Seems still work well at removing a thin layer of plexiglas to remove small scratches. I still have some deeper craze lines, but they are not as noticeable. You will need a polisher to use this, and price is about double what it should be for what you get, just like everything aviation!

We had some hazing from a previous cleaning product and after buffing the windows came out almost perfectly clear again. Would definitely use this product again.

Q: My windows have a small amount of hazing. Can I use the aviation window restoration system kit to remove scratching and not use the final protective step?

Per the supplier: I would proceed with step 1 and 2 only and would not use step three as this does not remove hazing or scratching. Steps 1 and 2 will not remove scratches deeper than 4 mils.

Q: Have Cessna 172 with original windows (1976) rear windows have milky look. Will this work to restore them?

This is commonly used to restore aircraft windows. The success of each application depends on the severity of the scratches and haziness of the windows. We cannot guarantee complete success of each job.

Q: I have a bonanza, how many windows will this treat? Will I be able to use it on the interior as well?

It should be enough for to treat all the windows on your aircraft, but that does depend on the severity of the scratching and the users polishing experience. A more skilled user would likely need less product.
It can be used on interior windows but it could get messy and you would need to cover everything.

Q: Can I do the front windscreen in two parts, that is, two halves, or does the entire window need to be done at one time?

You could, but you might want to tape off the finished half when you start on the other half.
