I did it with plasti dip last night. It was kind of a trial run to see how it would work.
Every coat (I think I did 6 or 7) I did, I'd wipe the chrome off before it dried. I used q-tips or my finger and it worked pretty well. The raised chrome border helped you keep the q-tip on it and not the inner part of the letters.
It's a bit rough but I think I could get it smoother next time. Even now, I think I could get some of the little rough spots off.
The lighting in my basement isn't the greatest, but the chrome really does shine.
