Wondering if anyone anyone has used longer than stock window wiper blades. One part store told me 17 in. on both sides, and another told me 18 in. on both sides. I got the 18's and measured where they wipe and found there is over an inch of clearance, room to stick 19 in. blades. Does anyone know if it is not a wise idea to run longer blades. Do I want to be able to push off snow or? Wantin as much coverage as possible due to our rain here in Paradise, CA. We average 75 inches of rain/year up here at 2500 ft. When it rains, it POURS!!!! For a couple day storm we can get 3 inches of rain!! then it's sunny for a couple of days...I love our four season weather here in Paradise. We also have snow in the moutains for the winter. Just have to head up another 1000 ft, which is about 20 miles to snow wheelin.
