Thanks for the reply, sounds like this is just what I need. While I was good about keeping the rig well waxed for a long time, we've been dealing with health problems for the last couple of years, so the rig has just been mostly in storage-- I run the engine, genset, and systems every month, and drive it 20 or 30 miles at least every every month, but it hasn't had any cosmetic care whatsoever. Since we're in Arizona, there isn't any worry about corrosion, but the (mostly white) finish is fairly dull.
I'm having a new stainless kitchen sink installed as we speak (to replace the original plastic one, that cracked), plus an oil change, new air filter, and anything else else needed to bring things up to snuff. But when I put it up for sale, first impressions are everything, so I'm afraid all of that will be for nothing if I don't get a good gloss on the finish.
I'm not in shape to be doing this sort of thing myself these days, but we've got a couple of industrious kids in the neighborhood looking for odd jobs-- so I figure I'll give them one!
