I'm cutting out lots of rusty old bits of sill. Most of the holes were where water could sit in the base of the sill, so I'm replacing that metal (and what I had to cut off to get to it) with nice new repair panels.
I now have some minor access to interior sections of the car, and parts of the sills I've cut into. There's a bunch of surface rust, some pitting, but I don't think it's bad enough to cut out and replace.
In some cases I can get in there a little with a wire brush drill but it's not going to do all that much.
Should I paint it (was planning on EM121 epoxy primer, but I don't have a sandblaster and can't get in there for sander to surface prep)? Put rust converter on it? Just ignore it, close it all up, and spray with waxoil/cavity oil?
Here's an example:
