Prosoco Cat 5 vs. peel-and-stick tape
For exterior OSB joints. Is it better to use the Prosoco Joint Filler caulk/compound or just use peel & stick tape? Which will last longer?
Prosoco is supposedly breathable so it allows moisture to dry. Any feedback in the field?

Peter,
Here are links to two articles I wrote on liquid-applied flashing products:

Personally, I think the easiest approach to sealing OSB sheathing seams is to use a tape like Siga Wigluv, 3M All Weather Flashing tape, or Zip system tape. But other GBA readers may have a different opinion.
