Polished the surface of the pre-prototype I had made and it is really working out well even if it isn't the exact shape for production. I am almost positive it will work out since it survived over 2 hours in a 170F brine without showing surface rust - Ordered a set for my 23 to verify that the metal polishing/cleaning/passivating sequence will work right but I have to wait a couple of weeks for delivery. Got frustrated with work crap so I threw this together...
Now that I have 20, 21, 23, 27 emblem files I guess I need to think about completing the set; 18, 19, 25?.
