RainEx

[Zaul]

I've done a search and couldn't find anything, so apologies if this has come up already.

I've used RainEx regularly on my old car but without any knowledge of whether it has any detrimental effects on the wiper blades etc.

Before I start to use it on my new GTI I just wanted to check whether people here had any advice/thoughts.

Thanks!

Go for it, won't effect rubber but keep it away from paint.

lol why would it affect wipers if it's a protectant? They wouldn't be able to sell it if it did

I'd suggest Nanolex anyway, RainEx is very temporary and umm...''average''?

Nanolex hey... Do tell!

I've been using rainX for ages but it annoys me that it disappears after a few months, IF you keep your car regularly clean....

It's been over 10 years since I last used Rainex on a car so it might have changed... but I found it was fantastic for windows that didn't have wipers, but just caused the windscreen to smear the water rather than wipe it off.

Yeah it's really only a temporary thing. I used it on my car over the weekend because I had no alternative immediately after polishing, and it's still a crappy finish and I can see the application marks (probably means I used too much though hehe).

Nanolex on the other hand is actually quite amazing! First time I used/saw it was about three weeks ago. It's called Nanolex glass sealant Premium, or Urban - comes in two styles to suit faster or slower average driving (highway/city). It lasts about 4 months on windscreens and is a very strong and durable coating that will obviously protect the windscreen from wiper and stain marks where rainex really won't...

It's expensive, but so is all Nanolex - mainly because you'll use nearly nothing from the kit you buy. You'll keep the bottle for AGES - might even be worth getting a detailer who stocks nanolex just to apply it on your car for you.

Yeah I found that as well - not a very nice coating because it's cheap and cheerful...

Definitely go the Nanolex! I have been using it a fair bit lately. It actually feels like there is a sealant on the glass, it goes really smooth and water beads off at about 40kmh

Lucky prick...I've only used it like twice haha. I'm gonna get some on my windscreen when I take that damn RainEx off...

A tip about RainX. I found out (about a year ago) if you ever use this on your windscreen you will never be able to get your windscreen repaired if you get a minor chip or star that can normally be repaired. I had a small star on my Golf 5 windscreen and when the repairers came to inject it with the silicon or whatever they use, it just would not take. The guy asked whether I had ever used RainX on the glass. I said yes, and he said I should have been asked that when I booked the car in. The repair just did not work. Fortunately they did not charge me for the repair as it did not last long and wasn't a roadworthy repair. I ended up with a new windscreen as a result which i was able to claim on my insurance premium. This was a good result for me but if you do get a minor chip but you can't repair it easily because of the RainX, a new windscreen is a bit of an overkill.

That sounds like a lazy repairer without proper knowledge to me (simply because Nanolex is a billion times stronger and even that comes off).

RainX comes off, just like any other synthetic sealant style of product...bit of alkaline wash, or isopropanol spray, until the glass surface doesn't bead water, and you will be fine. Failing that, grab a scotchbrite no scratch pad and use that with it, it'll come off easy!!
