E93 detailing - Roof Tips and tricks?

Pretty soon I'll be claying and polishing my new-to-me E93 for the first time. I've searched (unsuccessfully) for answers to the following, sorry if I've missed something obvious.

How to handle the rubber seals between the roof panels and the painted plastic strips and channels underneath? Tape off the strips when using a DA polisher on the roof panels and avoided the rubber seals, or just polish right over them?

I'd think the former would be the "right" way to do it, but am curious to the experts thoughts.

Also, how about all the intricate curves on the nose; even 4" pads seems pretty big for those details.

Thanks.
