for those who use RainX

[siume99]

I'm an avid supporter of RainX, except when it wears off and leaves water smear marks. ??? I've been noticing one problem with using it though......runoff residue on to side windows.  I have streaks of RainX about eye level at the front of the driver's and passenger's side windows.  They don't go very far maybe 5inches in a gradual arc to the top of the window.  Has anyone else experienced this?  Does anyone have a solution to this?

I've been using RainX for years and never had a problem like that.  What kind are you using?  The wipe on pads may be the culprit, I use the bottle where you wipe it on and buff it off w/a cloth towel.  I usually do a few coats on the windshield.  I've never had any problems w/ water spots and just so long as you don't use a very harsh soap when you wash your truck the 30 mins you spent applying it should last you the year.

Whatever you do, don't go lazy and get the 20/10 wiper fluid stuff (green fluid).  I tried it figuring, rainx in the wiper fluid it's gotta be good.  Well I used it and it leaves a really heavy coat of something on your windshield that distorts your vision massively.  Granted I tried this in the rental cavalier so it was even worse cuz the oncoming headlights were at windshield level.  I think it's because it was freezing on the windshield and was almost like a sheet of ice.  But, don't use it, it's not very safe.

 

Right now I use the red stuff or the classic blue, which makes a nice purple.

I don't use the spray on type, because I heard that RainX is the devil on paint and clear coats.  I just use it from a bottle, two coats.  It lasts 3 months or so.  When I said,

except when it wears off and leaves water smear marks

, that happens about the 3 month time frame when I use my wipers.  Any other time, the wipers don't smear.  It's an annoying reminder.    This streaking on the side windows I just noticed a week ago.  (As I typed this I thought of something).  The plow trucks have been getting panicky and have spread salt on the roads.  (I think in a few years, we could start mining salt on the sides of our roads!   )  Perhaps it is salty road spray?  ??? I'll have to see how easily it comes off.

The windshield wiper fluid I use is blue (don't remember the name).  It is suppose to be -20F stuff or something.

Well, my suggestion would be to apply about 3-4 coats.  I usually spend about a 1/2 hour to an hour when I do mine.  That way it's garunteed to last a year.

 

As for the streaks, I'm guessing the salt is your culprit.  I've never noticed a problem before and since you hadn't either, I'm guessing it was the salt combined w/ water spray.  The only reason it's leaving streaks on your side windows is because there's not rain-x protection on them.  The salt water is drying and thus leaving it's mark.
