In my research for all things (actually just fabric) fire retardant (but only with a certificate of compliance with local and state laws, please) I have run across some very odd companies.  Take, for instance, Forever Preserved, which I am pretty sure preserves palm trees and other shrubs so that they look real, but have been coated in something that stops decay.  This immediately made me think: Well, this is likely for pet palm trees. “Good bye, old friend” as you run your hand over the rough bark, and then it’s off to be dipped.
