Post subject:  Staining and finishing doubts
Keep studiying on how to built the SG i've already commented in other posts here in the forum. I've been trying to find color tones that are close to the mockups I've projected on Photoshop, So i tried several variations between Mahogany (Mogno in portuguese) and Walnut (Nogueira). So, when I found the color tones I enjoyed the most, I started experimenting with finishes like these 3: Birchwood's Tru-Oil, and two brazilian products: Olio Brasile (which is similar to tru-oil, but I found it better) and just a plant-based beeswax called Cera Artifice Supreme. What do you guys think?
Now, my question: I LOVED THE BEESWAX FINISHING. CAN I USE IT ONLY? ARE THERE ANY DOWNSIDES, LIKE STAINS IN MY SHIRT WHEN I PLAY, FOR INSTANCE? :D

Thanks!

You can use wax as a finish, My partner and I did in the 80's when I made my first attempt at lutherie.

Drawbacks:
One way street, no other finish will ever stick after you do this so if you do not like it you are stuck with it.

Does not seal down the wood so splinters and chipping can be a problem with certain woods.

Can have a tacky feel and be grabby against your shirt

Can allow sweat etc through so the wood underneath discolors. Especially at body contact points and certain woods are more susceptible.

I have had success with shellac sticking over 2 coats of Johnson's paste wax. It was not a full finish, just two coats.

Wax is a temporary "finish", in that the sheen and protection is provides oxidizes fairly quickly.

Shellac will stick to wax, yes. But the wax becomes a bridge.... anytime you have a harder finish over a softer one you will eventually have issues. This is due to the softer material moving under the harder film and causing most typically crazing and flaking of the top coat.
