Pros: Very inexpensive and effective product to make your headlights look and perform better.
Cons: Takes a little time and must be done outside due to water usage.
This product works as advertised and better than I'd hoped. Completely restored my headlights to like new condition within about 30 mins. of effort. Recommended it to my coworker and he had the same WOW experience on his vehicle.
The product contains everything needed for the process which consists of wet sanding the headlight surfaces and then recoating them. Just take your time and read the instructions thoroughly and you should have no problems.
After washing the headlights and masking the area around the headlights with the included tape I sprayed on the activator product which was step one. The old yellowing on the lense surface actually started to break down and run off the surface with the spray which I found amazing.
Continuing to follow the instructions for sanding and rinsing the surfaces I got a little concerned prior to the last step. The headlights were very cloudy in appearance due to the wet sanding process. However, immediately upon starting the application of the new protective coating I was amazed at how the surface became immediately clear like a new headlight. Careful application of this coating isn't too difficult and after sufficient drying time your headlights will literally look like new units.
Let me emphasize that reading the directions carefully is key. The steps are not difficult and the instructions aren't hard to understand I just got distracted by some neighbors in conversation and actually switched the materials to use for the second and third step. Fortunately there was enough of each for me to go back and redo those steps correctly and everything still turned out great. I'll try to update after some time has passed to confirm the durability claims but I have a high level of confidence that this is one of those products that performs as advertised.
