Anyone found a source for wiper blade refills? I've read reviews, including CU, that claim that they are all the same and replace them every 6 months BUT on every new car we've bought the wipers last 3 years or more and thats on everything from Chevys to german cars to two generations of Subarus. Our Forester's are in the neighborhood of 4 years old and only one is streaking. Our experience is that the oems have always been better for whatever reason. Our blades appear in good shape. So with that, anyone found replacement inserts (not the whole blade) for the original blades? Unfortunately the on-line Subaru specific parts sites list them as discontinued. No point in adding to the mess at the dump if not necessary.
