Filling chrome emblems

I am getting ready to have my car repainted and I asked the guy to give me the chrome fender emblems for my 65 cuda as hes prepping the car so that I can give them a polish and refill the black paint that runs along the center of the text. Does anybody have any tips about doing this? type of paint to use? I was thinking about maybe using hobby paint with a little thinner in it with a syringe?

When I "Incorrectly" did my 69 Barracuda front fender emblems in the mid 80's.

I used some off the shelf semi-gloss black spray paint and just got the SOS pads out to clean off the excess. Pretty simple to do with some patience!

Only for me, I later learned while doing resto that 1969 Barracuda Script should be plain! It was just as easy to remove it all!

Good luck!
