Just got a 08 IS250 1 week ago, and when it rains even a light rain i cant see out of the front windshield. Even with the wipers on full blast it is very hard to see. You guys got this problem?

 

clean the inside of the windshield

 

The water doesnt seem to bead off, it just stays there. I dont think I should have to use rainX for a 1 week old new car. The dealership said that I have to let the windshield "breakin" before it will bead?

 

You shouldn't use rainX at all.

 

the windshield is already coated.....

 

Ill give it a few weeks before I take it in.

 

The issue is that the car is covered in a material called cosmoline to resist corrosion when its on the boat. This is removed at the port. You've got residue on the glass.

Go to the store and by some detailers clay and some quick detailer to use as lube. Clay the windshield, once you do that you'll have no problem.

 

I use RainX and it works great!

 

I will just say that Rain-X no longer lists their ingredients for a reason. I never use their products anymore.

 

seems like you just answered your own question hahah. anyhow... i spilled some rainx on the fender of my old car and it stained the paint!

 

I cheated and looked at another forum. I needed a quick answer it was really bothering me. kind if like how you get when you have less than quarter tank of gas left.

 

i used rain x works fine, dripped on paint but imediately washed it off. so far so good. but the stuff really works/helps. but a lil sketchy now since a couple of you say dont use it.

 

Been using Rain-x for some time too...been pretty happy with it...

Are you saying it is not safe for the paint? Can you post some proof of this? I would stop using it if there's some evidence that it will harm the paint.

 

Alright, I'll get specific: Rain-X uses sulfuric acid to 'etch' your glass so that the hydrophobic liquid can bond. These etches show up as micro scratches and pores which is what blinds you in the morning and evening when the sun is at the wrong position.

 

No, if possible, it is worse for your paint than your glass.
