Anyone tried the new headlight kits?

[Thomkirby]

I have a test vehicle I want to try to correct the headlights with one of the new kits from Griot's Garage or Diamondite. Does anyone know if they would work for turning these lights back to clear?

I am proficient with sanding method but would like to try these new chemical based kits to see if they really do work without the sanding step.

My test vehicle was done over 2-years ago and has yellowed:

Will the entry level kit work or need the kits with sanding step?

I used a Griot's Garage headlight resto kit on my ex's 2007 Mazda 6 about 4 years ago. The car was traded in Dec of 2019 and after 2 years they still looked great!

I see Griot's Garage has a new ceramic kit in 2 levels of restoration needed, I'd have no hesitation to use one of those kits as I'm sure Griot's Garage made them even better[emoji106][emoji106]

I should tell you these lights were so bad you had to use the brights to drive at night, so not only does it make the car look better but SAFER[emoji6][emoji362]

Those don't look that bad. I wouldn't waste your money. Just hit them with a wool pad and some compound; finish off with foam and polish. Nobody that I've seen makes a good sealant. I would just use some leftover coating and redo in a couple years.

So a kit with nothing more than some wipes will actually remove the hazing and yellowing of the lenses? The spray product in the Griots kit appears to be the final sealant/coating.

I've never sanded lenses, but have used a polisher and the polishes included in the Wolfgang headlight kit. I thought that yellowing/haze would need at least some sort of abrasive polish to remove. On my daughter's Mazda3 it's pretty stubborn.

The new Griot's kits come with ceramic wipes in place of the spray on clear coat the old kits came with.

I actually have the new moderate kit that I got for the headlights on my gf's car (Mazda 3). I may try that out at the end of the month. Will report back with before/after pics.

You spray water constantly on it while sanding, wipe it away and dry, tape off the whole area real good, evenly spray it on and let dry in the sun for a couple hours...done[emoji106][emoji106]

Interesting. So the squares are actually a really mild sandpaper?

I should add that these headlights were also very dry and crusty as well as faded[emoji118]

If you are not applying any UV resistant coating to the headlamp after the restoration process then they will 100% fail again in a very short period.

I recently tried out the Cerakote restoration kit on some faded 2012 Cruze headlamps. This kit while claiming to be very easy proved to be a challenge for me. During the sanding steps I just couldn't get uniform coverage. Parts of the original hard coating from the factory were impossible to remove without putting in a ton of pressure on the sanding discs. So because of this I ended up installing deep scratches into the lens that I was not able to level out with just the two coarse grits supplied. The final step was the ceramic coating wipes and while it was supposed to be a self leveling coating which is used to fill in the minor scratches left behind, it didn't do it so well and left a not so clear lens.

While my experience is primarily operator error it demonstrates that the skill level of the person performing the restoration and the quality of the kit determines the outcome. And its important to note that while visually looking at a lens that *appears* more transparent does NOT indicate that it will perform like a new headlamp. Because lets not forget that headlamps are safety devices and we need them to provide at the highest level possible.

A study done in 2018 by AAA regarding the performance of lens restoration and aftermarket replacement headlamps revealed some rather interesting data. For the restored sample headlamps, the beam performance achieved was only 50-80% of OEM performance. This means that while they *looked* like newer clear lenses they did not perform like brand new dealer OEM lamps.

Here is one of the samples, an Altima headlamp, and the measured beam performance in a birds eye view of the scan. Though the restoration improved the beam, it still was not as strong as a new OEM lamp.

New OE lamps are not always cheap but they do guarantee the best performance between a restoration kit and an aftermarket replacement.

Did that study happen to mention what % of the OEM reference is achieved by "good" aftermarket housings like say Depo or TYC? I completely agree that new OEM housings are the way to go (and the very knowledgeable people on the Daniel Stern Lighting and Candlepower forums very emphatically support using only OEM housings) but they can be cost prohibitive - for example, OEM housings for my 4Runner are around $250 per side plus tax and shipping.

You're lucky if they are only $250. When you get into HID's and LED housings, the prices are substantially higher. I think the the HID housings on my car are over $2000 each. Fortunately, they age well and I will polish them when needed.

Absolutely. I forgot to include the critical detail that like the F150 in question my 4R is also a 2008. I don't consider an '08 to be all that old and it's certainly worth fixing properly but $500+ for new OEM housings could be hard to justify for a lot of people if there's an aftermarket solution that works "well enough" for 1/3 the cost.
