Since the fuselage stringers are aluminum, I'm curious if you painted yours? I think most people don't paint their spars, or door frames prior to covering. So why paint the stringers? Thanks

I primed all those surfaces you mentioned. Its all about corrosion. The only raw aluminum my SS7 will have is the electrical trays behind the instrument panel. I don't live too far from the ocean, probably far enough to not be concerned but I will be going to the locals right on the coast as well as Catalina Island.

Like Eddie, I'll be priming most aluminium parts before covering etc. It doesn't take much more effort to do and besides that, anything you can do to help prevent potential for corrosion is, imo, worth it.

Re: Corrosion.
My Ford V6 converted to an aircraft engine was spectacular with Ford blue painted block (steel) and polished aluminum heads, manifold and accessories. Great in Pennsylvania.
One month in Florida it was horrible.
I cleaned and painted everything upon return to Penna.
My Kitfox has epoxy primer on ALL aluminum parts because I now live in Florida. I even epoxy primed the radio and transponder trays.

I also epoxy primed my aluminum stringers, spars (inside & out), and door frames. I just brushed it on; no spray mess.

I bought my plane second hand when it was about 14 years old. I don't know when the first owner painted the stringers, but there was filiform corrosion on them, under the hand brushed epoxy paint. I sanded them and repainted the stringers with epoxy primer. The first owner lived near Salt Lake City and the California coastline.
Like others have said it is about preventing corrosion.

As another data point, I also primed mine with epoxy primer.

Ok, now I know more than I ever cared to know about filiform corrosion. How can you possibly build these without learning so much. Of course you just not become a member on a forum like this. Awesome.
I did not paint my stringers. However, I did epoxy prime in and out of the spars.

Has anyone used an airbrush to shoot epoxy primer? I was thinking about giving it a try just to do the stringers.
