Didnt work for me.

No I didn't. I was just kind of screwing around so after I saw it worked I finished that one window and packed it in. Haha. I was being lazy that day. If I protect it with anything though I'll usually just hit it with a spray wax like OCW. Since I use it after every wash I end up with decent protection on my windows.

Thanks, I did my windshield and never topped it with anything. Someone told me to use nxt 2.0

I'm really not a big fan of using a paste wax on the windshield. I've always gotten wiper chatter however maybe the problem isn't so much paste wax as it is maybe carnauba wax. Then again, OCW contains carnauba so I guess that doesn't fit. Just thinking outloud here as I go so take it for what it's worth.

EDIT - I just remembered Nxt comes in both piquid and paste.

Don't use a wax of any kind on the windshield. If anything, use Rain-X.

I agree with the 00 steel wool. here is a link to the steel wool. 00 steel wool

That will soften the water in line so you don't run into this issue again.

ON GLASS. :)

Waxing the windshield, in my honest opinion, isn't a big deal. Honestly, it's fine -- until you run the wipers. Some products may cause streaking at this point in time... but, I only think that will last for a few swipes because the wipers will abrade (friction) the wax layer off in a jiffy.
