This is my first attempt to make a sign using Aspire. It went exceedingly well except for one error which messed up the initial lettering when it went to clear it after the initial v-carve. I am wondering if it can be repaired by using a fly-cutter to shave it down to the error. This is going in a cemetery where my father-in-law is buried and where they will eventually plant me so I don't want to put something up that doesn't pass muster. Any recommendations on how to finish it? It is made out of HDF. Thanks and I appreciate any comments you might have.
