Yes! I had cheap Rain-x ones before I switched to Latitude and your going to soon realize why you didn't do this earlier. Although the only downside, they are a bit pricey. But treat your Lexus right and just get it.I highly recommend Rain-X latitudes.
Quiet, and work like no other!
Last resort cleaning tip.....guess i got the cheap rain x ones ... sucks cause they are fairly new (I am a broke student), guess ill use them for the remainder of the rainy season/deal with it, and change them out next yr.
I had Rain-X in my car for a while... and there was a period after I started using it where my wipers were also very noisy. It was almost embarrassing. But now it's fine (not using Rain-X anymore).thats the thing, the wipers are fairly new. i have heard things about rain x, and that it may be causing this? when the fully extend to the left (drivers side) there is this sound.
