Headlight film

My '05 E46 headlights looked like, like really bad. So I sanded them with
600-1000-1500 and then polished them with a $10 kit I got from Harbor Freight. Wow, really good for $10 and a 1/2 hour. Still, not really great.
Now I just happen to have some urethane protection flim lying around that I would like to try for UV protection. Does anyone have any ideas as to a finer polish/grit that I could use before the film? Or will the film's adhesive just fill in the less-than-perfect-surface? This is just an experiment and for $70 for
new covers I don't want to spend a ton of time on this, but a bit of experience/sage wisdom with finer polishes is greatly appreciated.

Do the kit one more time and stop by walmart and pick up some 2000 grit sandpaper and 3000 grit trizact pads, also m105 and m205 (great car polishes which you can use later on your car)

It should look new if you do this.

In order to restore the lens back to its OEM standards a new ultra violet (UV) resistant coating must be re-applied. Use Optimum Opti-Coat™, which will provide ultra violet (UV) protection, the ultra violet (UV) absorbers are very durable and exhibit a 5 year half life, meaning that every five years the concentration is reduced by 50% percent, a 2-4 µ (microns) film and a hardness of 9H (Pencil Hardness) when fully cross-linked and provides a semi-permanent coating.

I hope the information in this article is of some help to you. If you have any further questions please let me know

Thank you for your suggestions. The Opticote is interesting, however I am curious to try the film ( which I already have ).

The finer grit polish is intreguing as I am not familiar with m105 and m205.
I'll have to go take a look!

Thanks

What were your results?

Generally, taking one step further in sanding would be all that is needed before applying the film. How much time/effort you want to invest depends, really, on how much you want to learn

The films work fine for UV protection. To extend the life of the films, apply a poly or natural wax-only product (no cleaner combinations) every couple of months (or when it stops beading). I've found that this also has the benefit of keeping to keep the lenses a bit cleaner.

I would suggest a light smoke. The dark some will be as dark as VHT.
