[s-cars] Need a good wipe

[Ian Duff]

I've found wiper pressure against the windshield to be a friction  
problem, not a spring strength problem. WD-40 always seems to reduce  
these problems and improve the situation for me.

I've come to think of chattering coming from two causes.
1) A dirty windshield, and not just grime, I mean the residue from the  
blade wiping back and forth. A good, really good cleaning with Windex,  
and not the generic blue water, usually solves it if that's the problem.
2) The rubber takes a set from having been at rest at an angle. If the  
rubber isn't straight down relative to the metal holding it when you  
lift the blade off the windshield, your rubber blade could prolly  
stand to be replaced.
I try solving the first issue first because I'm cheap, and if it  
doesn't work, stop by my FLAPS and get two new blades. I get good  
Bosch blades because not only am I cheap, I'm lazy too, and have found  
them to last pretty well.
