Masking off clear 3M bra when buffing your car

[Rjscharer]

There was a suggestion offered that I use Meguire's DA paint perfection
system on the hood of my new Cobra. Can anyone suggest the best way
to mask off the seams of the clear paint film edges so as not to damage
the mask when using a buffer? Much thanks.

Maybe create a margin using compund by hand around the clear bra, then power buff the remaining area??
