Hi bass people! Let me give you some insight. I already own a couple of P basses but Im building a 3rd one out of parts. Just ordered a "raw" P bass body and neck and I'm planning to do pretty much everything else on my own without a lot of pro tools (no pun intended). I bought some nitro cans for the finish (white primer, black nitro and clear coat, transparent for the body and an extra amber one for the neck). I also bought some boiled linseed oil since i saw some luthiers recommending it for wood conditioning. I'm still not completely sure if Im going to paint black or leave it a natural finish. It will probably depend on how the wood grain looks for me (the parts are yet to arrive). My plan (based on ZERO experience/knowlodge) was to first see if I can slightly darken the wood using some kind of water-based stain, then "finish" the body with the oil first and then depending if I like how the grain looks or not, give it the primer/black/clear coat treatment or going straight for the clear coat. The thing is I'm completely lost on the sandpaper subject. Can you guys guide me on what type and grit of sandpaper to use for before/after all of those stages I mentioned? and also in wich of those stages is necessary to sand. Thanks a lot for the help!!
