What I hate with these things it's that'it is unpredictable, especially with guitar stands.
BTW, I've seen horrible things with guitars that have been stored in cases with cut out foam. So that's predictable: don't ever do that
I check my guitars I think once a year. I have some on mounts hanging on the wall and some on guitar stands. I use K&M for my single stands and hangers. Never saw any damage. As a Yamaha collector I dont think any of my guitars has a nitro finish, but the one nitro guitar I have stays OK on K&M stands.
Always used Rockstand for my multiple stands. I have about 4 or 5 I think. Used them for years, never any problem. Bought one some time ago, had some acoustics on it for a few months, and some show laquer damage, also the poly finished
I think only a few kinds of lacquer is used on guitars. Why is it so difficult to make stands where they guarantee there is no damage over time?
