Anyone else getting a lot of fog like buildup of "film" on the inside of your windshield?
I was told years ago that this is the "curing" of all the plastic/vinyl of the new car parts that causes this......just don't remember getting this so much on the new ALTIMA I had.....I clean it and a couple weeks later the film is back...anyone else getting this as much??

Does anyone have a solution to water spots on the outside?

There are a couple of ways to go with water spots. Several people swear by "Bon Ami" which is a polishing cleaner available at most supermarkets. Given that it is not specifically designed for automotive glass...or glass in general, I have not tried it. If you do try it, I'd try it on a piece of glass that you do not care if it gets scratched.

The other product, which I have used, is by Autoglym car glass polish. You may have to order it online, depending on where you live. I live in a small town in Georgia and had to order it from a detail company in Florida. Cost is about $8. The product works excellent! After doing the windows on my new car, I did the windows on my wife's 2002 Windstar that had bad waterspots on all windows. The autoglym product took them right out. Regardless of the product you use, you will need to use some elbow grease to get these hard water stains out.

There is also a product called Spot-X that some have found in HomeDepot and/or Lowe's. The product is expensive $28 and is nothing more than a powder of finely crushed up walnut shells that you mix with water to form a paste.

Just remember that there are a lot of things harder than automotive glass, which has Moh's hardness rating of 5.5. A higher rating will produce scratches in a lower rating. Scouring cleaners (comet, ajax, etc.) have a hardness rating of 7.5. Green Scotchbrite pads have a hardness rating of 8. Lots of people have had to have windshields replaced because they have used these pads only to find they have instilled hundred of scratches in their windshields that impairs visibility. Steel Wool is 8.5. I think that 00 and 000 steel wool ratings are lower, though.
