Roof clean with Mop n Glo

[BILLYBOB1941]

I heard this is a good way to seal the roof. Anyone out there have experience with Mop n Glo?

Not sure what you mean by "seal".
Coating your roof with Mop n Glo help the dirt wash off easier later, and makes it shiny, but it doesn't help with leaks (the usual meaning of seal).

Neither EDPM nor TPO roofs need to be sealed and don't benefit from it.

EDPM is notoriously sensitive to solvents of any kind, and the only reason for washing it is to remove the dirt and loose binder material that makes the black streaks down the RV sides. EDPM is UV stable and needs no additional coatings for that either.

TPO was introduced in the mid 90's and doesn't even shed binder material like EDPM so the only reason for washing it is pride.
