if you do an internet search on nickelplating...i'm sure you will find other services that might be willing to try it on your guitar.
But the ebay ppl are the only ones that i know of with some experience in doing guitar bodies........i don't know how they are turning out nowadays....but their finishes are unpredictable. You can end up with a crappy one, or a fairly decent one. They told me it's different for every guitar. I've seen some horrible ones (the kind where you just want your money back), and then some more better looking ones.
Most of them come back with crappy edges, neck pocket gouges, and all the drilled holes are either filled with metal plating or are not uniform and the parts won't fit. you have to clean all the edges, pockets, holes, routes yourself.....and that can be a pain. They don't do that for you. The one i had done came back with several flaws, there were hills around the edges, gouges in the neck pocket, drips, bubbles, ridges, valleys, ripples in the finish, etc.....Parts didnt fit......and i spent hours just to get them to fit. But i can't get rid of all the ripples, hills, valleys in the finish.......those are there to stay whether i like it or not.
The finish looks good from 5 ft away.......nice and shiny. But don't be expecting anything better than a real Js
Of course, if you are going to play the guitar all the time.....then it won't really matter. When all the parts are fitted, some of the flaws get covered up.....and the overall appearance seems to look better. But from 10 ft away......you won't see the small flaws, and the finish looks pretty sweet........it shines and reflects like chrome. However, the finish is not smooth like a chromeboy..
