Useful information, everyone.
Please keep it coming.
If you read what I wrote earlier, I don't like the current fad of over-aging guitars either. At the same time, I built a replica of a late 1968 - early 1969 Strat from a mishmash of vintage, Fender, boutique and homemade parts.
To leave everything looking brand-spanking new doesn't look like a 1969 Strat to me, at least none I've ever seen. The process is also useful in understanding how a guitar changes over time and what causes those changes. Finally, I like having a guitar that I am free to monkey with, without costing myself $1000 in resale value by unsoldering a pickup. YMMV. Remember, I'm not asking you to age your guitars.
In the meantime, I experiment and play on this guitar, so it collects wear that way, too.
I have a feeling that professional furniture restorers may hiding some useful information. They've been doing something similar to this for decades.
