Hey Matt, I wouldn't necessarily recommend sealant on the bolts. It's my feeling sealant tends to open up enough, eventually, to allow water to seep it and then the sealant inhibits the drying out which could lead to worse free/thaw action in the hole.
Consider a short length of steel chain (five links) on each hanger, connected to the hangers with a screw link for a nice, long-lasting rap anchor.
