Dunno how this kits works, but if you want to try it I have a bunch of different polishing compounds that I use for fiberglass repair. Probably the same sort of thing you do to remove UV and pollution oxidation on WilderNests and boats (fiberglass gets chalky with sun exposure, so you need to do a polish and wax once in a while). I even have a random orbit polisher so you don't gotta do it with elbow grease.

I have done this on the T100, the cruisers, and other vehicles. I have the best luck with wet sanding with 1000, 2000, then finally 3000 and finishing up with a compound, like plastix.

tape off the surrounding trim, and go to town.

I have used just compounds, but it doesn't work like sandpaper. I used a "mothers ball" with the compounds. I tried my regular buffer, but it didn'w work that well.


Believe it or not, whitening toothpast works as well.

My dad tried this, or something similar, that you can buy at Checker or Napa...Said it made them marginally better. He didn't want to spend the :twocents: on new headlamps nor the :twocents: on a second kit so I'm guessing it made them good enough so he could see at night again (I hope).

When I was helping him research this I read somewhere that sometimes more than 1 kit would be necessary (i.e. 1 kit per light)

I polished the headlamp covers on my 9-5 and a happy with the results. The kit I used was two grades of wet sanding followed by a polishing compound followed by a UV protector. Supposedly without the UV protection, the haze returns quickly. The kit was a bit overpriced for what was in the bag but it did save a bit of running around looking for stuff. It called Crystal somethingorother.

Your glass on the 80 yellows?

I hate the plastic lenses on new cars.

On my MR-S the right headlight seems to have suffered solvent damage and it gets hazy.
The mequires plastic polish makes it look like the left side for a couple months. Then I have to buff the lens again as it starts to cloud up again. (like stated above, It is a short term fix.)

New headlights on the MR-s are $140 for the pair. I'll keep buffing occasionally for now.
(Apparently Toyota headlights are pretty inexpensive compared to other Marques.)

No, not the 80 on the Taco... I may just order that kit and see what it does, I'm sure it will be some improvement.

I've done many Subaru's with similar kits. I generally started with 800 grit wet sanding with something like windex. Moving my way all the way to 4000 grit progressively. Then the buffing compound, finally the sealant with the kit. I had really good results but it takes some time and elbow grease. Its easy to rush it and be disappointed in the end.

if our lenses are pitted you will need more than just the buffing compound to make them new again. I recently picked up a kit from NAPA for $20 to do the lenses on Marianne's Subaru. I have not opened it up yet but it looks more like the commercial kit I was accustomed to using at Avalanche Automotive.

It is not haze from your headlights it's smoke from the Cali fires and the western slope fires. LOL JK

I ended up buying the 3M Headlight Restoration kit. Was $17.99 on sale, so just under $20 out the door + tax. http://shop.advanceautoparts.com/webapp/wcs/stores/servlet/product_Headlight-Lens-Restoration-System-3M_7100089-P_N3312W_T|GRP2074____

Overall I am pleased with the results. Total time was 2 hours, and that included time to remove the grill and corner lights, drive the 80 to Advanced Auto Parts & back, and do the job.. which involved going through 4 batteries on the cordless because it's faster than getting out the real drill and an extension cord.. :rolleyes:


edit: picture of the kit, and a final "before" picture...

actually now that I look at the pictures I'm pretty psyched- giving this product a :thumb: and a good use of $20 and 2 hours.

That is a huge improvement. Did the kit include a UV protectant?

Nope. No UV protectant but the directions suggest for longer lasting results to buy more 3M products, like a plastic protector, etc. so maybe that has it. This is good enough for me though, and I can't see why it won't last for a while since the polycarbonate lens didn't change at all, I just ground off the yellow/scratched part. We'll see what happens though.

so how's this working after about a year?

Tim's looked like it had more of haze and outright damage than yellowing. My Camry had yellowing and I had to repeat it every 3 or 4 months and they looked new again. Now the 3M stuff I used only took 5 minutes per side.

The tint is back a little, but still way better than it was, they're still clearer than before but the yellowing is beginning to return. I was just thinking about this the other day actually, about maybe doing it again. Only problem is there's now a big bumper in the way so the access is a bit more difficult :o.

Here's a pic from 2 minutes ago, through my office window.

Used the kit in the first link on my dad's Camry...He said the difference was amazing. Of course I also installed some Toshiba HIRs for him at the same time as well :)

He tried a different kit previously from Checker with little success.

I went REALLY overboard and started with the most aggressive grit so it took quite awhile. But in the end I thought the headlamps looked "new"...We'll see how long it lasts but it's been about 4 months and so far so good.

well cool, my Tundra could use some headlight sprucing, and if it can go for a year or more then I can handle that...:thumb:

I'm sure the crystal clear headlights are tougher to do, but I have done many of the older plastic headlights with a cheap orbital buffer (the kind you can stall if you push too hard) and a clearcoat-type rubbing compound (very fine grit). I can get 90% of the haze/ugly to go away, and if the vehicle isn't outside most of the time, it takes a long time to come back. I doubt any wiped-on 'UV protectant' is really going to last very long. I just rebuff as needed. 5-8 minutes per side, and use masking tape to protect the paint/grill around the lights. Quick, cheap, easy. Makes any beater car seems like it's worth more when you sell it ;-)

Piggybacking on nakman's thread:

Well, I bought the 3M kit from Autozone, it was about $20. Spent a couple hours messing with it tonight, including doing laundry and stuff, and am pretty pleased with the results so far. You have to have a drill, a terry cloth, and a spray bottle with water. I was timid about doing this procedure, but thought if some goober who buys stuff at Autozone could do it, I could too. The kit comes with 300 and 800 grit sandpaper and a 3000 grit pad as well as a buffing sponge, rubbing compound and masking tape. You start with the 300 and work your way up, finer and finer. It's really easy to do and I'm impressed with the results, especially with my passenger side light. My driver side light was worse to start with, and I think it needs some more work (tomorrow), but it has showed pretty significant improvement.

I have just started wetsanding mine with some 1000 every once and a while.. I only had time to do one side last time, and the difference with the lights on is amazing.

I might look into some kind of UV protectant - it can't be that expensive and may save the headlights so they don't have to be redone so often?

I have been using a product call plast-x polish, that works really well. It's available at autozone. I use it for the motorcycle screens and such, it works.
