Bra for toad

I bought one for my Chevy Sonic (before I traded it) and used it a couple of times. Kind of a PIA to install, never really fit as I thought it should. Regardless of that, The instructions say to take it off, let it dry if it gets wet. Here in the south it rains a good bit. On long trips you’re bound to get rain, and of course when it rains water from the rear wheels, passing cars, will all end up on the toad. Ended up taking it off for good after a few weeks. Does it help prevent paint dings? I suppose, but I’ll not get another.
