One of the small things I have going on the side, while I work on the rotisserie, is some small detail stuff. These are the galvanized steel window rails for the rear quarter windows. They never have rolled up and down too good, so I took some sandpaper and smoothed out the rails. I then cleaned them thoroughly, and coated them with POR-15. They look much better than they ever did, even at the factory. I am likely going to do this with as much of the interior window hardware as I can.
