If you buy a quality bra, (one that fits very snugly) and keep the bra DRY and clean - weekly, the benefits are huge...The bra will not cause your paint to fade. Sun heated moisture (usually from lazy owner-idiots) that is trapped in the bra (from not removing at car washes and rain) will actually steam your clear-coat--causing it to become cloudy...Keep the bra dry and buy a good one--Colgan Custom is the best....
