I'm a Protect-A-Towed user. I like it because it goes on and removes quickly and rolls up to store in a small bad when not in use.
I had a bra BUT, before you put it on your vehicle, you should make sure there's no dirt on it that would get embeded in the bra and scratch the finish on your towed. As you go down the road, if there's any movement at all {like flapping in the breeze) that movement could be just like rubbing sandpaper on your towed. Besides that, they take several minutes to stretch on over and secure on your towed plus storage is a pain - if it's wet, you've got more problems. No more bras for me, thanks.
