well I don't have any experience with the Ultratect cover. I don't know if there truly is a perfect car cover. I've had to make modifications to several over the years to suit my needs. Plus, to get true weatherproofing (is there really such a thing) you would need different materials (heavier weight and thicker) but then you end up giving up some feature for another. Ding protection, UV, Light weight, storage size etc.
as far as drying...i think the manufacture recommend you leave it in place? Not many people have the space to remove a car cover and let it air dry.
I have the Cover craft Weathershield HP and have been very happy with it. Its light weight, rolls up small and comes in a wide variety of colors. But it does lack ding protection and I wish the UV was higher as thats the killer her in Hawaii.
I suppose I have given up hope that a single car cover can do it all.
I hear you brother....
