This product is absolutely amazing for any winshield that is old and really pitted. I notice a big difference when using this on my winshield that has about 200,000km on it (and looks like it has been sandblasted). This stuff coats your glass with a super thin film of water repelling teflon/wax which reduces surface tension and forces the water to bead up and run off quicker increasing visibility!

Been using this for years. Works wonders. Just follow the instructions, and you will be glad you spent the couple-few dollars on it.

This is an incredible product; wouldn't do without it in a wet climate.  You can literally forget about using your wipers in light rain and mist conditions.

 

I'd disagree on reapplication time; I find I can go several weeks on a single treatment (as many as 8 or 9), though I will admit that the efficacy decreases over time. The instructions are clear and straightforward, and application only takes a few minutes for all windows. Apply with cloth in circular motion, let it set, then polish with papertowel (and a light mist only if necessary).

 

It's worth further noting that some bathroom-installation specialists recommend the product for all-glass shower and tub enclosures.  I've been using it for 3 years there as well, and must say that an occasional application (every 3 or 4 months) greatly reduces time spent cleaning.
