I used the kit on my 92 Legacy. I had actually already picked up a
pair of headlamps at the salvage yard (which turned out would not fit)
but mentioned the yellowed lens while at Advance Auto and the salesman
mentioned the kit. I was skeptical but had nothing to lose (since, at
the time, I thought the salvaged headlamps would fit). Worked great
but I did have to re-wet the polish compound to keep sanding away the
yellow (I probably sanded more than I had to but I was going to be
damn sure I had done a thorough job).
Besides getting rid of all the yellowing (which seems to be on the
outside of the lens where you sand it off), it gets rid of dulling,
too. To be truthful, the restored headlamps don't look perfectly (I
have another new Subie for comparison) but they're damn close. If I
had tried the kit beforehand, I would've never bothered picking up the
salvaged headlamps. Before hearing of the kit, I was going to try
some 1200 grit, or finer, sandpaper and some marine polishing compound
but finding the lexan clear coat used by airplanes for their
windshield was turning out to be a problem. Some folks simply used
clear coat spray paint, like what you paint your body panels with, but
I doubt that would survive the high temps from the headlight bulbs.
The OP mentioned pits. So much sanding would be needed to get rid of
pits that it is likely the lens would be damaged or warped (and be out
of focus). While not quite as old as the OP's, my 14-year old
headlights don't have any severe pits and neither did those that were
salvaged. The OP must drive on gravel roads a lot, or an area when he
is unlikely to get stuck with road resurfacing that uses stone chips
(which can also cause flat tires).
