RainX

[Red V8]

Tried this at the weekend... prepped with screen cleaner first then applied RainX as instructed... light rain on way home tonight, and quite frankly I'm a bit disapointed with the results.

Any similar experiences out there, or does it only work in heavy rain?

It depends on how fast you're going. I find I need to be travelling more than 50mph before I can turn the wipers off.

Ooo that was my 5000th post!!!!!

[petros]

Tried it and ,likewise, waste of time.

used to use rain wizard on one of my old cars.. worked perfectly..

And the good lady liked the look of the bottle

Great product above 50mph. Useless slower but what do you expect.... It needs the wind speed to blow the droplets away.

I think it works better on some cars than others - maybe to do with aerodynamics. It worked superbly on my Calibra, but it's not been as good on any car since.

Not tried this stuff on the Chim, but I was happy with the results on other cars.

Works really well on mine. The heavier the rain and the faster you go the better.

[Nuggs]

Yup, love the stuff - it's always worked well for me.

Here's what I do:

1. Clean windscreen;
2. Apply plenty of Rain-x using a dry cloth;
3. Leave for a few minutes to 'fog';
4. Apply another coat of Rain-x;
5. Leave for a few minutes more;
6. Use a plant spray to spray water on the windscreen;
7. Rub with a slightly damp cloth; and
8. Polish with kitchen roll.

Nuggs has got this right. Fail to do it properly and you will be less than impressed. Do it properly and it does the job nicely

I found that it worked great on my old corrado, at pretty much any speed. It worked well enough to not need to use the windscreen wipers anymore....which is just as well as they were crap due to a cock-up at the design stage.
anyway, same stuff on the Chim and not nearly the same result. I'm thinking it must be the actual velocity of air past the windscreen. I find with plenty on it's ok but then there's just more to remove and deposit somewhere elsewhere on the car.
I'm going to apply as suggested earlier and see what happens.
all the best

It makes a different how fast you are going.

It also makes a difference how well you have prepared the screen and thus how clean it is before you start. Also to get it working well you need to be putting on about 5 coats leaving each one to dry for about 5 minutes.

If you do that it should work well. On my Tuscan I found that at motorway speeds I got better visibility without using wipers at all!

buy it whilst on holiday in the US - £2 a bottle there !!!!

I have always used RainX on my race car & road cars, I think it is the best stuff ever. It does need to be raining quite heavy for it to really work, also if you have to use your wipers a lot, such as when it is light rain, it does remove the rainx much quicker

I've used the Wynn's equivalent (found it in a cupboard in my garage - must have bought it > 5 years ago!). Applied exactly same as Nuggs. Light rain starts to bead/run at 40mph - once over 50, no more wipers.

Extra bonus though - assume this stuff essentially fills in all the pits on the screen to make smooth - my ultra crap typical Chim wipers that almost stop unless the screen is really wet now work fine even on a mildly damp screen due to less friction.

So a definite from me.

[Red V8]

Okay, if I read this right, I need to apply more than one coat (contrary to manufacturers instructions) , wait for it to rain really heavy and drive really fast!

Not to be put off, I'll give it another go as per Nuggs advice.

Always worked very well for me. Put on a liberal layer and wait 5-10mins for it to dry thoroughly (maybe it is this step which makes the difference). Then polish off. Apply it about 3 times a year which seems to be plenty.

I have found to work well on all my cars. Its great on the Chimara.

Key thing is to prepare the windscreen with a proper "glass cutter" first to get every last bit of crap off and then to apply two layers of RainX and polish it up really well.

After that the windcreen stays clean for ages and the water just runs off it.

The best use, though, I have found to be on the side windows. Keeps them really clear...

works well on the chim for me. I practiced first on the shopping car & it works fine on that one too.
