I'll be upfront about something: there is no fast version of what I do. The aging on a Mestric guitar takes longer than the build itself in many cases, and I've never found a way to meaningfully speed it up without the result looking like I tried to speed it up.
That's not a complaint. It's just the nature of trying to replicate something that, in the real world, took decades.
A Technique Worth Understanding
One approach I've seen used by some high-end builders involves applying vinyl stickers to a body before painting. The areas beneath the stickers remain bare; once the finish is applied and the stickers are peeled away, those exposed zones give you a headstart on the aging process. It's a particularly useful technique when you're producing a run of guitars intended to replicate the specific wear pattern of a well-known instrument — a celebrity's guitar, say — and you need that pattern to be consistent across multiple builds.
It's a legitimate tool in certain contexts. But for what I'm trying to do, it introduces a problem I can't get past: stickers leave edges. And real wear doesn't have edges. It has gradients — places where the finish thins and crazes and fades in the way that material does when it's been slowly compromised by years of contact and chemistry, not masked off and removed. To my eye, at least, the difference is visible.
I'm sure there are players who wouldn't notice. I notice, and I can't un-notice it, which makes it difficult to use that approach myself.
What I'm Actually Trying to Achieve
The areas of a Mestric finish I'm happiest with are the ones where the lacquer looks less like it's been distressed and more like it's been lived in. There's a particular quality to finish that has been slowly broken down by the acidity of a player's sweat and the repeated exposure to moisture — where the nitrocellulose hasn't been scraped away but has genuinely degraded over time. Getting that quality right, or close to right, is something I've spent years working on.
I won't go into the specifics of how I do it — partly because the process is something I've developed through a lot of trial and error, and partly because honestly, I'm still refining it. Every build teaches me something.
The Reference Library
Over the years, I've had the opportunity to examine a lot of vintage instruments firsthand — initially through running Port Mac Guitars, and more deliberately as I've developed Mestric. There's something about handling an original from the 1950s or '60s that photographs don't quite capture. The way a finish behaves at an edge versus a flat surface, the depth of wear around a pickguard's edge, the particular way lacquer crazes at the heel — these things are genuinely instructive to observe in person.
I've also built up a photographic library of highly worn vintage guitars that I refer to regularly while I'm working. Good light, multiple angles, high resolution. It serves as a kind of ongoing sanity check — a way of asking myself whether what I'm producing actually resembles what decades of real use looks like, or whether I've started to drift toward something that only looks convincing if you squint.
The honest answer is that it's a moving target. My understanding of what vintage wear looks like keeps evolving as I encounter more instruments, and I expect that's how it will always be.
The Practical Upshot
None of this is to say that guitars built using faster methods aren't genuinely good instruments — many of them are. I'm not in a position to build at volume anyway, so the approach I take is partly a function of circumstance as much as philosophy.
What I can say is that when I finish a guitar and hold it at arm's length, I'm looking for something specific: a finish that looks like it has a history, not a finish that looks like someone tried to give it one. Whether I fully achieve that on every build is something I'm probably not the best judge of. But it's what I'm aiming for, and it's why I haven't found a shorter route that satisfies me.
