The kits are a group of existing products repackaged and marketed for this purpose. You don't need the kit to get them.
 
You can just use sandpaper or any polish depending on how bad they are to start off with.I did mine the other day i have a 3 inch air buffer but you can buy a backing made for a drill.
 
I have a hard time using abrasives at all. A headlight lens is made of acrylic or Polycarbonate. Polycarbonate and acrylic is susceptible to UV and oxidation damage. To protect against that they are usually covered with a UV oxidation resistant coating. Sanding the top layer would remove that, making it degrade faster in the future. I suppose that may not matter because its a mess anyways, but I still try to use an off shelf anti-oxidant cleaner and a less abrasive buffing compound first to see what happens.
 
yes, and dint these lense having a coat of protection, after sanding it off nnd cleaning its good idea to spray a clear coat over it ?

The toothpaste trick came from the days of the glass lens. If he took care to prevent scratching the lens using an orbital I suppose its still ok.

I have done that. The clear can resolve fine scratches and imperfections that impact light refraction. But it does not necessarily provide UV protection so the problem can resurface, this time under a coat of clear. The kits contain a polish that needs to be reapplied, maybe thats a better idea.
 
I have been using Plast-X from Meguiars for years now. I use it maybe twice a year with my DA buffer and my lenses look brand new. Clear as can be.

It's that UV coating that deteriorates and caused most of the problem, should be outlawed... Most park lamp lenses do not have such coatings and hold up far longer than headlamps...

Above said, if you use a good paste wax three or for times a year, the UV coating will generally not deteriorate and get hazy...
 
I don't think 3m or any of the lens restoration kits is suggesting that sanding is the right thing to do. I think its more of a last resort before replacement. In that case, orbital sanding is key, not wet sand paper on a block that will leave scratches that impact refraction.
 
Over all it still better then those that sell on tv, put on wipe off " type. I fall for that once

never again. But use buffer help alot.
