Pros: Despite this product, Rain-X is a good brand...
Cons: Did not appear to do anything.
Ive always been annoyed by that fog that forms on your windshield when it first starts to rain. Sure, you turn on the air-conditioning, turn up the heat and the fog is gone in seconds. But then you have a warm car. If you have the air conditioning on cold then you are still fogging up the windows. So I bought this product (Rain-X Anti-fog) and hoped for the best. Unfortunately, it didnt work. Maybe it works in that fog forms later or is less severe. I dont know. All I know is that I still get fog on my windshield and it seems to be about the same as before.
The product is generally sold in a liquid form (7 ounces) for $4.99. The application of the product is similar to Rain-X, in that you apply it with a rag and then remove it with a clean rag. Unlike Rain-X, however, which goes on the easy-to-reach outside of the windshield, this goes on the inside of the windshield and on a 2000 New Beetle that means it is very hard to apply. For me I put total application time around 5 minutes, and since the inside of my car is warmer then the outside, it will bring a sweat.
After application, I drove around a bit. Without the product I seem to get random fog on my windshield during rains. With the product I seem to get random fog on my windshield during rains. I didnt notice a pooling effect of the previous reviewer. In my case I didnt notice any major effect at all. Perhaps there is less random fog maybe with a 50% reduction in fog I would not notice a major difference. After all, fog is the type of thing you only notice when it was there. As for durability of the product I cant tell. My best guess is that it only lasts one day.
Like the other reviewer, I also had a little problem with this product leaving streaks on my windshield. In my case it wasnt all that noticeable (more like having a dirty windshield then something you couldnt see out of) but it was definitely there. The streaks came off with my usual application of Windex.
Also I didnt notice any problems with this product on the interior plastic of my car. As I mentioned earlier, it is a bit difficult to apply to the windshield of a New Beetle and there is inevitable Spillage. I did not notice any problem with the spillage which I simply wiped up with a rag.
The regular Rain-X is one of the better products in existence. This one it just doesnt seem to work. I figure it must work a little, otherwise they couldnt sell it, as it would hurt the brand. Or maybe the product works for other people. But for me it didnt work, and it made my windshield a little bit smudgy. Since it doesnt work, I have to give it one star. I definitely dont recommend this product to anybody.
