Attached garage air sealing

Our siding contractor will be taping all exterior OSB seams with Siga Wigluv 60. Should we have him skip taping the seams on the garage and just do our air barrier between the garage and living space (on one wall only, no living spaces directly above)? Or should we do the air barrier on all of the exterior AND add an additional barrier between the garage and living spaces?
The garage will not be conditioned. Climate zone 3A/4A. 2001-built home reno.

tjones,
If you are insulating the walls of the garage, then I would air seal them.
We had planned to have purple board on the garage walls since it gets so humid in GA for most of the year. I've seen mold growing on regular paper-faced drywall in people's garages here. Will the purple board trap moisture behind it if we insulate in there as well? Appreciate all suggestions for detailing that wall assembly!
tjones,
I shouldn’t give suggestions for managing moisture in walls in hot/humid climates like yours. I just don’t know enough about them. Hopefully someone with a better understanding will chime in.
