I've been dealing with this problem for months and months, every time i come home from work i would see my car cover blown off of my car and usually down wind under someone else's vehicle. It is very frustrating, especially living in eastern New Mexico where the wind and sand is really bad. I tried tucking it under every crack and crevice on the car, I tried putting Velcro strips that i bought from Walmart on it as well, and it would still blow off. So who would have thought that simple binder clips would solve the problem. Lol its really simple but its cheap and it works. You can pick up a box of clips for a few dollars at Walmart.
