Here's what I did to my Mockingbird.
Just traced out the pattern, glued all the pieces down, and went nuts with the clear coat.

Took a while because paper doesn't work well going from a flat face to a curved edge.

Heavy coats of gloss to try and get it to look like porcelain.

One of the easier bits to do.

And done... I guess.

There's still a lot of wallpaper...
Might not work out too good with Fenders and all the contours (unless you're super patient), but a cheapo acoustic or something with sharp edges should be really easy to do if any this appeals to you.
