Will a vinegar/water solution also take care of iron deposits? I was bequeathed my grandfather's boat, which spent a lot of time simply floating in an iron-stained lake in northern Minnesota. It has a pretty good rim of red where the water line is. Not a big deal, but it would be nice to scrub it down and throw a coat of wax on there before this open-water season.
On that note, what sort of wax/finish do people recommend? And is it as simple as wax-on, wax-off? I think I've waxed a vehicle once in my entire life, and it was a 1994 Geo Prizm. I'm a noob to the ways of boat beautification.
