I traded two boxes of this stuff to Crows Nest Nautical over in Stuart, Fl. It's the real stuff, 3/8 x 1" x 5 1/2, coming from the same Mfg. Krogen used at the yard. I think there was about 35 sq ft per box so there should be about 70 sq ft.. Easy enough to ship but heavy. Here's the contact info. Talk to Mike.
