Headlight Restoration-new UV sealant idea

This process is just what my cars need. Seems like a simple process. I have purchased and used the 3M Headlight kit, but longevity took its toll. The issue with the kit is the lack of a sealer.

Sent from my cm_tenderloin using AG Online

The 3M kit is great for removing the old coating, but doesn't provide a new one. If you regularly take care of your car, a periodic coating of a good synthetic wax or other UV blocking coating is better than nothing.

An alternative is to use the coating from a Sylvania kit. Would probably last a year, longer if you keep it waxed.

Anyone having issues with their headlights looking yellow?

Ive re-done my headlight 3 times now. Everytime by the first month or so its already yellowing.

You removed the old protective coating but didn't replace it with a new one.

Try keeping a good coat of synthetic wax on them after clearing. Better than nothing.

I've noticed some people on this thread mentioning "professional" products for protecting newly "cleared" plastic headlamps, but never a mention of where one might buy them. There are some thinly veiled mentions of "not retail" as though they are some kind of deep dark proprietary secret.

So is anyone willing to mention a brand name or a source? Or what they are, chemically?

ALSO, there continue to be claims for "oxidation removers" that clear foggy headlights without the sandpaper and abrasive approach. They cost a lot and seem too good to be true. Any attempt to find out what they really are, get the "proprietary, can't say" response. Anyone here know what THEY are? Other than "proprietary" or perhaps "Snake Oil?"

I'll respond to this. Professional coatings are manufactured by Delta Kits, Dvelup, Brite Lites, Medallion, Momentive, Speedokote, and others. They are termed not retail in that you can't buy a small amount to do a few headlights. You'll probably spend around $100 or more for their minimum quantity. They are sold to individuals providing restoration service, commonly people already doing detailing, windshield repair, body shops, etc. Some are wipe on, some spray on, some are cured with UV lamps, etc.

Most are either polyurethane based, or alkyd resin based. Some are 2K, some are 1k. Actual composition is proprietary to the manufacturer. There are oxidation removers available, but no magic. Most are strong solvents that were made for something else.

If you want more specific info, PM me. This is AG's forum and we must respect their guidelines.

Amen to that brother! I'd like to know also.

I've looked at a few of these and $100 is a very conservative number. Can you even purchase just the coating by itself? I thought you had to buy their whole system to be able to obtain the coating.....?
 
Well I can't believe I read through this entire thread. I've never done a headlight restoration but am intreguied. I have experience painting and detailing mostly House of Color products on motorcycles. I'm pretty much a weekend warrior when it comes to detailing. I wanted to thank all of you for sharing your insights and experiences especially Hot Rod. My 06 Lexus headlights are starting to fail and may be my first test subject.
 
Thanks to Ray6. A quickie search on the Internet finds that some of these brands do sell the sealer by itself. Most appear to require spray application and UV curing (sunlight or UV floodlight).

Good to know!

I'm not a big fan of restoration systems. It's better to think of restoration as task based.

And when I say restoration I'm also talking about acrylic (tail lights, turn signals, fog lights, emergency lights like the light bar on a police car) and polycarbonate headlights.

You need to do two things to restore a headlight; Remove the old, deteriorated protective coating applied when the headlight was made, and,replace it with a new one.

Fro removing the old coating, you can either strip it chemically, sand it off, or in a few situations use both.

Chemical stripping is simply applying the stripper and scrubbing off the old coating. Nothing special, and no tools needed.

For sanding, you can hand sand or machine sand. Machine sanding can be done with a drill (not recommended) or sander. The sander can be electric or pneumatic.

Will air or electricity be avai8lable where you're restoring headlights? If electric and no power available, you'll need an inverter or generator. For pneumatic, big honkin compressor.

Once the old coating is removed, you need to prep the surface for the new coating. This can be anything from wiping down with alcohol, to roughening the surface with 1500 or 3000 grit abrasive to provide good tooth for the new coating.

The final coat is the most critical. Use a real, professional coating. There are many to choose from. They're not cheap, but the actual cost per headlight is less than a dollar.

How to pick a good coating?

See what the pros use. How long to dry? How do you apply? Water based or solvent based? What's in it? Are there MSDS available? How long will it last? Do I need to tape/mask/spray/UV cure?

My approach is to not settle for any single system or product. If you're going to do restores for money, you need to be versatile. You need to be able to provide quick, inexpensive restores at one end, and more expensive looks like new at the other. I don't think any single system will do both.

To be a step above your competition, give your customers a written guarantee. This only makes sense if you're using a pro coating.

If you're just starting out, you need to fine tune your procedures and take lots of before and after photos. There's no shortage of defective headlights available,. You can start with friends and neighbors.

If you're going to work the lots or fleets, be prepared to do one vehicle for free. Prove your worth.

Another way to practice is to do free restores for charity groups. On the west coast, we have many; Salvation Army, Goodwill, Poly Klass Foundation, etc. They are more than willing to get free restores to help them move these older vehicles, and at the same time you can deduct your normal restore fees as a charitable donation on your taxes.

If you made it all the way to this point, congradulations.

Bottom line, research and proctice. Keep in mind that each satisfied customer becomes your unpaid salesman and many of your new customers will be referrals.You can mix and match. Buy your coating here, your stripper there, sandpaper somewhere else. And when buying coatings, you will have to buy a minimum amount. Many coatings have a limited shelf life, so starting out you might want to start with a 2K water based product that has at least a one year shelflife.

Avoid any coating that is not clear. These dark wipe on coatings will only get darker with age.
 
The biggest problem using Opticoat (or any other coating without any documented history) is if you're charging customers, how long will it last? Will the customer be coming back to you in 6 months?

There are coatings available (although not retail) that are for headlight restoration only that do last.

The actual cost for the coating is something less than a dollar per headlight. Why chance it? Also, with a good coating you can give your customers a written guarantee.

without any documented history? OPT has done extensive testing with their various single component resin coatings for years, including industry standard testing like CASS, modded filiform corrosion, climatic extremes and various ISO/DIN tests. it's a permanent coating that only gets harder with time, however its durability is tightly correlated to certain substrate preparation and, in my uninvited opinion, needs to be layered within the initial cure time to get somewhere over 1 micron build thickness (Opti-Guard is slightly different and therefore yields different results). single applications can vary according to technique and often times do not offer the ideal build thickness necessary to provide the permanent protection that is otherwise possible with 2.0. but the product can do it and do it well - you just need to know what you are doing with it.

i can't speak about the restoration done on the Grand Marquis because i wasn't there to execute it in the way in which i have found it to perform best.

I'm sure OptiCoat is a great product, but it seems like it produces a very thin coating. In general, UV protection coat lifetime is related to the amount of UV adsorbers. The more absorbers, the more UV it can keep from damaging the polycarbonate. At some point, all UV absorbing materials will fail, it's a question of when.

Sealing polycarbonate is needed to keep moisture away from the polycarbonate, but most any product will do that. My concern is UV protection.

If Opticoat has been tested specifically as a UV absorption coating over polycarbonate, then I was wrong.

I'm just saying that if you are charging your customer 40-120 for restoration, you better feel comfortable about it's lifetime. If you are, you should give your customer a written guarantee.

Hey Ray, quick question. Are acrylic turn signal and tail light lenses UV coated like the polycarbonate headlights or are they bare since acrylic is more robust in terms of UV robustness?

As was explained to me by a chemist, acrylic can develop a scum on the surface (milky) due to solvents evaporating from the acrylic, but he couldn't explain for sure if they're coated or not.

In practice, the same coatings that work for headlights work for acrylic as well, even though the UV adsorption properties are probably not needed.

Acrylic is very easy to repair, and rarely needs sanding, only stripping and re-coating. In 4 years have never seen restored acrylic deteriorate.

A quick idea for those considering this approach for the first time ---

I went to get supplies today and found a few items that will get me started without much expense.

1. Prices at Wallyworld much better than Lowes for simple green and min wax.
2. 3M has some variety packs of sandpaper -- sheets that can be used wet for hand sanding. One pack had a variety of gritty first pass sheets -- from 200 to 1000 grit. A second pack had the fine grits with one sheet each of 1000 to 2500 grit. $5.99 at Autozone for each pack. Both wet and dry sandable.

So, this gets me started without a bunch of $$$ out for one personal car job coming up.

Thanks for all or your wisdom in this thread...I'll let you know how it turns out!!!
