The problem with that is that Great Stuff *requires* moisture in the air to set. If you take the panel off after a time, you will find a layer of solid great stuff with a horrible liquid center. Previous threads have discussed whether or not the liquid was corrosive.

In my own experience, I have learned that Great Stuff does /not/ set or behave right in thick or enclosed areas. Makes a terrible mess.

Yeah. Daptex is appalling garbage. Wrecked paint, dribbled and after it set, blew away as a powder.

Great stuff is a bit better. I've put Styrofoam behind the panel so I'm trying to fill the gaps. If the great stuff doesn't work, I won't buy more.

I'm almost finished with the internal construction. Been fighting a cupboard door all day!

Don't do it like that! There is moisture in GS and it will cause trouble, plus there's probably already bs like fiberglass n **** that will mess it up. If you want insulation in there, you're gonna have to take off the skins.

No fibreglass. One side is an aluminum panel I'd installed earlier. The othger side is a heavily painted galvanised steel panel I also installed. There is some breathing space there. I'm not greatly impressed by great stuff.

What Tango said about Great Stuff needing air to cure is true. It works good to seal up exposed cracks but isn't good for back filling hollow areas. I call it "So So Stuff".

Drifting a bit, While serving as Range Master at the local Police Academy, One of the instructors got aggravated because the Cadets kept spilling the sand out of the weapon clearing tubes when they set them up. He "solved" the problem one lunch hour by topping off the upper third of the clearing tubes with Great Stuff so the sand wouldn't spill out. Needless to say, when the Cadets came back from lunch and loaded their weapons, not a one spotted the gooey foam in the tube and like good little Cadets did what they had been taught to do--end of range day. That particular Commander has since retired and now is a member of the City Council. Just figures.

I'm hoping it's going to dry. If not, no matter. I'm not buying any more of it.

Just to add to the previous post the guy over on the Wanderlodge
Owners Group used the great-stuff in his kick panels on his Dodge
pickup and in 18 months is now looking for a new cab for the truck.
The great-stuff caused all the enclosed places it was installed to
rust thru in the Florida humidity. He was trying to cut down cab noise.
