Fellow Grand Cherokee owners,
I was going to fork over about $180-$300 worth of new plastic headlight
housings for my 1999 grand Cherokee.  My old ones were a mess and light
barely came through these nasty, yellowed, funked up plastic lenses. A
friend of mine turned me on to Crystal View headlight restorer kit.  I
bought the kit at Advance Auto for $20 (cheaper than the web-site which
charges $23.96) http://www.crystalviewchemicals.com/

I have to tell you that I am always skeptical of this kind of stuff.  Much
to my surprise I was very very pleased.  I spent about an hour wet sanding
the passenger side headlight housing (it was a mess) and then I put the
final protective coating from crystalview on the headlight housing.
Unbelievable..the housing looks brand new and the lenses are crystal clear.
I have no idea how long it will last, but they say it's a permanent fix and
it comes with a warranty (whatever that means).  We'll see.

So, if your plastic lenses/housings are all gunked up, give this kit a try.

As I look at this posting I can see how one would think I work for
Crystalview.  I dont.  Just trying to help my fellow Jeep owners fix a
crummy chrysler product. Like the front brakes on 1999 Grand Cherokees.

I think you forgot your MAF anti-spam id.

That kit does work.  There are other options but some of them I'd
try on a junker lamp first.

Personally I wouldn't use the brakecleaner trick, but toothpaste is just a simple mild abrasive and does work.

Good writeup from the folks at permatex.

Me, I used rubbing compound and ultra fine cutting agent, followed up with a buffer and some clearcoat for plastic.  Still working
well.

Doug,
do you think the coating in the CV kit is just clear coat?

Yep.

The reason you use it is to prevent the plastic from re-oxidizing.

Perhaps you are not... or perhaps you are.  Possibly you went to all the
trouble to locate the web site and post the URL sheerly out of the
goodness of your heart.   And possibly the former Finance Minister of
Nigeria really does have a check for me.

However, there are several headlight restoring kits on the market, all
work to some level of effectivity.  The better ones have a protective
finish, which must be renewed periodically.  Some, e.g. Mothers, come
with their own buffing tool to make it easier.

I'll add one comment, watch out for crown brand parts.  They are often sold as "exact replacements" but unless your planning on
selling the Jeep, go with OEM.  The crown parts don't last worth squat.

Lon,
sorry friend, no check from the finance minister of Nigeria.  Just trying to
pass on some info that might save people some money.

As far the CV restorer kit, the only thing I didn't have was the coating you
put on after you buff the lenses with polish.  If you can find the special
coating, you just need to buy your own wet sandpaper and you could probably
do the job for $10.  All that said, I still put in two hours of sanding and
polishing on these lenses.

I have used the permatex plastic polish with great success.  actuually, a wet
sand first if its really bad, follow up with the plastic polish, then the
clear coat for polastic and your good 2 go!

So how do you apply the clearcoat?  With a sprayer or a fibercloth?

Pretty much anything works.  UV safe plastic paints tend to last longer,
but you'd want to really mask off the front and avoid winds, or pull the
lights for the refurbish.

I have heard that wiping the lenses down with acetone-free nail polish
remover does the job. Haven't tried it, all my vehicles have glass
headlamps.

That's one of those methods I've read about but would not try unless
it was on a junk lamp.  Same with using brake/parts cleaner.
