Any online stores with great rates on replacement windshield wiper blades? My local superstores always seem to be out of my sizes
No there isn't something that will make them last any longer with out compromising the effectiveness of cleaning. Wiper blades are supposed to be replace at least once a year and maybe 2 times a year. Do yourself a favor and buy the factory refills from the dealer or buy Rain-X wiper blades. I have purchased just about every blade there is from the cheapo store brand to the triple edge. For my money nothing has worked better or lasted longer than the Rain-X blades. They worked so well I started selling them in our parts department. Every once in a while I'll get a customer that has a blade that is jumping or streaking, and it usually turns out to be a bent wiper arm or worn out spring on the wiper arm.
impossible wiper blades can be found most everywhere auto parts are sold easy your not looking i can think of about 200 places i can walk to and get some
