PIAA wiper blades worked for me
I installed PIAA silicone wiper blades over 2 years ago.
And they are JUST barely starting to streak.
They came with a premoistened pad of glass treatment that is very similar to RainX ...
I have not used RainX on my windshield in the 3+ years I've had the truck, and I still get some beading.
I will be ordering a new pair soon.
BTW, how DO you pop off the wiper arms? I have never tried to do that before. One of mine has a bit of rust and I want to take care of it...
Thanks!
SilBlade have a 5yr guarantee
They work extremly well here in 100 degree Texas as well sub zero South Dakota.

However, I have switched to the Bosch Icon and Valero recently due to what I consider a better design and am happy with them but have only been using them for about 6 months.
