Horn Grill

Going to work on the horn grills and then restoring the original Bosch horns.  I am fortunate to have original horn grills that have the small rivets.  Rivets larger than the ones in the photos below are a real "tell" of reproduction units.  
So, 50+ years of grime to remove, and much easier to do these when they are off the car.  I soda blasted the back sides, which got them nice and clean.  No blasting on the front, just lots of washing and 3 - 4 rounds of polish with Mothers aluminum polish.  It is not advisable to try anything more harsh, as the bright anodizing will come off.
​They are not perfect, but this is another place on the car where a little "patina" is ok.

Of course, I forgot to take a "before" shot, but the bottom photo shows what I started with.  It is a shot of the horn grill and the lower grill.  The horn and lower grills (where the fog light would go) were in the same condition.  The cleanup of these is a ton of work, and unless you are afflicted with originality disease, i recommend just buying reproduction ones. Cheap and pretty.
