I had trouble with the Piaa blades in the winter, they iced up on me even with using an anti-freeze windshield washer fluid. I love them during the rest of the year but I'm not sure if I'll use them again this winter.
I got a set of Bosch micro-edge excel for my car and a pair of cheapos (entire blade) for my gfs' car . The micro-edges are really nice....really 'powerful'. I think I got used to my old and rotting blades of 3 yrs, hehe. Haven't seen what cheapo blades can do yet, though.
Is there anything in the auto shops I can use for washer fluid? Every dern thing I see has methyl alcohol in it . Man, you're a true Autopian when you buy washer fluid online .
