Mine DOES repel the water, but some still gets through. It does bead the water quite well also, but for some reason the beads dont like to roll off the roof and hood, just sit there. This is where most of the water comes through is on those two spots. Mostly happens in winter, get a coupla inches of snow on it, lower stuff melts and seeps through the cover. But if we get a really nasty rain storm and the cover gets super wet, it will soak through. Not horribly, but enough to make me wash the car. I think it is a Budge car cover, but ill have to go look, its in my trunk right now.
