FWIW, Eastwood also offers an Inner Frame Rail coating kit which admittedly would have been easier than fabbing my own sprayer, but at $20/can I thought the price a bit steep.

Now my sprayer is available for any other local Pantera owners to borrow who want to do the same thing. Might just have to have a rust-proofing tech session soon.
Either of these processes would work for coating and protecting the inside of the doors.
