I finished the relettering and put some clear semi-gloss coat over the top of it.
Lesson learned: black sharpie (which I used for touch up around the lettering) may run when hit with a top coat. The black sharpie ran down over the lettering and I was devastated. My wife suggested using a gold sharpie to fix it. And guess what? It worked! I'm happy to have my lettering back and not have to start all over again.
And here is its new boiler plate.
