Topcoat Update:
So I elected to go with the wipe-on Poly finish after kicking around gloss vs. satin.
I decided to put on 4-5 liberal coats of poly over the course of about 5 hours. I know conventional time spacing dictates to usually wait longer, but the room was warm and the wood was very porous so it sucked up the finish quick. Besides, I really wanted 'one good coat' (in my mind at least) so I didn't want to put a ton of poly on over the course of days.
I let the body dry for about ~36 hours then I hit it lightly with 320, steel wool, 1000, then a little bit of wax.
Overall: B-
For my first go around with this I'm very pleased and I think I've just triggered the beginning of a new hobby. I'm really happy with the smoothness and texture of the finish. I didn't expect it to come out as good as it did!
As for as things I would probably do differently in the future:
I would go back with the 120 and hit get the surface scratches on the back out. They don't bother me in the slightest now, but strictly from a quality standpoint this would probably be a better look.
I would also likely elect to use a much darker stain. The current stain is nice but it is too similar in color to the maple neck. I'm glad I ordered black/cream accents since they will help break up the monotony of 'plain wood'.
I would also like to experiment with mixing in oil paints and using the 'cardboard bursting' method I've seen referenced here. I think artist's oil paints make for some really cool color possibilities, and I think the cardboard bursting is a very practical method to achieve a 'more difficult' finish.
I'll keep you guys posted - thanks for the interest and support!
