Salt's a bitch, it is true. As is the saying "rust never sleeps", and it is a true one. The new rino liner and body restproofing works pretty well. My jeep is remarkably sound after several hundred miles on the sand and more than one trip thru saltwater at low tide.....Around here the beaches are quartz , feldspar , garnet, mica and iron oxide sand. Quite fine, too. Fl;a has that nice coral/shell sand that packs nicely and will alow a LIGHT vehicle to drive on it nicely. Here, you need 4wd and a SUBSTANTIAL ground clearance or you're STUCK and more than one has lost their vehicle to rising tides....
