Re: Tips for aging the finish on a White Les Paul
I've messed around with the idea before, finding a mixture of coffee and curry powder to be about right. But don't blame me if you make a bunch of yellow patches all over your white guitar! LOL
I've done it with pickguards.....NEVER use hot water, only cold. With a guitar, I'd try brown shoe polish with curry powder sprinkled on it, but try it in an inconspicuous place first. And don't worry about going overboard. At that point, you can take the guitar and put it in direct sunlight, and whatever dying you did will fade into the natural hue you're looking for.
Mostly concern yourself with NOT going too yellow or brown, but a nice cross between them.
I've played around with this stuff before, and it can be done, but you've got to understand that there's a risk in messing up an expensive guitar. It's a learning process, and that's why professional 'relicers' get paid a lot to make a new piece look old. They figured it out with trial and error.
