Had one last month like that -- one of the Pittsburgh road gons, I believe McKeesport Connecting.  Fortunately there wasn't a lot of lettering, and I may still put some reweigh data over some of the broken-up lettering.

I used the Microscale decal coating fluid on the few F&C decals I use, but I thought I'd fly without it this time.  Fortunately, it was just the capacity data that I started with.
