    Collinite wax eh? I'll definitely read up on it.
    are you listening?

    I think if you calculate the volume that 7 ounces takes up and then calculate how much surface you can get with a thin layer, you will find you can do a reasonable number of headlights. Why not just offer it as an added protection at a higher cost. If people want the best, they need to pay for it..... and buy the bloody right light... :-) ... reputation is everything .... and time is money. The time you WASTE looking for an alternative could be spent on customers.

    If I were to decide to use this product in my business it would be at a higher cost. As of now I give my customers a 1.5 ounce bottle of Klasse All In One to wipe on the lights every 6 months. This should be fine. When my business gets in the green I will consider adding more products like clear plastic films, UV clear-coats and possibly even tinting lights (fronts or rears). I will definitely keep you all posted when I do this. And I will most certainly just buy the light offered by SolaRay when I buy the spray-on UV protection.

    Another thing to consider though is overspray from the clearcoat--that stuff can really be nasty and the products required to cover up the car and surrounding areas are both expensive and time-consuming.

    If you get a chance go to the 2010 SEMA show you'll find dozens of manufacture from chine selling the product you’re looking for. At my friend shop the simply spray the headlight with PPG 2021 clear after sanding it, or the mix a bit of black in the clear to make smoked lights. 2021 clear is considered one of the best automotive clears.

    Thank you Glock! I will read up on PPG 2021. I don't see any threads on Autopia about this product so I wonder if people on there even know about it.

    Seeing as how I have been on CPF for 5 years, I know better than to spend $220.00 on a "special UV curing light". However, I don't know where to find the right supplies for a light of this application for cheap, or what supplies I need to buy.

    Anybody happen to know where I can find these supplies? Thanks!
    The light I believe they're using is actuallya lamp for raising lizards!. They do produce UV, but lots of o0ther light too. These bulbs are expensive, about 45-60 each and do not last very long.

    It's an interesting topic becausemy company (Brite Lites) is developing a
    UV lamp product for use with some of our headlight restoration products. We have not launched yet, so don,t look for us. As far as the UV light, you need to know two things about the coating you will use.
    1) What wavelength does it need (most likely UV-A at about 350 to 390 nanometers.
    2) What dosage. This should be stated in watt-seconds or joules. It does get complicated.

    There is a minimum dosage required, but you can't over cure. After evaluating and measuring UV output from many manufacturers, we are going with 100 watt CFL UV=A bulbs. These bulbs are quite large, but product almost 20 watts of UV-A and cost about 35-40 ea and have a lifetime of 800 hours. The lizard bulb I metioned will probably require a few minutes to heat up.

    There's nothing wrong with simply exposing to sunlight when you can. If your coating will cure in 2 minutes under the lizard lamp (150 watts) it willl most ceertainly cure in sunlight in 5. What they,re probably not telling you is that you will have to move the lamp around to cover it all and that would probably take more than 5 minutes.
    Hope this helps.

    even though the thread is old, good point on the lizard lights

    http://www.exo-terra.com/en/products...cent_bulbs.php

    the repti-glo 10.0 puts out a bunch of broadband UVA and B. A sheetmetal reflector, and some edison base sockets would be a good start on a headlamp curing fixture. (or even use one of theirs, maybe with modifications if needed)


    The 2.0's are what I use in my snake cage, and they definitely give a good daylight color. They are pricy since they are specialized, but nothing too horrible.

Most cheap UV fluorescent bulbs produce less than .2 mwatts/cm2 as compared to sunlight at 6 mwatts (30 times more), so if a cure would take 5 min. under sunlight (common) it would take hours under common UV fluorescents.

    There are porfessionally developed headlight coating products that cure by chemical reaction instead of UV. Expensive to buy, but per headlight costs are 50 to 80 cents. Cures in 5 minutes and no masking required. We warrant our restorations for 2 years.

    Hi ray6,

    I realize this is an old thread, but was wondering if you're still in the headlight restoration business? I'm considering starting business in FL and would love to hear what you have learned.

    Would really appreciate if we could PM about this further.

    Best regards,
    Andrew

I also offer my customers a 3 OZ. bottle (good for 3 years or more) of said acrylic for self application every 6 months for $5.00. It's easy to put on and you just wait 15 minutes then buff it out.
    I wonder why this is all so difficult to track down, and have been looking for the same kinds of answers that you are looking for. There seems to be a shroud of secrecy around the lens cleaning industry, and it has to do with how to protect the lenses after they have been polished or restored. Like you, I think the answer is ultimately in replacing the original hardened coat over the polished lens. However none of the products I've seen seem to do that. Even thes that require UV for hardening, don't seem to meet the same standard that the original OEM had.

    Maybe just doing what you are doing is the best that we can expect. I thought about going to the guys who train people to restore lenses, but they are so secretive that it is difficult to even get good reviews of either their processes or of their products. Waxing or coating with ceramic or with sealant might be okay for someone who is DIY, but for a professional, it just seems too short-termed a solution to truly be viable.

    The UV Lamp might do the trick, but you'd still need a stand. https://viruslights.com/products/36-...IaAkinEALw_wcB the other problem would still be how to apply without dripping or streaking and how many coats would actually be adequate.

    For those of you who suggest sunlight, of course, you are right, it would and does work, however, One can hardly ask their client to wait a day before driving while the coating hardens, especially if it needs two or three coats. Also, giving an unhardened product back to the customer is asking for trouble. Both the person who restores the headlights and the person who pays for the service want to see the completed job and, as it were, sign off on it at the same time.

    If you find a good answer, make a response so as to let me know. Thank you, B. an awed1

    Talk about some serious necro-posting. I’d also like to point out that after removing surface of headlights through sanding, you MUST apply a few coats of 2k clear coat with UV additives or the plastic will rapidly degrade. 2k clear coat can be purchased ina spray can and it’s made by SprayMax. No need for fancy lights since 2k clear is a 2-part coating that is dry to the touch in minutes and can be buffed in under an hour. This process can be sped up by using a shortwave Infrared curing lamp. By using one you can buff them in in minutes after spraying.

    also, Paint sealants and waxes ARE NOT a substitute for a proper 2k clear coat. Those are only to be used AFTER clear coat is applied. The OP is essentially ruining peoples headlights and I guarantee anyone who paid to have their headlights done without a clear coat not be happy.

    A shortwave infrared curing lamp? Are you referring to something in the near-IR range of 780-900nm? As opposed to longwave-IR which we perceive as heat.
