cracked edge is no big deal... there really isnt a way to fix a cracked edge, just an edge thats pulled out entrely.... and when you fix that you use a dremmel, cut out the portion of the edge that was fucked, along with a portion of the base in that area, then you get repacement edge, cut it to fit the gap, screw it in, and base patch over the top of it. bam good as new.
