DIY: Polishing Headlights with Toothpaste

https://www.youtube.com/watch?v=wD0EcKrfA7M

Video Tutorial on how to polish your headlights with toothpaste. This method does actually work, but it can be very work intensive compared to my other method of wet sanding. This works similar as to applying a polishing compound because toothpaste does contain an amount of grit/abrasive material. If you do have any stone chipping or heavier scratches in the headlight, toothpaste will not remove that as this method takes the contour of the light surface. Wet sanding on the other hand does remove more material and skins over the surface taking down any high spots. Your choice of wax can also be applied in the end to protect the lights over a longer period of time and give them a deep shine. Toothpastes that contain more of a grit/abrasive feel tend to work better than the types that don't. The outcome of the final product will depend on how much time you are willing to spend, what type of toothpaste you are using, and what the severity of the hazing on your headlights is. This will also work on other lights around the vehicle such as fog lights, parking lights, and tail lights. This process will last for almost a year until they need to be revisited again (when applying a protective layer of wax).

Tools/Supplies Needed:
-toothpaste
-spray bottle with water
-lint free cloth
-wax and lint free cloth (optional)

Procedure:
-be sure the wash your vehicle or at least the front of your vehicle to ensure there will not be any debris contaminating during the polishing process
-using your choice of toothpaste, apply it to a lint free cloth
-spray the headlight with a mist of water if it dry, this is for lubrication and increase a finer polish
-rub the toothpaste using the lint free cloth into the light, ensuring you get the whole surface of the lens
-use vertical and horizontal directions, as well as circular patterns
-apply more toothpaste and water when needed
-when satisfied, rinse the front of your vehicle off with water
-make sure the lights and area around is dry, then apply wax to increase the shine and protect the lights over a longer period of time (optional)

DIY: Headlight Restoration using Clear Coat

https://www.youtube.com/watch?v=HgNNMj0gGbA

Video tutorial on how to refinished hazy/foggy plastic headlights by applying clear coat. This is intended to be a long term method compared to the other two methods which I have done in the past that was the wet sanding/polishing method and the method using strictly toothpaste. The headlights do not need to be removed from the vehicle or disassembled as I have shown the in the vehicle. Removing the headlights from the vehicle does help to eliminate the chance of any over spray from the clear coat or adhesion promoter landing on the paint which would need to be cleaned afterwards.

Tools/Supplies Needed:
-800 grit wet/dry sandpaper (if your headlights are severe)
-1000 grit wet/dry sandpaper
-bucket of soapy water
-isopropyl/rubbing alcohol
-clean lint free cloth
-tape
-paper
-adhesion promoter
-lacquer/clear coat

Procedure:
-if you decided to remove your headlights, start with that step first (headlight removal varies between makes/models of vehicles)
-wash the headlights thoroughly to ensure no contaminants will get into the wet sanding process
-tape off around the perimeter of the headlight lens or vehicles paint to protect it (optional)
-ensure the lens is always well lubricated during the wet sanding process using the soap water
-if your headlights are severely hazy/foggy, wet sand starting with 800 grit and finish with 1000 grit
-if headlights are mildly hazy/foggy, start and finish wet sanding with 1000 grit sand paper
-once satisfied, wash the headlight again to ensure there are no contaminants which would affect the lacquer/clear coat
-once headlight is dry, wipe it down with isopropyl/rubbing alcohol
-tape off the areas you do not want any lacquer/clear coat on
-wipe headlight lens down again with isopropyl/rubbing alcohol, do not touch the lens with your hands (oil from your skin can cause imperfections when apply the lacquer/clear coat)
-use the adhesion promoter to ensure there will be maximum adhesion when applying the lacquer/clear coat
-once adhesion promoter has setup, then go ahead and apply the lacquer/clear coat
-lacquer/clear coat can be applied in 2 coats if you are not planning on wet sanding afterwards
-if you are planning on wet sanding to a polish afterwards, apply 3 coats to ensure there is enough material for the next process
-wet sanding tutorial located here https://www.youtube.com/watch?v=RBENX1uvZak
-be sure to remove any paper or tape after about an hour of setup time
-let the headlight fully harden in the sun for at least 24 hours before the wet sanding and polishing stage
