I'm not so sure about the "toughness" of the stealth coating...
I dropped my extended end cap on the floor of my locomotive the other night, maybe a four foot fall at best, and chipped the coating off in a small area. The floor is a some of laminate type flooring, not hard metal or anything.
For something that's supposed to be tough, I didn't imagine it would chip so easy.
Oh well...life goes on. I just say it has some "character" now...
Considering the listing says, "We've made the finish more durable" you might want to contact them. At least just to let them know.
