Default Rain X behavior at low speeds...

hey, i hope this isn't redundant or been discussed elsewhere. i did some searching and reading and didn't find quite what i was looking for...

so, dating myself, i used RainX way back when it was pretty new in the early 1990's. my experience then was that it worked really well at highway speeds where i pretty much didn't even need to use my wipers at all.

the downside, however, was when i was traveling at low speeds. not only would the water beads not "sheet away," but i found my wiper blades didn't work very well because perhaps the windshield was so smooth that they couldn't squeegy away the water.

has the formulation changed? what are people's experience with Rain X for around town driving? do their wipers work "normally"?

RainX is horrible. For a product with "rain" in their name you'd figure they'd work much better. I have been rocking Bosch lately and they work much better.

^ I dont think he is referring to wiper blades themselves.

From my understaning and limited research, rainX window solution works, but for only limted amount of time before it wears away. I've heard better reviews of this product http://www.detailersdomain.com/Adams...Kit_p_545.html

We have offered Aquapel for a few years now and feel it is a much better product then RainX. Offering better overall performance.



If you have any questions, please feel free to contact us.

I believe its stated on the bottle that its 40mph and up efficient. I use it all the time, and its very dependent on how clean the windshield is before application and how often you use the window sprayers and what solution you spray as well.
From my experience the best application is to put it on an hour or so before a good rain storm is coming and not wipe the haze that appears when its dry....let the rain clean the haze, weather its driving or sitting over night. I usually clean my windshield with denatured Alcohol once a year to get it 100% clean to the base and then apply the Rain-x...its sticks around the longest after that. I have also found that if your using a de-ice windshield fluid it will burn off the Rain-x pretty fast unless its their brand fluid. Also if you put Ammonia in your windshield fluid the Rain-x is toast.

Old wipers will take the Rain-x off particularly fast too. I replace my blades like 3-4 times a year. A good money saving tip on that is to buy the new good non-metal wiper blades and then when the rubber is shot get the cheap old school blades and swap out the rubber edges. It takes like 10-15 min and will save you like $35

Yup it will bead heavy, untill gravity pulls it down the windshield, or the wipers squeegee it off. Are you sure your blades were in good shape, and not getting worn? The only time my blades dont seem to take the water off at low speed is when there is soo much water on the windshield that it over flows the blade.

rain-x was 'new' in the early '80's...not the early '90's I think it hit the market, originally, in the mid '70's, actually
I still have a bottle from that era in the bottom of my toolbox

and yeah....it works fine if the blades are new-ish and at lower than 40mph

i have used it and loved it and used it and hate it

i dont use it any more...more hated it than loved it

I would be inclined to give the aquapel a shot to see if it works more/better/something than the rain-x

I use it on everything (or a version of it), works great for racecars that may otherwise not have wipers at all, or using wipers would be distracting. Keep your blades fresh and re-treat annually, no problems.

We had a loaner car for a few weeks that did not have any rain treatment, got caught in two pretty substantial downpours, and were nearly incapacitated...had to pull over. Never had to do that with a treated windshield.

haha. i guess it was new to me in the early 90s

i did have new blades put on at the time (can't recall the brand or quality) on my 1973 Ford Country Squire Station Wagon. it was really horrid to use at low speeds with the blades even when new. i was glad when the rain x itself wore off so i could have good blade function at lower speeds. i liked what it did at highway speeds, though.

since then, i've avoided it, but have seen some very positive comments elsewhere here from people. (but it may be one of those "different strokes for different folks.")

never see torrential downpour here in CA, so i may be safe just sticking with the normal wiper blade function...

Keep in mind that the spray is diluted so that it also works as a window cleaner. I does its job, but only for a short period of time. If you want it to work great do as stated above. Clean the windows with alcohol and then apply the more viscous product. If you get the window really clean and really work in the product you will get awesome results.

I've been really impressed with Aquapel, been on a couple months and still working as well as it did the first day.

I have never applied the window treatment, but have used the washer fluid, and occasionally when I'm feeling lazy I'll take my car to the car wash and pay the extra $0.50 for the RainX treatment. I love the way it beads and the wipers take the water away pretty well even in heavy rain/slow speed situations often seen here in the Portland area on the drive to work.

I guess it never really "wears off" because I reapply it every time I use the washer fluid...

I also change my wiper blades about every 9 months. I saw no noticeable difference with the RainX wipers vs the cheapo Wal*Mart special so I use whatever is cheapest...

Just wax your windshield it will last for a very long time, I've been doing it for years and have never had an issue.

I've been using rain-x on my wrx since i got it in late 2005 and it works VERY well. At low speeds my wiper blades work fine. Maybe the OP's blade spring pressure isn't so strong?

I apply rain-x after almost every time i wash my car in the summer and it lasts through the majority of winter becuase of it! i also use rain-x washer fluid so that helps too.

good point: it was a 20 year old car when i applied RainX to it...shouldn't have that type of problem with a 2012

Even really worn Rain-X is better than bare glass. The only time I need to put my wipers on is when another car runs through a huge puddle.

I use rain-x treatment and it works great at all speeds by making the water bead up, at low speeds it just doesn't fly off like (think <35mph). However even at low speeds having the water bead gives you much better vision. I hardly use my wipers because of it and usually can go 2 to 3 years on blades. I apply the treatment 2-3 times a year. I also agree with comments above to thoroughly clean the windshield before treatment.

I second the rain x windshield stuff. I hate the price compared to regular stuff, but I really do not use that much.

i have no problem with rain-x...i spend the extra buck or two and buy their brand washer fluid too and it keeps my windshield steadily beading water with maybe one new application of the concentrate per year

when i think about it though, there definitely is a distinct cutoff, which does seem to be about 40mph where the rain doesn't roll up the windshield on it's own, i never really have an issue because almost all of my driving is 40mph or higher though (except at obvious stop signs etc, but don't do a lot of city driving)

still, my windshield wipers don't experience any ill effects when i do have to use them with rain-x applied and speeds less than 40 mph

I was unimpressed with the spray. It's ineffective as a cleaner as it leaves a haze that needs to be wiped off once it dries, anyway. It's not as effective as the regular solution because the original formula was diluted, like you said.

In the winter RainX helps tremendously to prevent window icing and makes removing it a breeze.

I bought one set of blades when I bought my car 5 years ago, and another set this year. Top line whatevertheyare's for about $60/set, or about $12/yr. Not having to change blades all the time is worth the money. I like working on my car, but not replacing mundane items more often than I have to.

I've also had success with RainX, but the SVX does have a much more sleek windshield than an Impreza.
