To start, I'm a total newbie to refinishing etc. I've had it in my head for months now to strip the cherry poly finish off of my old Epiphone EB0 and refinish it with a can of Northwest Guitars Nitro white lacquer. It'll just be a fun project and I don't really need to worry about ruining the bass, as I've since upgraded to a Gibson EB3, as well as a couple of other basses. I want to get started. I bought a big tub of multi-purpose wood grain filler back in February. However, I am not sure whether this is necessary. If I were to sand off the finish down to the wood, do I still need to apply the grain filler after? I've heard some people say no you don't need it, and some say that you do need it. I want a gloss finish at the end. Hoping some clever folks in here can give me some guidance. TIA!
