Update:
We decided to use what dyes and finishes we had on-hand or locally available. Just trying to keep our cost down is all.
Chuck's guitar body is Transtint Dark Vintage Maple and his walnut laminated neck is simply clear coat. Clear finish coat is polyurethane. The finishing on his guitar has started. My neck is clear gloss poly as well but laminated with the Arkansas Black Cherry. Today I applied the color to my guitar body (no pic of it yet) and I used a Transfast Brown Mahogany dye on it. I had several different dyes on-hand and just chose something that I thought we'd both be happy with. And so....the finishing part begins.

So....that's where we stand at this time.

OH.....and BTW.....I've already ordered the hardware and electronics for the coming Telecaster build.
