I see alot of people using UHMW for skidplates and stuff like that, but what about PTFE (teflon)?
I need to build a skid plate the gas tank on my 4runner, and due to a last minute design change, we're scrapping some small sheets of 3/8" thick PTFE here at work. Would this material work to skin the gas tank skid frame? It sounds like it should slide good, but I'm not sure how it may hold up to impacts
