Brightening up an older car

 There are few things that make an older car in otherwise good condition look tired than hazy headlights.

For the past 30 years or so, virtually all cars have come with clear plastic headlight lenses. They give manufacturers greater latitude in designing vehicles' front ends, but over time, the sun and road grit conspire to make those lenses look dull, yellowed, and hazy. In the worst cases, they are almost opaque, diffusing forward illumination to make the lights considerably less effective.

One might think the simplest solution is just to replace the headlights, but this is an expensive proposition that can cost in the hundreds of dollars, and there is really no need for this, as the existing lenses can be polished and restored without a lot of effort. You can have this professionally done, but it is also a good driveway project that can be done in an hour or two, and for less than the cost of a tank of gas. 

A quick Internet search will bring up any number of home remedies, including toothpaste, to clear your headlights, but the one thing they all have in common is they don't last. You have to repeat the process every few months, and some store bought kits have similar shortcomings. 

I have tried kits from several different manufacturers on various cars, and the best of the lot seems to be one called Cerakote, which involves a three-step process that returns the headlights to like-new condition with no power tools required.

The kit purports to come with everything needed to do the job, but there are a few things needed that aren't in the box. Since it involves abrasives and caustic chemicals, it is advisable to mask off the painted areas around the headlights, just to be on the safe side, even though the instructions make no mention of this. Also needed is a container of water, such as a bucket or spray bottle, which the instructions do mention with regard to washing the headlights before beginning the process and for wet sanding them in step two. You will also need a roll of paper towels.

So, the three steps are actually four, if you include washing loose dirt off of the headlights and then masking off around them before beginning the process. We'll call that the prep step or step zero. 

The first step using items from the kit is to remove the deteriorated sealant coating from the headlights with the included wipes, labeled with a large numeral one on each packet. Because the chemicals on the wipes are caustic, you should wear one of the two pairs of nitrile gloves included in the kit, which provides a total of eight wipes, four for each headlight. The instructions suggest wiping in a circular pattern and changing wipes frequently as they take on a nicotine-stained hue. This discoloration will be minimal by the fourth wipe. 

After this first step is complete, wipe off the remaining solvent with a paper towel and discard the first set of gloves. The headlights will look clearer as you perform this first step, but they will become hazy again as they dry. 

The second step is wet sanding with the provided sanding discs and applicator. Start with the 2,000-grit disc then follow up with the 3,000-grit one. The kit includes two of each, one for each headlight. Sand gently in straight, horizontal lines across the headlight lenses and use plenty of water on both the sanding discs and the headlight surface; otherwise, you will likely scratch the lenses. The instructions suggest sanding for three to five minutes with each disc. 

After the sanding step is complete, rinse the headlight lenses off with water and wipe them off with a paper towel to remove any remaining grit, then dry them thoroughly. Use towels, a blower, or just let them dry naturally. The important thing is to make sure they are completely dry before moving to the final step of applying the ceramic clear coat.

This last step is where the magic happens. The ceramic clear coat finally gives the headlights a like-new finish and protects them from hazing over again. Put on the second set of gloves and be prepared to be bowled over by a strong ammonia odor when you open the packet to extract the wipe. There is one wipe for each headlight. The instructions suggest applying one coat of sealant in overlapping horizontal strokes, making sure to cover the entire headlight surface. This is by far the quickest step, but you will need to wait a minimum of one hour before driving the vehicle and don't touch the headlights while the sealant is curing. 

Once this entire process is done, you will have spent about two hours taking your headlights from hazy to amazing. They will not only look like they did when the car was new, but you will be able to see much better at night. And Cerakote guarantees these results for as long as you own the vehicle.  Of course the best part is the satisfaction of having done this yourself.
