Has anybody found an alternate to Winnebago blades. I have a 27N and they want $40 each. Mine are only 18 months old and the RV is always covered. Winn P/N # 189546-09-000
If yours are only 18 mos old and the rubber is not ripped I would try cleaning the rubber with 400 grit sand paper then wiping them with silicone spray. It just removes the outer layer of dry rubber that causes the streaks.
