My new custom fit car cover arrived (after a month)!
It’s a beauty. Water just rolls off.
Here is the official description:
Details: Stormproof represents the state-of-the art in vehicle cover fabrics. After years of research and testing, Coverking found a leading textile mill in Japan which was capable of producing the ultra-micro fiber cloth, but woven in a very unconventional method to produce extreme water resistance, sun resistance, snow/ice resistance while maintaining very high levels of breathability, WITHOUT TREATMENT OR COATINGS! Other fabrics available on the market are the result of marketing hype, with no real engineering - the materials are initially very water resistant, but little breathability. Those fabrics rely on coatings around the fibers which provide the water resistance. Unfortunately, consumers who have spent a great deal of money on these covers soon find that after a year of use, the cover degrades, the water resistant properties have vanished, and the color has faded. Stormproof has undergone a battery of testing to assure it's superior properties remain intact for several years of outdoor use. There is no better material available on the market today.
