I bought some of this to polish my hinges.
As soon as I opened the can, I was right back in Navy boot camp, polishing the garbage can with a recruit named Frechette.
I was there, in the compartment, with the sounds and the smells, and hearing her telling me to hand her the Nevr-Dull.
It was uncanny how completely it all came back to me.
