    It's good stuff!! I used something very similar on my Evo. Never stays perfect for too long though, those UV wipe things are a bit useless. I've seen some people put clear over them which seems to work.

    yep done this many times, however never bought a special kit for it, depending on the condition of the headlight a light sanding with fine grit sandpaper is the start. I have started with as coarse as 800 grit in some cases finished with 2000 then onto cutting compound like we would use on paint down to the finest one you can get. Then clean thoroughly as you dont want any residue left on the lense and clear coat for longest results. If you are happy to buff every 3-6 months (which is not hard to do) then the paint is not neccesary

    Yeah I get the impression that the spray on "sealant" stage 2 on this kit, is akin to a clear coat perhaps?

    yeah I imagine it would have to be something like that.

    Use Brasso from Coles or supermarket. Polish the headlights with a clean cloth and wipe off afterwards, it works perfectly, costs peanuts.
    The plastic headlights on my KQ Laser were so yellow (could not see the bulbs) 5yrs ago, after this treatment, they're totally see through like new!!!!!
    BRASSO.

    Brasso or anything else it's fine.but you must replace the uv coating when your finished cleaning or they will be yellow again in months. The goods stuff is about $60 for 100no out something ridiculous. I just paid$100 for some one to do it for me. They can do it in 1 hour, much quicker than I can and I don't have to buy any products or tools.

    ^^^^ this.

    Given I posted this topic 6 months ago, it's testament that the headlights still look great! They haven't yellowed again at all. A few new scratches of course. I'll take a pic at lunch time if I remember.

    Is your car mostly in a garage? Mine is outside all the time and lasted about 18 months with the uv coating before it started to discolour. The danger is that the uv damage is irreversible. When you clean them you are actually removing the top layer of plastic that has oxidized from the sun. If you keep doing it without replacing the protective coating they will eventually crack all over and then they are cactus.

    We're on the same page mate. ;)

    The kit COMES with the sealent/clear coat. I'm backing you up.

    That car is kept in open car port/outside and used daily, parked outside at work.

    Mine is garaged. I hit the lights with the Brasso or Silvo (depending on availability) about once every 4 mths and they stay clear as. No cracking, nothing after 5 yrs & counting. Did it on my daughters Mazda 323 as well and it too turned out great :)
    It only takes about 2 minutes/headlight for a touch up. It's nothing.

    I think Max's point is, if you're not applying the sealent, then the fading returns, so you have to re-do, which is what you've said.
    The simple unavoidable fact is, the more you "polish" the plastic, the more you are removing it's thickness over time. You are continually degrading the surface over and over without replenishing it.

    For a few minutes more, you'd only have to polish them once a year, if that, and you're not cutting into the raw material nearly as much, but the sealed clear coat layer instead.

    If you've got some acrylic clear coat around (check before use of course) the possibly you could get away with your existing technique. I'm not suggesting you "need" a $60 kit. But you SHOULD apply a protective coat.

    The only pain in the process is masking up. but that really wasn't that hard.
