With the conversation on rust encapsulating paint going on

My question is: What paint should be used on the insides of sills?
I am in the middle of replacing inner and outer sills and floors on my 4A. I am repalacing most of the inner sill, with a cutout around the a-post, and replacing the bottom half of the outer sill (there is only surface rust at the top, and this way I get to keep the original sharp crease in the factory sill). I am also replacing the floor. Order of work is inner sill, outer sill, floor.
Before I put in the floor, how should I protect the cavity inside the sill? It is a mixture of surface rust and the paint used on Heritage replacement panels. I sprayed Rustoleum rust converter on the cleaned up remnant of the outer sill, and was going to topcoat it with a color coat of Rustoleum. Once I am completed with the car, I'll inject Waxoyl (spelling?).
Is a POR-15 type of paint better? I figure this area needs to be coated and protected as water will enter. But it will not see the light of day nor any stone chips.
