Air Sealing Panelboard?

[Angelfire]

Hiya Folks,
Passed my rough in inspection yesterday with flying colors so thoughts are turning towards insulation. This is for a detached garage. I'm using duct seal on all the exterior and in ceiling boxes but was wondering if there's code against doing so in the panelboards? I was looking to seal where the NMB/SER/etc..enter the panel. Lot's of holes in the panel as well that it would be nice to put a little dab over those as well. Just wondering if there's anything against doing this (it wouldn't surprise me if there is).

Cheers.

i dont see any issue using the duct seal putty on the outside of the panel where the wires enter the panel.

Thanks Wylies! Just wasn't sure if there was some obscure rule that nothing could be added to a panelboard and that would include duct seal. Thanks for the confirmation.
Cheers.
