Hello,
I'm about to start finishing my first guitar, a blanca flamenco, and I want to make sure I'm not going to do anything stupid

.
So, my back and sides are made of cypress, which is a non-porous hardwood, so no filling is needed. The bindings are rosewood though, so I got to fill them. Should I just apply the filler to the bindings, or do the whole back and sides + the bindings and sand them down? Otherwise, I'm wondering how to apply a thin even coat of Z-Poxy only to the bindings without dripping on to the sides or whatever might happen.
Then, I got to fill my Spanish Cedar neck and headstock rosewood veneer... how do I do that with a credit card as mentionned by some?
Also, I decided to give KTM9 a try instead of FPing... is 99.9% methyl hydrate alcohol alright to thin the finish and Z-Poxy? What ratios should I use?
Best Regards,
