no problem.....since no one is giving up their technique, I'll let you know what I found out.
I tried to wipe of the excess at varying stages of curing.
I found that with the enamel model paint that if you let it dry at least an hour before trying to remove the excess, the fill looks much better and stays in place longer though the excess removal process.
If you let it dry overnight it seems to be even better as far as the finished look.
