Headlight Rejuvenation

A friend of mine came up with this and I thought it worth sharing.

I don't know whether you've had the yellowing headlight problem where the plastic cover gets attacked by UV and becomes yellow.
My Daewoo (10 years old), Anna's Holden (10 years old) both have the problem. I've tried a few methods of cleaning it up. There's some stuff called Plastix which is about $16, a cream that you polish the light with. Certainly made a big difference returning the lens to about 90% clarity but it didn't take long until the yellowing started to reappear. The headlight shown below (top picture) has been cleaned a few times this way.

I saw that Repco had a kit for rejuvenating headlights. It's a bit more complicated. Basically you sand off the crap with sandpaper, gradually getting finer and finer. When you have finished sanding the headlight cover is nearly opaque. Then you use two different cleaning rags to drag any sandings and dust off the lens. Then you heat the lens with a hair dryer and then spray the clear headlight protection stuff on and Bingo! The lenses become crystal clear instantly. A couple of coats of this stuff and you're done. The results are fantastic. I'm now waiting to see how long it will last. Apparently the clear spray has UV protectors in it so I'm expecting it to last a while.

The bad part about this story is the cost. I paid more than $60 for the kit. It consists of two sanding blocks, 4 sanding sheets, a couple of small tack sheets, some brown paper to prevent overspray, some masking tape and a can of spray. Apart from the spray you get about $6 worth (max). So is the spray worth $54? I'm looking to see what it is worth without the kit but I'm betting it would be about $14. So the kit works well but is an absolute rip-off at its current price. If you can't get it separate at Repco I'm going to get some UV protectant clear spray and try it on an old headlight to see if I get the same results.

Picture 1: A previously treated with Plastix headlight before trying the new stuff. (It's not as bad as one that had never been treated.

Picture 2: This is the treated headlight after spraying the clear spray onto it. Comes up like new.

1968 MGB Purchased already dis-assembled which is why I'm often ignorant about what some parts are, and even more ignorant of where they go.

I got the same results with a Turtle Wax kit I bought for about $7 here in NY. I did it on a Saturn that looked like the headlights were covered with mud. I didn't take any pictures but the results were impressive. It was my friends car and she didn't even realize how bad the headlights were until I did one and showed her the difference. She had the car so long she didn't notice they had become so dulled. She said when she drove it after I did the lights she kept thinking her high beams were on because it was so bright.

Any good rubbing compound will do the same trick and following it up with a coat of clear or two will keep the yellowing at bay for quite a while. This reduces the cost significantly.

Anthony,
What product do you use for the "coat of clear"?

Typically a spray can sold for doing paint touch ups at any automotive supplier works fine for me.

Sorry, I could have been a little more "clear" in how I described it...

I sand them thoroughly with 500 grit paper on an orbital sander and spray two coats of automotive clear. Holds up really well. Buffing works well, but just doesn't stay clear as long as clear coating.

Never heard of that brand........Google shows 3M $15.99, Meguiar's $19.97-$24.99, Sylvania $24.99.........Fritz is $133 but not sure I'd pay that much.....

I had some severely clouding yellowing headlamps on my 01 Mustang and my 99 Chrysler LHS, and I tried Plastix which was a hug waste of money. I bought the 3M kit with the sanding discs you attach to a drill, and it worked perfectly. The problem with Plastix is it can't get rid of the coat of damaged plastic on the surface. You pretty much need to sand it off. I think the 3M kit was like $25 here in Canada, so it's probably only $5 in the States

You are all on the right track. At the factory and professionally we use a clear coat that is neither solvent or water based, where that base evaporates out as it dries. The factory coating is cured with a UV light like the little purple thing the dentist cures your fillings with or the light the "nails" ladies use on your wife's custom finger nails.
