The concern is that paint adhesion on the outside can be adversely
affected by moisture migrating through from the inside. This is a
definite problem with masonry, solid wood and plywood. I'm not sure
about OSB as it may contain enough glue to block moisture. Better to
seal it while the opportunity is available than to be frequently
scraping/repainting the outside.

Standard "exterior" grade OSB will not likely transfer any moisture.

"will not likely" - "remote possibility".

There is a one in a million chance, you know what that means?
Yes, it happens 9 out of 10 times.

Actually...exterior grade OSB is pretty much waterproof. That being
said..Id not use it on boat hull without a layer of fiberglass..but
for normal humidity in the PNW..Id not consider it to be a sponge.

Tain't the humidity, its the rain. (once it resumes)
