Gave this a shot of my repro orange bar crest.
I like the outcome.
Now I dont need to worry about my original orange bar crest being stolen when I park it.
You will note that the enamel stained a bit and began to slightly chip where it met the brass.
While not an exact replication of the natural oxidation/aging process, it works IMO.
On my aged "preservation" '68 912 - it looks right at home.
The "bling" of the new crest was just a bit too much on my old car.
