Thanks, Vern! I knew about the use (temporary, I think I read, due to availability) of crushed basalt last winter. I didn't know that the red cinders had become an air pollution issue. Bend is pretty dusty. Okay, back to the magnesium chloride and my Vanagon. My OP was about a salty powder/crust found on the windshield lower inner rubber. Kim Brennan kindly offered the suggestion that it might be a road salt which had been possibly drawn in through the dash defrost vents, condensed on the inside of the glass, and then melted down onto the rubber. It makes sense. Vern: have you also seen this in your van? http://picasaweb.google.com/j.michael.elliott/Vanagon# And others who live in road salt environments: Kim proposed that if I'm finding salt there, it will be found elsewhere in the van, too, in places I might not wish it was. Can someone recommend a place where a fellow who is presently not allowed to use one leg look for salt buildup to check this? -- Mike "Rocket J Squirrel" Elliott 84 Westfalia: Mellow Yellow ("The Electrical Banana") 74 Utility Trailer.
