I recently ordered some but it came to me with a pinhole in the package. I planned to just have it in storage for when I need to replace but with it open it won’t have a very long shelf life. BRS sent me a vacuum sealed replacement, so I don’t need the open one. Any supporting member can have the open package for free. If you have a vacuum sealer, you may be able to reseal it and be good to go...I dunno. I’m not sure how long it’s good for being open, but I’m sure someone can use it. I’ll be at CFM until 2 or you can stop by my place e anytime in fremont.
