I wish my wife was that dirty. Looks like it's been near the beach? How do u tell the bottom mdf is too far gone? (.eg. experience, u can push yr finger through it, other...)?
you can generally see where it has swollen in patches and these are almost impossible to sand out nicely. Some bases also get a bit of a bow in them. The rear of the headbox was pretty good bit there was one streak where water must have splashed and sat when the headbox was down, so i replaced it.
Got the cab and headbox all bogged, sanded and primed today. Will throw a few pics up later
