Sorry guys, i haven't been checking in much of late. I will try to explain it again. When you look from the top down on the metal it looks like this:
Normally you see it from this side so the ribs stick out and the most of the metal lays flat against the framing.
-----------------^-------------------^-----------------^----------------
When you have it reverse rolled the finished side is this side so when you put a bench up against it most of the flat of the panel is at the back of the bench. I put the metal on the walls in August of 1994 and they are still it great shape.
I have tried to attach a picture of the shop, this my first attempt at this, hopefully it works. If you look at the interstate batteries sign you can see how much of it is against the panel. This is the best pic I have of this. The shop is my dad's, he lives in Michigan. I live in Virginia. Hopefully this will help.
knixon804, your shop looks great and think you will really like the metal on the walls. How close is south boardman to kalamazoo?
