Nope, you’re an epic fail. Overspray on the paint is a GIGANTIC NO NO!!! The freakin instructions even say to cover the paint to avoid overspray.

I did mask the surrounding area and still got a bit of spray on.

Not a big deal. You can use some diluted alcohol to clean it off without harming the paint.

That was an oversight on my part and im currently making corrections and will resubmit the video. I'm guessing you were the one that commented on the video as well. I do appreciate you noticing and commenting so i can remedy this mistake immediately! I appreciate it! I'll also give a special thanks to you for mentioning this to me!

After having the coating cure since last week, i was able to remove the overspray with the all mighty handy dandy denature alcohol. Haha.Like you said, not a big deal, no damage to the paint and was easy to remove even after fully curing.

I used this same kit about a year ago, headlights looked good for a couple of months. After ~6 months every little imperfection started showing, now it's looking hazy again. But I did have to drive in shitty winter conditions, all the gravel and road grime being flung at me probably didn't help.

I suspect that to happen. Due to how easy it was to apply, it did say it would work for about a year. Denature alcohol does remove it relatively easily. I'm guessing to help prolong it, you can layer it was some UV protector or possibly use the "severe" kit that uses an actual drill. But overall, the amount of time it took to apply and the price, i can't be happier. lol

I'm kind of wondering about using the acetone vapor method.
Remove the factory protective layer (ultra-fine grit sandpaper?).
Put some acetone in a 12v heated mug with a funnel cap.
Let the vapor smooth out the plastic.
Then put a protective film (like this) over the headlight.

Just make sure the mug liner and funnel are acetone compatible (no ABS, polycarbonate, acrylic, etc https://www.plasticsintl.com/chemical-resistance-chart)

Ohhh, that's very interesting right there, first time i've heard of this method.

Has anyone tried this?

Ehh I don't know how I feel about that. I'll stick to either a drill mounted polishing pad with the compound I mentioned like I have been using now for a considerable amount of time, or the same compound but using a 3" air powered polisher to do the work and probably get significantly better results.

Having acetone near any painted surface? Nope, I don't trust myself doing that. I tend to have butter fingers...

If you take the headlight assemblies off the car, that could work.

I remove front bumper and fenders when I want to do any wet sanding. it really makes life and the job SO much easier since the car body is holding the headlights. Then I can easily go nuts wet sanding and then polishing to get an extremely smooth and clean finish.

Mind you my example was a polish all by hand... The last time I went all out with a good wet sand and polish (followed with sealing and UV protecting), it lasted years without deterioration or fading.
