Now there's a new way to reduce rain fade and loss of picture due to snow build-up - spray Dome Magic directly on your dish and LNB. Wet heavy snow can stick to your dish and LNB, making your digital picture freeze, pixel or go out altogether. Likewise, excessive water on your dish can cause reception problems. Applying Dome Magic eliminates snow sticking to your dish and causes water to roll off in balls rather than spreading in wide sheets. Simple to apply, just spray on. One application lasts about a year. Each 5 oz. can provides 4-7 applications, depending on use. A thicker coat is recommended in wet snow climates. Won't change the appearance of your dish and does not harm the plastic LNB lens. UPS Ground shipping only.
