re size that sucker to 680x480. It'll make viewing it a bit easier on the eyes. Some stuff can be done to it. If it can't be hammered out the edge would have to be removed and replaced. Not sure if you need that at all. Does this dent affect the riding performance of the board? It almost looks like it's something you could leave alone. Along with the close up, a panned out view of the edge would be nice to see the overall impact of this. Definitely something you can take into a repair shop and see what they say. It probably won't be a cheap fix.
