I'm working on a restoration and the plan is to ride the board once I'm finished. I'm sanding down the bottom and will be glassing a layer of 4oz to make it water tight. Of course all of the dings will be fixed before the glass goes on but I also have a few pressure dings that haven't crushed any glass, they are simply small dents in the glass. Every board in the world has these and I usually don't worry about them on my boards but since I'm going through the work of reglassing the entire bottom, I figured it would be nice to have a perfectly smooth bottom. If there's no good solution, that's fine, I'll leave them be and ride the thing anyway. But, is there a way to fix/fill these up? Thanks in advance.
