the rear window?

cheers

They're OK - but I found they didn't last that long (and they're bloody expensive). I'd use Rain X which does the job just as well (when properly applied) and it can be used on all bits of glass on your car, not just the windscreen.

Can you buy Rain X in Halfords? I had a job getting my car in the garage this afternoon in the rain, so i'd best get some pronto.

Yep to Rain-x in Halfrauds

Its cheaper at Wilkinsons

I'm sure someone will explain but Rain-X made my windscreen wipers judder & squeak like a bugger. Absolute hell to get off. I did follow the instructions to the letter but...Never again.

Never had that Andrew (although I must say, I do replace my windscreen wipers quite regularily - maybe they were a bit old?). I also use the Rain X screen wash additive which helps to maintain the coating and stops grease building up on your windscreen.

I know what Andrew is getting at.

The solution is to add more rainex and use the screenwash additive.

Chris, I think it depends on the car and the mechanism, as much as anything else. Brilliant on sides and mirrors, would not use it on the front screen again though.

Rain-X, over time, just makes the blades shudder across the screen.

Wouldn't use it again, personally.

been using the PIAA wipers for about 4 months now and they have good & bad patches.

They're a bit crap when your screen gets dirty as the washers tend to wash off the silicone coating - and when using them in the day you get a kind of misting effect for a second or so after the wiper has passed.

They are, however, absolutley superb at night when doing a decent speed - the water beads off up the windscreen quickly and when doing about 60-70ish on the A66 at the weekend I didnt need the wipers at all until I got a streetlit area, and it was putting a fair bit of water down.

Seems strange spending twice as much as normal wipers when you're going to use them half as much.

How long does the Rain-X last in between applications?

Which means it is time to cut back and re-apply.

I washed my car once you know, never again, it just got dirty

How long does your car stay clean once you have washed it?? In short it depends on the conditions but I reckon on at least a month between applications and even 2-3 during the summer.

How should Rain X be appiled then? I put it on my back window and it seemed to make little difference if any.

It's all on the bottle ES - but it does help if you have a nice clean windscreen to start with. If you look at the instructions that come with the PIAA wipers - you'll see why this is important. I can safely say it is has never taken me so long to fit a set of wipers!

D might be right about different mechanism, but I've been using Rain X for years on a number of cars and I've always found the results very good. They really come into their own on the motorway - just as messiah mentioned (for the PIAA wipers - but the end result is the same).

The only real downside is a tendancy to smear in very light drizzle. New wipers and the screen additive help to reduce this.
