics for guides. They wear like the rock they are, while remaining slicker than the ice after the Zamboni passes. I even use ceramic thrust "bearings" on mine now. Goo-free and I'd have resurfaced my cool blocks a half dozen times and replaced them once in the couple years since the ceramics.
