Well mine is free lol.I picked up a bunch of the stuff when a local hvac company was going out of business .They built big refrig. units for industrial stuff and used the diamond plate on the catwalks on top of the units.I think I got enough left to do my rear panels also.Will post pics when done.
I like the look of that brushed aluminum,I wish this stuff wasnt so hard to cut,its all pretty thick and Im having to cut it with a cut off wheel lol.
