Spray preservative for backs/bottoms of seats ?

[Racer57]

My back seat is in perfect condition until you look at the back side. Its very dry and falling apart a little, but not enough to replace considering its hardly used. Is there anything that could be sprayed on it that would maybe put some moisture on it and also seal ?

I hosed my original 73 foam backs and undersides with a full two cans of cheap home depot flat black rattle cans.

Not only did it seal up the crusty foam and preserve the listing wires for another 40+, it also eliminated the extremely nasty "old mopar" smell......
