Both/Either.

The TSB for a sunroof that refuses to pop up is to lubricate the mechanism AND the sunroof gasket (not the fuzzy part, the rubber seal) with silicone. This did not work for me, and it made the sliding somewhat awful. Lithium grease makes it much quieter and smoother, and turning the sunroof nut until there's barely any slack makes it pop up instantly.

You're welcome.
