I'm sort of relicing my 60th Ann P.
What I mean is that while I'm not being aggressive with it like sanding or dipping metal parts in acid or whatever, I'm doing other things to speed the aging process along.
Like for instance, leaving it on a stand where it'll get sunlight while not playing it (which isn't that often, really), or "accidentally" leaving it in the cold garage overnight and bringing it inside to the warm in the morning. A few finish checks happened from this, but they wiped right off with light finger pressure (seriously, I've got video).
The body gets dinged up because its never in the case, and is yellowing slightly from its tanning sessions. So I'm relicing it, since its all wear and tear that happened without leaving the house, but it's happening naturally as well, just faster and more controlled.
