Coming along great. You have talent for rust repair for sure. That can be very tedious as I've found out. I second the idea of using POR 15 on the inside. We use a hand pump sprayer. Load it up and let drip. Seals everything from the back. Then throw the sprayer in the trash. Also if there is left over POR 15. set plastic wrap on the liquid before reattaching the lid. It'll keep it from hardening in the can.
