Anyone familiar with the Weathershield car cover? Here's an excerpt from the Griot's Garage web site:
A WEATHERSHIELD™, NON-BULKY FOR PROTECTION FROM ACID RAIN AND INTENSE SUNLIGHT
This is the latest generation of car cover fabrics. Its water-shedding technology is the same breathable fabric used in waterproof hiking outerwear. There is no outside lamination or waterproof coating to wear off. The fabric is spun from polyester and the fibers are fully encapsulated to be waterproof. Water just sheets off. Take it off after a rain storm, give it a quick shake, and the remaining moisture will dry off within minutes. This cover is more compact than other waterproof covers and fits easily into any washer and dryer for cleaning. Enjoy the security of knowing you're fully protected. As with all our car covers, yours will be custom made to fit your car like a glove. This has become my favorite cover.
