I epoxy'd the little chip using only 2 part Loctite as the filler. It held up fine and seems to pretty damned robust. I filed it down post application and curing and I think this is going to last.
I'm pretty happy with the durability so far, even if it isn't really above average. The base continues to get gouges but consider the shit I've been riding over and the fact I've spent several days doing nothing but hiking jibs, the abuse resistance can be considered at least "adequate" or "average".
