So I figured I’d throw this DIY up on here, as I feel most of you guys could benefit from it.
I like this DIY method much better than any kit you can find because unlike restoration kits, this method restores the UV coating that comes from the factory. For those of you that have ever buffed and polished old headlights, you’ve noticed that after a year it gets worse and you have to redo them. This method will save you that trouble.
Following these steps, you can go from this (Oxidized, hazy, unsafe):
To this (clear, polished and bright):
To begin, you’re going to need a few supplies.
-Wet Sand Paper 500/800/1000/1500/2000
-Random Orbital Buffer (Or some really strong hands/fingers)
-Polishing compound for plastics
-Mineral Spirits (smallest container you can get at Lowes)
-Helmsman Spar Urethane - Clear Gloss
-Painter tape (if you going to do this with you headlights still on your car)
-Shop rags (incase of any spills)
-Scott Blue Rags
Now that you have all your supplies, you’re ready to start.
Step 1:
Begin wet sanding your headlights, starting with the 500 grit and working progressively up to the 2000 grit. Be sure to clean the headlight in between grits to clean any residue and grime. I used Windex as a lubricant instead of water, as it dried quick and was easy to spray.
Step 2:
Once you have wetsanded your headlights with the 2000 grit paper, you’re ready to buff the headlights with the rubbing compound. This will give your headlight lenses a nice surface. If you’re using the random orbital buffer, be sure to keep even pressure across the headlight.
Step 3:
Clean you headlights with the mineral spirits using a Scott towel. Do not touch the lense after doing this as it needs to be oil free.
Step 4:
This is the step that sets this process apart from other products.
In a mixing cup/red solo cup, mix 2oz of Spar Urethane with 2oz Mineral Spirits. Mix well until both liquids are combined completely.
Using a Scott towel, fold the towel into a small square and dip the towel into the mineral spirit/urethane mix. Do not over saturate the towel.
With the saturated towel, carefully and slowly apply the mixture to the lense of the headlight. Be sure to evenly distribute the mixture over the entire lense. Any drips can be cleaned up with mineral spirits, and if you apply too much simply wipe away with the mineral spirits and apply the mixture again.
Why use the Spar Urethane? It has a UV coating that, when reduced with mineral spirits, will give your headlights a UV resistant (factory) coating, as well as a tough/glossy finish.
From what I have read, this finish will last up 3-4 years with regular driving before needing refinishing (mineral spirits and reapply the mixture).
I’m very happy with the results and hope that you guys give it a try, it’s worth it!
Thanks guys,
Chris
