I'd have thought he's entitled to an answer if one is available – after all thats why he posted the question. Still one continues to see the kind of warm and friendly attitude, allied to useful and accurate advice that persuades me to visit but rarely.
I wouldn't worry about the oil creeping – the paint isn't going to get into places, and longer term the oil in there might do good. I'd just give it a spray of oil personally and put it aside. I've used penetrating oil on the joints for good reasons. Then come the day, give it a good scrub with a brush in hot detergent and get it warm to dry. (If you are brave enough and use gloves, then very hot caustic is pretty good, but be careful – eye protection and all that stuff) Prime and top coat ASP
Priming at this stage – depends on how long you want to keep it, but most primers are porous. So there is a limitation there.
