Well, this is what I have to work with. I removed the siding off the wall that I'll be working on. Some of the seams are taped with a dull grey tape that seems to still be holding well, some are taped with duct tape (some of which is falling off), and other seams are not taped at all.
Suggestions?
This gap is at least 1/4". I can see the boards behind the foam.
On the right side here you can see the dull grey tape I mentioned above. It still appears stuck quite well.
