What's in that? Does it actually work?

I've got an old minivan whose lenses are more translucent than transparent.

There are a *ton* of variations on this theme but I'll link the MSDS for 3M headlight restoration kit.

http://headlightrestoration.org/files/msds-3m-39008.pdf

WATER
SILICA
HYDROTREATED LIGHT PETROLEUM DISTILLATES
KAOLINITE
OLEIC ACID
ASSOCIATED MINERALS Mixture
SOLVENT-REFINED HEAVY PARAFFINIC PETROLEUM DISTILLATES
QUARTZ SILICA
GLYCERIN
MINERAL OIL
POLY(OXYETHYLENE)SORBITAN MONOSTEARATE

So this one is basically a polish compound (mild abrasive) with some petroleum distillates and paraffin (wax) components.

There are some of these things making extraordinary claims of 'nanotechnology' I suspect this means that after you buff the lense with this very mild abrasive they provide a compatible clear coat. You might want the clear coat. Some of them claim to restore that clear coat that already exists...problem is we don't know if the camera lens has such a coating now...or if it's the same or compatible composition. On a car with a lot of wear...I bet the coating is already damaged so I've never forked over money for that sort of thing.

I've had decent luck in the past with the Mother's buffing product (on cars!):

This is like detailing...go slow and be careful...also keep in mind that no amount of work will clear the damage to any metalized parts that might have melted within a vehicle headlight...but with that Caswell may have a brush plating that might help you.

All of this...of course...is over kill for this tiny lens.

The camera lens is likely to have several coatings as most camera lens do. One may help keep internal reflections from affecting the visible video, one helps protect the lens from abrasion, one helps with IR and one helps sun or bright light flares.

Image processing is hard enough with good images. I personally wouldn't spend time trying to fix the lens. If this is on a 206, simply screw it off and replace it.
