LiquidWood
LiquidWood is an epoxy consolidant which essentially means it is a low viscosity liquid (kind of like syrup) that is combined 1:1 (meaning you mix half part A and half part B). Its thin consistency allows it to penetrate deep into the wood and strengthen rotted wood back to where it should be.
WoodEpox
WoodEpox is a two-part system like LiquidWood except that it is a paste filler instead of a liquid. Parts A & B are mixed together (in equal portions again) and they can be molded, troweled, filled into any void or portion of wood you need repaired. Once mixed together the paste has a play-doh like consistency that is easy to work with.
