I used this product to remove a group of several scratches approx. 3 inches long that were caused by 80 grit sandpaper. The scratches are no longer visible. There is some minor distortion, however, I kept my working area small and did not try to feather the results, because the scratches had been very near the frame. Great product!

When I received the product I used 1500 & 3000 grit wet dry sandpaper first as the scratch was deep enough to catch my fingernail. Then I just followed the instructions that came with the product and the lexan shined up clear and good as new. I would recommend this product to anyone and will definitely use it again. Chris

My windshield on my Varga was really bad with scratches and overspray. Sanded it down with 1000 grit and heavily hazed the entire window. I was concerned but after the use of the kit per the instructions it came out incredible. No need for new glass. I recommend this product highly.

Just like the previous review, its a little unnerving to take sandpaper to your windshield. However, I had a scratch that I could catch my fingernail in. Followed their directions, sanded perpendicular till smooth. Then star using the compounds and polishes and youll be an expert. Nice to have all the tools, compounds and polishes in one kit.

Superb product that really delivers the goods. Takes a lot of guts to use at first and then you suddenly become a pro at the second window. The final result is simply like new. Medium scratches gone. I was very surprised. Highly recommended. Instructions are clear and to the point. 10 out of 10.

Aircraft Spruce assumes no responsibility or liability for any issue or problem which may arise from any repair, modification or other work done from this knowledge base. Any product eligibility information provided here is based on general application guides and we recommend always referring to your specific aircraft parts manual, the parts manufacturer or consulting with a qualified mechanic.

Q: Do you wet the application pad?

This kit will have the manufacturers application instructions. Review the application instructions before use, but they do mention to wet the abrasive paper, but did not mention wetting the application pad.

Q: Will this product remove the white haze on aircraft windows?

It could. It will remove light scratches and polish out surface haze. It would depend on how bad the hazing is on the window. If the haze is from crazing then it cannot be polished out.

Q: Will this remove the fogging in the windshield?

It could be used for that. We would not be able to guarantee that it would work though since the severity can vary.

Q: How do you know if the hazing is surface or crazing?

If the windshield feels rough to the touch it would likely be a surface issue. If it is still smooth it is likely crazing.

Q: Do I need a polisher or drill? if so what size

A standard 3/8" or 1/2" drill will do the trick.

Q: Will this work on a corvette c5 acrylic roof panel?

We sell this for aviation use. It may work fine in an automotive environment but we cannot say for sure. We always recommend using any new fluid on a small test area to be sure it will not negatively impact the finish before treating an entire surface.
