I always find the over-the-top beating things up with hammers and chains or dragging it behind a truck (I've seen that trick used on a guitar in a video once - no idea why) absolutely ridiculous. Particularly when it's done by someone with more enthusiasm than skill - if you don't look at how a piece honestly wears, you just end up with something that looks like it was beat up needlessly and not something that has honest wear. I still think it's a little silly at times, but when someone with a good eye and some foresight does it, it actually can be pretty convincing. I remember seeing a lady on one of those HGTV type shows make a mantle out a piece of oak and then show the homeowner how to hit it with a hammer before applying a gel stain and then rubbing shoe polish on it to make it look "antique" and "distressed". It was tacky as all heck.
The funniest one are the "pre-aged" electric guitars in the lower price brackets that they offer now. The wear applied to paint and the fretboard isn't terrible looking, and i suppose with modern poly finishes, it's the only way you'll get your guitar to have that look if it's what you want, but it's pretty poorly executed versus one "pre-aged" by hand. But when I first started seeing the lower end Fender Squier's with that faux finish, done by machine, I assume, it was hilarious because they'd have six guitars in a row at the guitar shop, all in different colors, but everyone was worn exactly the same. . . .
