It is not supposed to be a thin layer, it is a bead layed down out of a caulking gun, ~4mm in diameter per the FSM. It is not a cheap solution, it is actually more expensive as it requires more exact assembly practices as we have experienced the shoddy end of.
There are a few reasons to use sealant over gaskets. On something like the timing cover, a gasket wouldn't work and would leak all the time. That is a big cover and when you throw in the stresses on it(the oil pump is housed in the cover), and heating and cooling cycles it just doesn't work. Another is the tolerancing on sealant is more consistent over gaskets. You also get firmer fastening between two parts.
