NOW to keep the lights looking like new for a long time, spray them with

Thanks for that suggestion as this is the first suggestion, I think, for an
automotive "2-part clear" as the protective coating.

Searching, is this what you mean?

This is how I deal with the yellowed/cruddy ones. They yellow due to the
UV from the sun, it kills the protective coating on the plastic.

Does the irony of that statement ring true for you as it does for me?

The 2
part clear when you're done will restore that plus it will seal the plastic.
I use bulk supplies but the 3M kit includes enough to do a couple sets
of lights and it's good stuff. DON'T use a high speed drill with it, you
can burn the surface of the light.

A lot of people are voting for the 3M kit components.
Fewer for Sylvania and Blue Magic.

The 3M kit works very well. NONE of the chemical only kit's work. I've
done hundreds of headlights using the sand, polish, clear coat method.

The UV, age and other chemicals just destroy the lights. The plastics
have gotten better but some brands just seem to turn to crap faster.

is a true 2 part clear in a spray can, if you don't have a spray gun.

or if you have a spray gun and know how to use it

would work as well.
