Guys, thanks for the sympathy. No Rain-x, not even washing the windscreen with wash & wax shampoos. Tried all the BMW products given to me. PML polished the windscreen to remove any residue and even changed the wipre blades. One of the bro recommended Newpaper (weather page) and scrub like hell - done that and its still noisy. The funny thing is that after every wash, clean and scrub, if you run your fingers along the windscreen, you can feel the resistance. Its only on the wiper area of operation. The area outside the reach of the wiper is sliky smooth. Just want to vent some steam cause I was really pissed this morning. Spoken to PML and they promised to get back to me for answer. Change windscreen next maybe????
Janson - thanks for the advise. Maybe you should send me a photo so that I can paste it in front of the windscreen. That would remind me of a poor soul who is suffeering more than me. But sent a decent one, don't want to fighten the kids. Thanks for cheering me up.
