    This is an amazing product. I recently purchased a project airplane with a cloudy scratched windshield that I thought would have to be replaced. I decided to try this product before writing off the windshield and was amazed with the results. The windshield now is hardly discernable from a new windshield and will go back on the airplane. This is money and a bit of time very well spent.

    Bought this kit to removed some small scratches and a couple deeper ones in my Piper Arrow. The kit had plenty of product to do all eight panels inside and out, and everything looks amazing! The process is time consuming, but it works perfectly and the windows look brand new. Kit says to use 600 wet grit for deep scratches, which I did initially, but found 800 just as good and doesn’t require as much work to get back to clear. But, overall, an amazing product I would buy again for maintaining clarity and several others at my airfield have already ordered kits after seeing my results. Best $45.00 you’ll spend on your airplane!

    My side windows were looking hazy/foggy, thinking I would need to replace them soon. Decided to try polishing them before buying new windows. They dont look new, still some deeper scratches, but they are clear again and I no longer think I need new windows.

    I thought my windscreen needed to be replaced, and only gave this a try to improve it a bit if possible, as new windscreen was going to be so expensive. This made it like NEW! Very very pleased.

    Tried polishing a new windscreen for my experimental using a polishing cloth kit, all the way to 6000 grit cloth. This only made the situation worse. This kit worked great and the windscreen is now in my airplane.
