CB repair
Hopefully, your CB splitting is covered by warranty, try calling Hunter. They were very helpful when my CB started swelling. I wonder if yours has the same problem. I guess a certain number of CB's were manufactured with a material which swelled when wet so any opening in the outer cover led to swells and cracks in the CB (mine had a tiny crack near the screw in the bottom of the board). Hunter mailed out a new board to me ASAP (covered by warranty) and replacing it was not too bad, just a little awkward becuase of needing to lift that weight (~70 lbs) out of the CB trunk.
