So most boards I ride I never bother with small bottom dent repairs (unbroken glass). But I have one board that I would like to keep as pristine as possible. I dented the bottom of this board with my knuckle. So I am interested in what combo or resin or resin and filler will result in the most invisible repair athletically? Just resin? Or too much shadow? Milled glass? Sugar? Qcel? Weight not an issue, just want to restire it as cleanly as possible.
