clay barring just does the same thing to the window as it does to the paint. makes it really smooth! car detailers trick. or maybe just mine lol.

but buffing with corn flour? is that a joke? lold

I have the bosch aero twins. Similar to the ebay ones but brand name, were around $20 each. Expensive yes, but Awesome! mine were squeaky and shuddering all of the time, now you can use them dry and they are still silent. Look awesome too...as far as wipers blades go!

To get Bosch Aerotwins: look up MTQ Engine Systems in your state - you can buy them there for $15.50 plus GST. Very useful.

A few members of my family bought Repco branded ones and they love them!.They perform very well and no noise.

I plan to get a pair very soon.
