Hi everyone, I bought an old neck off eBay for a project I have going and am looking for some advice on cleaning it up. The seller thought the neck was a '72, but it is hard to confirm because the neck stamp is that weird green 7 digit code that has never been conclusively deciphered, as far as I know. It does have two string trees, but from what I've read Fender quit using that neck code system by '72, and a lot of people think these were only used in '69. The code is 3 22 017 B. The neck was painted black. I am in the process of removing the paint and would like to know what I need to after I get all of the paint off. I have only used 320 and 400 grit sandpaper for this because I didn't want to sand into the wood. This has taken a lot of time because I am doing it by hand, but has done a pretty good job removing paint only. I even exposed a F71 stamp and a handwritten "C" on the heel that I guess are under the original finish, and some old green finish from a former body. I'm not sure if there is any original finish on the back of the neck, it doesn't feel like it. I think the refinisher removed the OG finish before it was sprayed black. There is also some primer or something along the top side that has been a real bear to remove, much more so than the paint. My questions are: Once I have the paint and primer completely removed should I continue using finer grades of sandpaper on it, or can I stop with the 400? Do I need to put anything on the back to seal the wood pores and protect the wood, and should I eventually have a clear coat sprayed on the back? What is the best way to clean the maple fretboard? It has a nice amber look, so I just want to clean it up and remove the crap from sanding and the bit of black that got on it. Would using Naptha or 0000 steel wool be best? Please give me,your thoughts on this. Thank you all in advance, many pictures to follow.
