New Old kit RV 4: interior priming

Hello, I am the new proud owner of an RV 4, originally bought around 1986, more parts added in 1998. I'm still sorting all that out. SN 552.
All of the control surfaces/Empennage are built. The fusilage is on wheels but uncompleted. The wings have not been started. I will not be able to really start on it for some months.
The parts built thus far were not interior-primed or finished/protected in any way. I do not live on a salt-water coast. Do I need to worry about this, and if so, is there anything I can do about it?
My impression is that it's ok: in the absence of dissimilar metals or a particularly corrosive environment, I think of aluminum corrosion as self-limiting to a large degree. However, that is coming from a building construction point of view, not an airplane point of view.
Thanks in advance for your thoughts.

LOTS of opinions about priming...or not. Have a look around the website and/or do a search (top ribbon). Most of the opinions about not primering cite the 50-75 year old Cessnas/Pipers that were never primered and still have minimal corrosion. Most of the 'must primer' opinions lead one to believe they're building the plane to last 100 years. In my case I primered with epoxy, but I was starting with a slow build kit and I live near the coast.

Yeah, I found the many threads on priming right after I posted. I've been reading them for an hour. I'd say the finished parts will remain as they were, unprimed. I'm undecided about the wings. I think I might paint the interior of the fusilage, at least where the humans go, just to make cleaning the Cheetos out of the crevices easier.
