My local (family owned for over 60 years) hardware store has 4 or 5 different sizes to choose from. If I was not doing a concourse restoration, I would use that stuff & cut it to fit my needs. I'm pretty sure someone makes the "correct" factory type foam but like I said, the hardware store stuff works just as well & no one will see it anyway.
What hardware store foam? The 1" wide stuff? I just got back from Menards they didn't have anything wide enough to cover this door.
Anybody familiar with Reflectix? I do have a partial roll of that here from a past project
