I merged the two 41-616 electronics/chassis threads to keep the topic together.

I've only fully painted one chassis and it was pretty badly rusted.  I just rinsed the naval jelly area well, wiping with wet paper towel a number of times.  Then I primed entire chassis with rusty surface primer and followed with aluminum (i think) colored rustoleum.  

Looked ok, not great.  On less rusted chassis i just paint the derusted area with a thin wash of paint trying to mimic the color of the original areas of the chassis.  If i can locate it, i'll add a link to my thread later today.  Remember for components that need chassis contact for ground or B- you can't paint that.

This isn't the thread i was thinking of but has a mix of things i mention above:

Naval jelly is acidic, containing phosphoric acid, sulfuric acid among other things so adding a little baking soda to your rinse water would further help neutralize the jelly as well.
