    ...I think you are correct sir...when I got the car the passenger side lens was hanging on by the rubber trim...so I pulled it all the way off...cleaned it up and reattached it with silicone...then when checking the drivers side I noticed the scalling on the inside of the lens...tried to pull that one off and it would appear that someone has already glued it back on...so I think I'm 'stuck' so to speak with replacement...

    Re: Yellowing headlights

    That is EXACTLY what I did. Before you spend money on a replacement, try removing the lens (you have nothing to loose). Once you get a small opening to insert a fine bladed screwdriver or knife blade, or maybe even a fine toothed, thin hacksaw blade, the rest will usually com along, much like opening an oyster or clam.

    Well I guess I got ripped off on the 3M kit so I'll return it and see what price I get @ walmart. What's weird is the 3M kit I got is part #39045 but looks like the #39008.

    Also I did see spar urethane but all I was seeing was a gallon of it in the paint cans.

    I bought this:
    http://www.rustoleum.com/product-cat...-spar-urethane
    The guy there swore by it and suggested 2 coats then sand with 220 and apply 2 more coats. If this won't do the trick I'll return it for the spar urethane and mineral spirits mix.

    Also I thought about taking the headlights off when I do this because there are no outlets where I park my car (no garage). I just have to figure out where best to prop it so it stays put.

    That spray IS a spar urethane and will work better than mixing and wiping it on. I'd have bought that if I had seen it.

    I think I paid $10 online thanks to a tip from Bass. You can surely do better than $30.

    Here's one for $13.50 with free shipping.

    Re: Yellowing headlights

    All the talk about this kit and that. There are inexpensive "household" fixes that work as well. I have used the oxy-clean paste trick myself and it brought the lenses in question back to "clear and bright" but provided no on-going UV protection. Great in a pinch but you have to do it every so often.

    Nothing short of sandpaper will remove anything but light oxidation. And nothing short of power polishing will remove the sand scratches.

    depending on the condition of the lens -
    anything short of the refinishing process described above
    is a total waste of time and effort -

    Yea basscatt that was a good tip I just watched a video on YouTube with someone doing the spar urethane and mineral spirits mix and looks great.

    Hey have you ever used or seen results with the spar urethane in a spray can such as the one I posted?

    Also now that we know the process to restore headlights I guess the most important tip is how to maintain them.

    So what's your suggestions guys? Wax the lens every so often with a compound?
    Then eventually when the sun eats away at the uv protectant buff it out with a compound and simply apply the uv protectant again?
