I have use structured belts as well such as the Norax so I don't see why Gator belts wouldn't work? Mostly you want belts with a cloth backing. Paper will cause problems when wet.
I used a 3 to 1 of water to Accucool and put it in an old windex pump plastic bottle. It makes a mess! lol.
You may want to put a fender/mudflap on the drive wheel of your grinder. Others have built a Gutter trough along the bottom that use constant drip system.
