    Thank you for the much needed step by step although just a FEW things are quite unclear.

    You mentioned that you use the 400, 800, 1200, 2000 and 3000 on the pads. But then you mention to use the 500, 800, 1200, 2000 sheets after each matching number pad. So am I using a 400 pad then proceeding with the continued step or was that a typo? I just want to be clear and make sure I do this right.

    Also all I have is a 18v batt drill. Any other suggestions?

    Re: Yellowing headlights

    I have used 18v drills for this. If it has an adjustable speed, set it to the fastest setting (low torque) - in most cases that would be close to 1200 rpm, which the kit calls for. They work fine. Goes through batteries though.

    Easier? Yes.
    Cheaper? No
    New headlights $200 - $300
    3M kit and a can of clear spray protectant - less that $15


    ----------

    From my experience there is no need for all the extra grits. The 3M kit provides 500, 800, 3000 and a packet of polishing compound. That seemed to do the job just fine.

    P.S.
    Kit calls for 1600 RPM.
    I used a variable speed corded drill. I think max speed was something like 2400. Even at max it seemed to be fine as long as you keep it moving.

    Re: Yellowing headlights

    Just want to chime in that I've used the 3M kit (the one made for a drill) in the past, and it works great, plus much cheaper than the others. I'm getting to the point of needing to do it to the Caddy.

    Re: Yellowing headlights

    That's gonna be a bit too large, plus you'll have no way to attach the provided disc pad.



    You could always pick up a cheap corded drill for $30 from Harbor Freight.

    It has 200-3350 RPM and the disk comes off. I need to see if they have a smaller one that attaches to fit the 3M pads. This should work though right?

    ----------

    Didn't see your post when I posted previous post. But that may be an option I go with is a corded drill from there as long as it has the right RPM. But if they have smaller pads I may be able to use my sander/polisher because the pad I have has a velcro backing to attach pads so assuming the 3M padding is velcro it would work.

    =====================
    the buffer won't do it -

    the 3M kit uses 3" discs -

    you MUST get a variable speed 3/8 drill -

    If you have a NON ORBITAL buffer, I assume you have pads and compounds?

    If so, you just need several grits of wetordry paper and you'll be all set. I use 400/600/800/1000/1500, then a heavy cutting cream, then a polish, then a swirl remover. The lenses look like glass.

    Re: Yellowing headlights

    If they are scaly and hazy on the inside, you are getting moisture in there. I have gotten the lenses off before and cleaned and resealed them.

    Well so far I got:
    3M restore kit ($30! Sheesh)
    3/8 electric drill 1500 RPM max
    water spray bottle

    I'm headed to home depot now to see if they have that spar urethane but if not any suggestions on experience of a good uv protectant? Also still not sure if I'm going to use the extra sanding methods or not basscatt suggested. The guy where I bought the 3M kit swore by this kit being good enough.

    Re: Yellowing headlights

    I'm headed to home depot now to see if they have that spar urethane
    they will have it -
    it is put out by MINWAX -
    called
    HELMSMAN
    SPAR URETHANE
    be sure you get the CLEAR GLOSS -

    don't forget the MINERAL SPIRITS -
    get the odorless type -

    and the DENATURED ALCOHOL -

    get a roll of 2" wide blue painters tape - 2" wide -

    take your time masking off the area around the headlights -
    the sanding discs WILL damage the rubber - and the paint -
    if you get a little off course -

    3M restore kit ($30! Sheesh)
    WOW - that is LIST PRICE +

    you should return it - and get it from walmart - for $15 -

    Also still not sure if I'm going to use the extra sanding methods or not
    it's just the method I found that gave ME the best results -

    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.
