I am starting to wrap my metal building. Sheets come together on the
corners, and I will use 6" x 6" x 10' 90 degree 26 ga, paintlock flashings.
In some places, it will be advantageous to add a caulk of some form, but for
larger spaces than a normal caulk bead.

Can I use a string of Good Stuff, and just let it expand? Will it adhere to
just the flat surfaces in the 90? If you use it to fill up the ridges on
the corrugated sheets, would one just spray a little in there, let it
expand, spray a little more until it filled the area?

What I want is to cut down on air flow/infiltration/outflow so that inside
air stays in, and outside stays out, and there aren't a lot of drafts.
Other areas around the doors will be handled with bulb gaskets, etc.

Just wondering how that stuff works in other than voids where it expands to
fill the void. Does it stick when applied overhead, or on a vertical
surface? I may have to make cardboard dams to stop a lot flowing out before
it hardens and skins over.

Anyone ever use this stuff in that application, or have an alternative?

Steve, I know several commercial contractors that use one of the
expanding foams on hollow metal jamb work to maintain a screw pocket
around fasteners to prevent mortar blocking the holes when the jambs are
slushed, so, yes, the stuff sticks. It is very awkward to control.

As far as sealing anything about metal building joints, the normal
product to use is called "bubble gum". It is strips of butyl rubber
like this:

It is commonly used on roofing laps and gable end trim/gutter installs.

YOur trim supplier should know about and be able to supply.
