I found the rain-X OK on the windshield until it started to wear off. The streaking was so bad I could hardly see at night. It was either reapply the stuff or let it wear off completely. I chose to let it wear off.
I'll never put the stuff on a windshield again but side or rear windows or mirrors are OK.
Same here. I will never apply it to my windshield again. -- "So, Lone Starr, now you see that evil will always triumph because good is dumb."
