Just had my plane done by Jim Cutshall of Wing in [Virginia. Jim made his way up in the fog this morning and worked all day on my plane (as well as one other based at BWI). He did a fine job for a very fair price.
They deoxidize the plane then treat the plane with a Teflon sealant as well as clean the interior and windows. One warning…Teflon is VERY, VERY slippery. If you were to find yourself wandering off the wing walk area, you might find yourself on the floor of your hangar in about 1.8 seconds. You won’t know what hit you. Could make for a very embarrassing incident! [;)]
