Hi Stephen:

I've worked for hours to remove the oxidation on my SEC air cleaner 
housing using a rubbing compound and a lot of elbow grease.  Then 
applied several light coats and 1 heavy coat of clear engine enamel.  
Spray some Mop N Glow wax on the engine in general every 6 months or so 
and it'll look shiny and clean.  Both efforts seem to work although if 
you've missed any aluminum ox after spraying a clear coat it will 
reappear in a year or so.  For this reason I chose to do the valve 
covers differently.

On the cylinder head covers (valve covers) I just had them powder coated 
($40-50 for the set) and I apply a wax coat every now and again and 
forgetaboutem.  It's that air cleaner I bet that looks really nasty.  
Powder coat it or do the elbow grease routine with rubbing compound.

That's about all I can suggest.
