The belt wrap is something aftermarket that I have on my supercharger to help prevent belt slip with smaller pulleys, something I'm assuming your car probably doesn't need yet lol. I wanted to help and take pictures, but unfortunately I can't just take it off that easily, and I also didn't want to confuse you. Basically don't mind my belt wrap, just pretend it isn't there
The anaerobic sealer goes on the mating surface where the snout meets the rest of the supercharger. Once you pull it apart you'll see what we're talking about. It's just like any other gasket surface, make sure to clean any leftover residue/gunk that may cause an improper seal.
