I have tried Rain-X here in Orygun several times over the years........And each time I have "degreased" my windshield before applying.
When it sprinkles, it is'nt too bad, but when it desides to RAIN, and I must turn on the wipers it's like I have OIL on the windshield. One night I had to pull over fast and try to wipe off the Rain-X , using a Tobacco bag, saved the nite.....I couldn't see nothin but a big smear.
I keep the Rain-x in the bathroom, it seems to keep the mirror from fogging up from the shower, but ya gotta put it on weekly...... "BH"
