Warmoth parts fit Warmoth parts, it's that simple. You will not successfully mate Warmoth with Fender without a wee bit of modification first. Here's my Tumblr blog, just scroll down and you'll find posts on my Sonic Blue PBass build which has some relevance here. Please ignore my other ramblings. Or don't.
Here's what it's for. I spontaneously started sanding the finish off a '74 body I bought from the Bay. The existing red tort looks good, but I'm going tung oil/natural finish with black guard (rosewood board - '96 Fender neck).
It wasn't a great sunburst, had no good looking wear, and a bunch of gunk on it.
Great to experience this process that I've only read about. Is that yellow the fullerplast/poly primer? I know that I might THINK I've sanded down to bare wood, but I might find out (at a bad time - when refinishing) that there's still coat on it.
