StoveboltSteve -
I needed "bowtie" blue for the bowties on the hubcaps of my '54 3104 truck. I contacted the GM Heritage center for info on paint colors and they gave me the mix number. I bought the paint at a PPG store. I masked the bowtie with 1/4 inch #06405 3M 471+ Vinyl Tape and used an airbrush to shoot the paint. I didn't scuff the chrome before painting. It's holding up well. Don't know if the color that the Heritage Center gave me for my '54 truck is the same as the bowtie on your passenger car. Here is my recent VCCA post on the color, technique, and results.
> '54 Hubcap Bowtie Blue1-Shot "158-L Dark Blue" seems close to the PPG blue that the GM Heritage Ctr specified for my hub caps. That's the brand and color that Chevs of the 40s sells for painting emblems. You can probably buy locally for about the same price. You can apply it with a good brush. It flows out smooth. Sticks well to glass (and chrome). It dries slowly, so watch out for dust nibs. You will probably be able to wipe off any paint that ends up in the wrong place on the emblem before it dries. ("158-L Dark Blue" is not the same color of 1Shot that I showed in my VCCA post. "Reflex Blue" shown in the post is lighter than "158-L Dark Blue.")
> Chevs of the 40s blueFYI - The red paint for emblems that Chevs of the 40s sells is 1-Shot "104L Bright Red". You can't see the name in the photo, but the UPC code confirms the color. 1-Shot has a vermillion red paint "100-L Vermillion", but it looks too orange to me.
> Chevs of the 40s redIf you want to use vinyl, stop by a couple of local vinyl sign shops to find the best shade of blue. Shops have various shades of colors of vinyl stock based on their needs. They may give a small cutoff to you or charge a small amount. Draw the pattern on paper, then sandwich the vinyl between the paper and a cutting base. Cut with a razor blade and straight edge.
I used black vinyl sign material from a local shop for the bowtie on the radio block out plate on my '54 3104 truck.

The bowtie on the decal pack is lighter and brighter than the paint color that the GM Heritage Center specified. You will probably need to trim the decal to fit your application.
