WD40 VS 3M | Best Headlight Restoration Method?

[@timpowers3943]

I used chrome polish and a white scrub pad. Buffed off by hand and it's like brand new!

[@XBKLYN]

The WD-40 lubricant flows into the miniature valleys that we see as scratches. Since oils have a similar refraction coefficient to plastic the scratches appear to fill in and the lens seems to clean up. Your clever experiment of wiping off the WD-40 with a degreaser shows exactly why this is a temporary measure. Using oils to coat scratches on a number of different materials is actually a very old restoration trick....hey, whatever works!

Just did yesterday: Colgate regular toothpaste, baking soda, regular (table) grit-sized salt. Smooth on towel and scrub until you are happy. Leave on 30 minutes. Wipe off with moist towel. Repeat as needed. Update: adding a little (tablespoon) Pepsi/coke to the mix does strengthen it(credit RP enterprise comment) Just did the other car. I’m getting ready to wipe with the WD-40 per commenter on this post and another KZbin video to see if it shines. It has been mentioned to spray with Plexus after cleaning to prevent it from getting on there. Spray about 3 times a year. I’m planning to purchase some.

Except the sanding causes microscopic fissures that will eventually cause cracks and you'll need to replace the assembly. Clear Coat is NOT for headlamps. Best choice? Use this on a new car: Meguiar's G17804 Keep Clear Headlight Coating. Spray it ever year. (Pick something like every Valentine's Day, so you remember, and it's the same date.) If your car is older, and it's already yellowed, use the sanding methods, but only once, so you don't wear down the plastic. Then, forget using the coating in the kits (many make them; 3M, Sylvania, etc.) because it's just another Clear Coat product, and will eventually wear off again. The Meguiar's doesn't break down. P.S. Before I learned all this, I was just a kid, and used clear nail polish. I figured it out myself, and it worked, but took forever, and still wasn't as good as Meguiar's.

[@cspringer333]

Used the 3M and it works great. You can use your drill with the attachment that comes in the kit. Don't waste your time covering up the problem because it won't last (maybe not even a couple of days). The different grit sandpapers do the job.

[@gravemind6536]

I sanded down a really bad pair of headlights on a mk5 Golf it was a little lockdown project in 2020. I used 3000 grit sandpaper then 5000 and then 7000 after that I used T cut polish and finished off with turtle wax polish 90% of the fogging was gone and my mum was simply amazed. She said she kept accidentally thinking her full beams were on when actually her headlights were performing how they should. They were really bad so I could not remove all the fog but all in all I saved her £120 on a new set with only £15 worth of gear.

[@TD402dd]

Sanding the old plastic will cause it to create very tiny cracks. Eventually the cover will fill with water. My Lincoln LS had a new cover added, so the repair center used a polishing wheel to clean the other lens. Five days layer it leaked. There are some better things available that is a type of cleaner polish that brings back the clarity and it has a finisher you put on by hand once per year. That was three years ago.

[@gravemind6536]

Yes if you sand them too much they are permantly fucked as the clear coat is gone the sanding method should only be used once and from then onwards prevent further residue by waxxing the lights every season and keeping them polished.

[@Sammasambuddha]

WD40 works fine. Just don't wipe over it with degreaser or window cleaner afterwards. It will have to be done regularly because rain and car washes will remove it, but a can of WD40 is pretty cheap and you can do both headlights in about a minute using a cloth rag or even a soft paper towel.

[@MegaMiemiemie]

[@zaineridling]

*Know your chemistry.* Acetone (nail polish remover) reacts negatively to the polycarbonate headlight cover and will PERFECTLY clear your headlights anywhere from 7-12 months of direct sunlight (UV rays). The only reason for sanding them (if needed) is if there's a coating such as clearcoat on them. Unnecessary unless you just want it. 👍

[@waldipup9010]

I've rerad to NEVER use nail polish remover , just pure acetone ,as the npr has additives .

My husband used Off spray for mosquitoes. Worked perfect! I used a Mexican product called Ariel. It’s soap. I wet the headlight, and in a cloth, I sprinkled the soap and rub the lights. It worked perfectly for my Maxima headlights. I tried W-40, didn’t work.

Actually, you can get "clear bra" or similar transparent material (at tint shops) to cover your lights. It's cheap and replaceable if damaged by rocks. I get every car I own front wrapped, even the side mirrors. Works wonders.

WD40 is a great water displacing anti-corrosion product. Not so much a headlight restoring cleaner, as you demonstrate. Also using degreaser and window cleaner on PLASTIC headlights will cause the haze and yellowing to accelerate. After the polishing, good job on that, using a UV protecting coating is advisable.

The lens have become really yellow and we were thinking about buying new headlights. I am thinking about trying something like this 3M product first.

[@gravemind6536]

WD40 will not work it will just mask the issue for 2 days tops depending on climate. If they are really bad polish will not be enough you will need to sand them down then polish them and then wax them and keep waxing them every season to prevent fogginess returning.

Faster fix that works and lasts 1 sand with wet 1000 grit paper with soapy water 2 now use 2000 grit wet sand again 3 rinse off with clean water and dont touch with your greasy fingers afterwards 4 use paper towel to damp dry and now it will show a fine milk finish with no blemishes of old coating left behind or redo step 1 and 2 to get it better. 5 once done get a good fine brush and a small can of liquid plastic Varathane 6 Best finish without any runs is headlight out and facing up and brush on an nice thin coat of varathane. 7 will dry to tack in under a hr or 2 but if one careful you can reinstall or let dry overnight in a place with low dust etc and good eg is stash in oven hehehe. Just dont turn on by accident. This will develop to a factory glass hard surface in few days lasting many years. 8 Headlight will be back to perfect clear factory gloss finish that can be redone in a few years if needed note : i have done fast on vehicles for sale still mounted and got perfect results on all signal lights doing the same way
