Yes, there is some sort of oxide type coating on them. Odd thing is that it seems to add no resistance when I tried measuring them with an ohmmeter. I get about 0 ohm on ones with intact coating vs ones where it's come off.

Here it is all back together. I had no trouble fitting all the pieces back in. I smeared some T9 on the plates which I figure will inhibit rust and add a little insulation. Still waiting for some fresh paint on the frame to dry before I try it out.

I'm also finally getting around to restuffing the copper caps. I'm using three 2.2uF film caps in parallel to get around the original value of 6 uF. The end is sealed with black hot glue so they're easy to reopen if ever necessary.
