I bought a '65 Teisco for $100 and I was planning on re-staining it. The stain/cheap paint stuff on the neck is in bad shape, and the body has dozens of knicks and scratches in it, but I like the sunburst finish (I think it's actually called tobacco sunburst). It's a gold color in the middle, then fades out to a brownish-red then to a black. If i had a picture right now it would probably help more. But my question is: would it be hard for me to replicate the original finish myself? What would I have to do to get started? How would I actually make it fade? Also, I was talking to this guy working on becoming a luthier, and he said that for a sealant/varnish on the bass that I couldn't use polyurethane. He tried it once on a bolt-on and the neck got permanently stuck after he put it back on. What would be a good sealant instead of that? Thanks.
