rain x and a pitted windshield

was talking to acquaintence today and mentioned that the windshield on my 20 year old diesel was badly pitted and how i was reluctant to spend $300 or so on a replacement. well, he shared the fact that years ago he applied rain x to a pitted windshield and while it was not the same as new glass there was a noticeable improvement in visual clarity. (?). anyone have favourable experience using rain x to reduce the ravages of pitting? thank you.

I use Rain-X on my vehicles and I like the job that it does especially in mist and light rain, but I've haven't noticed any help with the cracks and pits. Good Luck.

I thought it helped on the tiny pits from sand but that might just because the windshield was really clean after I put the rain-x on.

I have noticed that Rain-X helps some with clarity but not as good as a new windshield. I tend to put Rain-X on all my windows every 3-4 weeks just because it does help bead up rain and snow.

I'm a rain-X fan

And I have a 25 year old windshield. RainX is a great product, but I don't think it helps much with pitting. I tend to agree with Wasuchi, a clean windshield helps more than RainX.

I know I need a new wiper, but I have been wanting to get some Rain X and always forget when I'm in the store. My mini wiper at the base of the arm is gone (I accidentally ripped it when I was scraping last winter) is it possible to find a new one? And also a whole new wiper arm. I'd like to have a fresh spring to apply good pressure on the window for a clean wipe.

I tried all sorts of things to 'fix' my pitted windshield (some aftermarket brandless glass). Finally gave up and put in a new Pilkington Glass...

I can't believe how much nicer it is to drive the car now...
Worth all $250 I spent... the new windshield seal also stopped the leaks!!

I tried Rain-X on my 19 year old 240D and the rain did bead up, but my 240D couldnít go fast enough to get the beads to run off the windshield.

Seriously, it worked fine for a few weeks but where I live there arenít enough dry spells in the winter to re-do the Rain-X every few weeks. I donít have a garage for the car, otherwise I could do it in there. I didnít like the Rain-X effect on the wiperís ability to sweep the moisture off. Seemed to leave a film.

rain-x is GREAT for the rain, especially at night. i don't even use my wipers at night as long as not many car's are coming towards me. you can't even tell there is water on the windshield. unless the headlights of a car point towards you.

as for clarity, Rain-X creates a haze on your windshield that you are supposed to wipe off. putting Rain-X on there and not wiping it off will just make visibility and clarity worse. plus if you ARE putting it on, you're supposet to have a clean windshield anyways.

As mentioned before , a clean windshield to start and buffing it a little with a nice clean cotton rag. I notice at around 45 mph it starts to blow right off the windshield and is very clear, I put it on the goggles for motorcyling , skiing etc. It works great. Hans.
