    Headlight Restoration-new UV sealant idea

    I bought mine straight through Griot's and ended up returning it and exchanging it for Griot's 6" orbital, since I do some detailing work as well. I am pretty certain that you can return the machine for a refund though. Ask them before buying it would be best. I ran into a lot of lights that had...

    Headlight Restoration-new UV sealant idea

    I know you asked Louie these questions but I will add my two cents if thats ok. I bought the Griot's 3" orbital. Their instructions say to dry sand with most of the grits. I used it like they said and found that the discs do in fact clog up quite often and must be cleaned by wiping with a dry...

    Headlight sealant: spar urethane vs. opti coat 2.0

    I'm sorry but I have no idea if those numbers belong to the right or wrong type. I looked all over my current can and find no such numbers. Maybe someone else can help.....?

    Headlight Restoration-new UV sealant idea

    I use a Wendy's Frosty spoon and only mix exactly what I need when I need it. A while back I tried mixing some in a small glass jelly jar with an air tight lid. Within about a week it started turning darker colored and when I tried to apply it to a headlight.......lets just say the results were...

    Headlight Restoration-new UV sealant idea

    Are you absolutely sure that you are using the correct Spar? They make a few different types of finishes. The one you need to use is the Minwax Indoor/outdoor Helmsman Spar Urethane "CLEAR GLOSS". It comes in a 32oz can with a green label. It almost looks like you may have not got the "clear...

    Headlight Restoration-new UV sealant idea

    It almost looks like you didn't sand all of the old coating off. The second picture looks like there are small pieces on the lens or something. Usually when you wipe the completely sanded lens with mineral spirits, you'll see about what the lens will look like with spar on it. If it isn't clear...

    Headlight sealant: spar urethane vs. opti coat 2.0

    I actually use a wendy's frosty spoon and mix mine seperately per car at the time of application. I tried mixing it before hand and storing the mixture, but it seemed to turn a darker color as it sits.

    Headlight sealant: spar urethane vs. opti coat 2.0

    Thanks Hotrod. I've followed this and other threads for some time now. I've been restoring headlight lenses(mostly for a used car dealer I know) for over 1 1/2 years now and held true to the spar method. The only things that I do differently are that I sand everything by hand now, except for the...

    Headlight Restoration-new UV sealant idea

    Its kind of hard to explain as to when you need to switch paper grits. The more you do them, you get a "feel" for how its supposed to "look". I know that isn't much help but I guess your looking for the lens to have even smooth sanding marks. I use a hose to rinse the lens and paper often, plus...

    Headlight restoration 50/50.

    Yeah, it seems that they package things differently in different parts of the country. Here in Daytona Beach, Florida they sell a 30oz plastic bottle of Kleen Strip Odorless Mineral Spirits. I can't remember the price. I was thinking it was like seven something...?

    Headlight Restoration-new UV sealant idea

    Judging by your pictures, I don't think you even need to use the 400. Start with 800 and work your way up the way you stated. I wouldn't use the Laminex either. I use the spar/Min spirits at 60/40 myself. Also, don't remove the lenses! Way too much work. Just use blue painter's tape around the...

    Headlight restoration 50/50.

    The stuff I get comes in 30oz bottles at Home Depot or Walmart for like 8 bucks......does 30oz last you 3 years or don't they carry the 30oz bottle where you are?

    Headlight sealant: spar urethane vs. opti coat 2.0

    THAT is the ultimate question!.....lol Some people feel that it does and some feel it doesn't. That would make for a great test of time!!! Leave the one sanded to 800 and the other one sanded to 2000 and lets see how they wear. Keep us informed? I've always thought it did make a difference...

    Headlight sealant: spar urethane vs. opti coat 2.0

    I think sanding with 400 is good but I recommend at least sanding with 800 and 1500 before applying your coating for a more clear look. I just finished a Plymouth van using 800, 1000, 1500, 3000 and then the Spar method and they look like new.

    The reason most of us use the can over the aerosol is because you get way more product from the can for the price.

    Headlight Restoration-new UV sealant idea

    I'm wondering if you are actually seeing cracks in the lens itself. Some lenses have small cracks that can never be removed. I've run across this before. If thats the case, there's nothing you can do.

    Headlight Restoration-new UV sealant idea

    I'm not sure why you'd get bubbles. Maybe try posting your entire process with every tiny detail. That way maybe some ideas will surface. I wet sand everything with 3 or 4 grits by hand.....then clean well.....wipe with the mineral spirits and apply the coating mixture. I sometimes have some...

    Headlight Restoration-new UV sealant idea

    I used the 50/50 mixture over a year and had some where the coating seemed to wear off somehow. I began using the 60/40 and haven't had any problems since. As far as the question about bubbles....... 1. Do you shake the mixture up in your bottle? I use a small cup and mix lightly with a plastic...

    Headlight sealant: spar urethane vs. opti coat 2.0

    If I recall correctly, someone did try the opti-cote with a non-polished lense and said that every little sanding mark showed up and it looked very bad. (not positive)
