Mine is not a Europa but similar problems.
I anodised most aluminium parts. I allodined most of the ones I didn't or
couldn't anodise. Allodine is not a robust finish so I painted or varnished
the allodined parts as well. Most steel parts on my kit were plated, powder
coated or primed. Priming does not generally protect against corrosion. I
think most primers are porous. For some parts I used steel wheel available
for painting car wheels. Its inexpensive, quite robust and easy for small
parts that would no justify getting out two pack paints. I also used aerosol
zinc chromate for small parts. Etch primer and epoxy primer and two pack
polyurethane with UV blocker. Both Allodine and zinc chromate contain chrome
and may not be nice materials.
That's what I have done which may or may not be a good idea.
