Apartment owner can get an OLD roll of heavy inlaid Solarian for cheap, but if the seam can't be done properly, I don't want him to buy it. There'a a 9 foot seam in the middle of the kitchen and probably a short and narrow one under the fridge. The roll is old, but it feels like new.... then felt hasn't hardened up and it still feels pliable.............. well, as pliable as Solarian ever got. My brother mentioned Supermend epoxy, but I don't know it's set time and spreadability. S-200 was predictable. I miss the old days.
