I picked up a bottle of this (I think it was this - don't have it in front of me) at Auto Zone last weekend. They only had one bottle, right beside all the various headlight restoration products. I slathered it on my recently polished out headlights. We'll see if they stay shiney and clear longer than without the sealant.
Very interesting. I may go check out my local Autozone/Advance and see if they have this.
Raider... I used my 18v drill and it definitely made easy work of it, but you are right, once you get the polish worked into the buffer you can really smooth em out quick.
