Besides the 3 primary packages or approaches to detailing cars, we also covered Extreme Headlight Correction. I borrowed my business neighbors Ford Escape as the plastic headlights are so far neglected, they've turned yellow with oxidation.
Also just to note - these are OEM Clear Coated Headlights.
You cannot tell due to the mass oxidation. As we started to sand, we could see where the OEM Clear Coating had degraded and left a jagged line where coating was present and coating was missing.
The Mike Phillips Method for FAST Headlight Correction
I've never seen anyone else do this or teach this until I started teaching it at our classes. Feel free to borrow this technique if you like.

ape-off and Protect
When sanding headlights using LOW GRIT discs or sandpaper, it's important to place at least 2 layers of protective masking tape over any nearby paint, plastic or chrome surfaces.
Why?
Because if you accidently sand the nearby paint, plastic or chrome, it can be pretty much impossible to recover from the damage.
Pop the Hood
This is a simple technique that completely removes any paint away from the headlight and thus the sanding process and that is to simply pop the hood.

The lowest grit I had on hand was 500 grit - I wish I would have obtained some lower grits like 180 or 360 grit. For most headlights, 500 is more than enough to do the first step. But for headlights this neglected WITH an OEM Clearcoat over the headlights that has failed, then it would be faster to sand off 100% of the OEM Clearcoat using lower grits like 360, maybe even 180.
For this process, the class will machine sand starting with 500 grit and ending with 4000 grit. In reality, anyone talented with a wool pad on a rotary polisher with a quality compound can easily remove 2000 grit sanding marks out of plastic headlights. What my normal practice is - show the MOST steps and then let everyone figure out how many steps to do when they return to their detailing world.
It's Go TIME!
After a quick demonstration, I turned the class loose. By sanding with 5 different grit levels, this ALSO provided plenty of hands-on time for each person to learn how to machine sand headlights using a rotary polisher.
And here's the secret to sanding with a rotary polisher without GOUGING the plastic and that is to use 2-3 foam interface pads between the backing plate and the sanding disc.
The design of these Ford Escape headlights made sanding challenging but the class powered through.
See the foam interface pads?
Teamwork makes the dream work!
Removing the Sanding Marks
After all the sanding step, the next thing to do was to use Dr. Beasley's CoreCut with a wool pad on a rotary polisher to cut or remove the sanding marks. Sorry, no pictures but this was in fact the next step.
Removing Holograms
Fiber pads on a rotary polisher ALWAYS leave holograms in the surface, even headlights. To remove the holograms and perfect the final results, the class followed the rotary step using gear-driven orbital polishers with Dr. Beasley's NSP 150 with Buff and Shine yellow EdgeGuard foam polishing pads. If you don't do this, not only will the holograms be visible when the car is outside in bright sunlight, but you will also leave the plastic surface
MORE OPEN and this leads to faster deterioration.
Seal the Deal
After the polishing step, the class then used the Dr. Beasley's Headlight Coating Kit to seal the headlights and protect them from UV rays and the elements.
And here's the final results!
Now these headlights not only look better, but driving at night will be much safer.
Not bad for severely neglected headlights that are 20 years old!
Great work everyone!
