Headlight Polish To Remove Scratches?

[TORX]

The 40 I recently purchased needs a lot of work. I know that cerium oxide works for scratches, but as always there is nothing like that locally that I have found so far. Has anyone heard of or used headlight polish kits instead? Most of the scratches are barely even catching a fingernail swipe, but there are a lot and I would like to fix it before I get water in it.

I believe most headlight polishing kits are just made for removing oxidation and damage to uv coating on plastic headlights. The only ones Ive seen contain 600,1500 And 3000 grit sandpaper for standing the damaged finish off then require the polish only be applied at the end a simply wiped clean and then needs to be reapplied at routine intervals. Don't believe they would pan out to well with glass.

That is what I thought as well. They would also be designed for plastic not glass.

Amazon.ca here I come again...

Windshield apoxy or possibly even just clear apoxy might work? Typically it's used to remove "bullet holes" or small hair line cracks but I don't see why it wouldn't work with a scratch. Fill the scratched area with the apoxy, let it cure and then scrape off the access with a razor blade. Might be worth a shot?

I've got a jar of cerium oxide.
Bought it awhile ago to fix a tank. Stuff is really expensive.

Pm me if you wanted to buy some.

Windscreen polishing kit arrived today. It comes with buffing disks and 1.2 micron cerium oxide. Grabbed up some 3.5 micron to get the party started.

Also some 3d printer parts came in.

So Torx did the Cerium oxide work to get rid of scratches? Did you have to apply it and then buff it out? I've got a nice aquarium in my garage and it has a lot of fine scratches and no big gauges so I was thinking about trying to buff them out. How good of a job did it do?

The cerium oxide worked great. I also grabbed up a glass polish kit off Amazon to go with it. I used the cerium oxide powder and the pads from the kit. I spent about an hour doing tank. It works. I got out the bad stuff. There are still lots of scratches. That has nothing to do with the product or the method. I just did not have the time to put into it then. I still have a ton of cerium oxide, it goes a long way. I suggest an angle drill if you have one, or some other buffing wheel. I recently used it to clean my headlights as they were completely fogged over. Like probably shouldn't have been driving at night fogged over. Now they are crystal clear and almost look new again despite them being 16 years old. I told my self to get before and after pictures, but I started with out the before and remembered half way through finishing the second fml.

Thanks for the insight. I will find the time to do tank in garage. Do you think 100grams is enough to do front glass on 120 gallon tank?

Oh for sure. It goes a long way if you don't rinse it away constantly.
