Rain-X 800002243 Glass Treatment- 7 fl oz.

Q: How often does Rain-X need to be reapplied?

A: I see degradation more quickly than the others, or maybe I set the bar higher because I want it working like new all the time. So basically I have to apply it before every rain, unless it's been less than a week since the last coat. So yes it'll work for months, it just depends on what you consider acceptable.

Fyi; I also noticed the more pitting on the glass the worse it works, so that's a huge factor in effectiveness and time span, and possibly the reason many don't get good results. It took me a while to figure out why it worked much better on some cars, until I replaced my windshield and suddenly it worked better than ever. A little light came on and now you know too ;) Each year after that I could tell the difference thanks to said pitting from sand or whatever is causing it. The sun seems to shorten its life quite a bit too, as does using the wipers over it so I try to only use new wipers and only wipe if I really have to. So I guess the short answer is you just have to try it and find out how it works on your car, but it's certainly worth a try because when everything is good it's awesome stuff. As long as your speed is enough to blow the water off it's by far better than any wipers, and that's more obvious the harder it's raining. It can be raining so hard that others are driving ultra slow because they can't see, but I can see just fine! I use it on my shower door too btw, but like the windshield you need to get it really clean first! For the shower I use scotchbrite and comet. For the car I find that Windex isn't really good enough so I have some window cleaner that's a paste, which you wipe/scrub on with a wet rag to get it super clean, then let it dry and wipe off the white powder. I forget the name and the label fell off long ago, but it came in a white plastic tub of maybe 16oz. It's the ultimate window cleaner if you can find it. They also sell a version of RainX that you add to the wiper water, which isn't as effective but is really nice if you don't feel like manually doing it, or rain catches you off guard etc. Simply squirt some washer fluid on, even while it's raining, and it starts working right away! I've been using the past several months and it's great. see less

Q: Approximately how many applications is this bottle (7 oz.) good for?

A: Of course it depends on size of windshield, but in my experience with a Toyota 4runner and an Infiniti g35x a full bottle of rainx will generally give 15-20 complete windshield applications

Q: Has anybody tried this on a (plastic) motorcycle visor? Does it work?

A: If you can wax plastic rain-x would last longer

Q: How is this stuff applied? with a cloth like a wax?

A: I use something small because as others mentioned it's wasteful otherwise. I think cloth is best but a paper towel seems to work fine. So yeah, kinda like wax: Clean the glass really well, then apply making sure you get it everywhere, let it dry for maybe a minute or so, then buff off. I and the rest of the world used … see more I use something small because as others mentioned it's wasteful otherwise. I think cloth is best but a paper towel seems to work fine.

I and the rest of the world used to have trouble getting a streak free finish when done. Really it was never streak free, you just kept wiping/smearing it around until you gave up. I bought some micro fiber towels and now it's actually streak free and done in a fraction of the time. So fyi... see less

Q: Can Rain-X be used on the inside of my glass shower doors?

A: Just installed a frameless shower in our Master Bath. Installation people said Rain-X would work great. Did it------Seems to be working well------although we still squeegee down the shower to remove excess moisture.But you are Good on using Rain-X in your shower.

Q: Is this gel or a liquid?

A: It's a liquid that is best applied with a rag. Once it dries, use another clean rag to wipe the film off. I found it's best to do at least two applications.

Q: As anyone tried Rain-X to help keep snow accumulation off satellite dishes?

A: Our dish technician suggested Silicone Spray Lubricant to keep your dish clear of snow and ice. Some guys suggest Lithium Spray Grease as a different strategy. Good luck!
