Swirl marks after 3M Headlight Restore Kit

Start off by saying this was my first attempt at this and a novice for sure. Long story short... tried to restore my passanger side headlight with the 3M 39045 Headlight Restore Kit. Everything went to plan and followed the sanding and polishing steps verbatim. Was successful at removing all the oxidation and slight yellowing that had occurred over 7 years....

BUT after finishing last compounding polish step and wiping it clean, I am now left with a million tiny fine swirl marks. The headlight surface is buttery smooth so I dont feel the scratches. I am guessing I either did not sand with the 800 or 3000 long enough or the pads got clogged and the residue marked the headlight.

Basically my question is... This is fixable right? and if so, what are my options and/or how should I go about getting this headlight looking brand new and get rid of these swirls. Wanted to do this myself, but thinking now I should just take it to someone that knows what they are doing

That should be totally fixable man. I polished my headlights a few months ago and I had similar results, until I hit with more compound and polish. Are you using a power buffer? It saves so much time. Also, you need to hit it with a finer grade sand paper (2000-3000) before the final polish

seems totally fixable. I would hit it with 2000, then 3000 then really polish it out. If done correctly, by the time you get to 3000, you should almost be able to buff it out with your hand.

So does that kit have some sort of UV protectant to add as the final step? I did my headlights about 2 years ago and the sealant apparently didn't have a UV coatings, so they look worse now than before.

Yeh comes with a sealant with UV protectant as final step.

The kit comes with pads that you use with a cordless drill

You might need to saND them down these kits are mainly for yellowing, haze headlights, depending on how deep the rock chips are I recommend ha bing a professional take care of them, they sand them down up to 400 grit making they're way up to 3000 and then polishing them, then spraying them with a clear coat

Hey guys thanks for your feedback on this subject. Me too, I did this job about 2 years ago using the the same 3M product and apparently need to do it again. I remember it came out great but the haze and yellowish came back now. Has someone used over 3000 grit sandpaper or should stick using 3000 until all yellow and marks go away?

How long did u guys use 3000 for, 15m ,30min?

Cheers
