I have an old road case that I am fixing up to be my new comm box. (radio compartments, charger rail, power system, and mic compartment) It's an old case(Production Arts) that is in good physical condition but less than stellar cosmetic condition. I am going to paint the wood and polish the metal along with adding a high density foam lining. My concern is that there are a few large dents in the outside panel, which look awful. Being more of an electrician than a carpenter I am stumped as to the best way to fill the holes.
