Okay, I am vintage and own a vintage Rivoli that I bought new. I was reading this wondering why people are leaving their guitars on stands or hanging for weeks or months at a time. I can understand that in a store; but. an individual? Can me strange; but, I only use my guitar stands when I am using my bass guitars or planning on playing them. The rest of the time them stay in their case in a environmentally controlled conditioned space. When they go out, they ride in the passenger compartment of the car, not the trunk. This has resulted in no stand wear, no fading and no cracks in the finishes.
When younger I had lots of my collectable toys and photos hanging out for people to see. I was later shocked to discover how much the air, dirt and UV had effected the goodies. Even the hardshell case is not 100% safe. My brother stored his Fender Jaguar in the case; but, foolishly it wasn't in area that was properly conditioned.
Having seen a friends $3000 Gibson accoustic guitar fall off smaller stand, I switched to Hercules stands more for stability being Nitrocellulose Safe never entered my mind. I haven't checked; but, I think the EB may be the only one with the Nitrocellulose finish and when it is out, it is on the Hercules stand.
