The car is waxed and shining.

I was just wondering how much it would cost to have my car washed and waxed.

My better half screwed me over for being waxed.

The tip of the piston has a small indentation or hole, and just behind the tip is usually a gasket of some kind to ensure an airtight seal—perhaps a rubber O-ring or simply some waxed string.
