97 Outback - headlamp lenses dulling

[Kevin]

I have recently noticed that my 97 outback's headlamp lens' are
getting pretty dull, especially on the driver side (probably because
the right one was changed when my wife smashed up the car). the lenses
seem to have very fine surface scratches.. Obviously it's from driving
the car. But, does anyone know of any way to polish these out? I don't
want to start experimenting myself. I don't have the $230.00 for each
side at this point if i really screw them up.

thanks for your recommendations!

Kevin

I used to use toothpaste to polish up a plastic watch crystal.

Novus plastic polish does a great job on this.

You could also wetsand them with a very fine grit sandpaper.

Either way, the dulling will go away and then come back in a few months
or so. The only real way to get rid of it is to start from scratch with
a new lense.

Some cars' Euro and Japan spec versions have glass lenses.(they don't
have CAFE laws) If it gets bad, maybe try to replace from overseas
wrecking yard.

What about Scotchguard Paint Protection? I know most paint protection
deals are scams, but this is an film that you apply to the car. It
should work fine on a headlight. The ad even features the clear
headlight lens from a Subaru Forester:

Not sure it would work on the lenses due to heat. Besides. the material
comes precut for your car and is a little pricy. There ARE however
plastic protective film covers for fog lamps so you may have a good idea.

Not to nitpick, because you might be right, but the most common
application for 3M's paint protection film is on the leading edge of a
hood (rock protection). Think about how hot a dark-colored hood gets
on a sunny summer day -- safe to say hotter than the clear plastic
lens of a Subaru headlamp.

Good point. Perhaps it isn't offered for some simple reason as it may
violate some DOT or other laws concerning 'safety equipment'
(headlights) being modified/altered.

Hi Kevin, All!

I have recently noticed that my 97 outback's headlamp lens' are
getting pretty dull,

Put a buffing wheel on a drill, or better yet an angle grinder, and
buff 'em using the "blue" abrasive (designated for plastics). Be
patient, and use light pressure; if you get overly ambitious you will
overheat and smear the plastic lens.
If you do this right, you can probably get them to
"nearly-as-good-as-new" condition. Hope this helps.

ByeBye! S.

My 97 Outback has the same problem with the headlight lenses becoming cloudy
looking. I found this link... http://www.miata.net/garage/lenspolish.html
