Here is the result of powder coating the letters and bowtie on my AD Hood Emblem. A lot of the restoration companies sell the vinyl letter kits for these, but powder coating will last much longer and be less resistent to peeling off like the letter kits will.
I took some "artistic liberty" while doing this. I used "Transparent Blue" for the bowtie and "Wilder Red" for the letters and stripes on the sides.
This an extra one I had around the house and it doesn't have the mounting plate on the back, so it worked as a practice piece for the real one I will be using on my truck.
