The West System is from Bay City, Michigan.  It is manufactured by the
Gougeon Brothers, who developed it for their boatbuilding business.  I
have not tried it yet for wood repair, but I have talked to at least one
contractor in mid-Michigan who has used it as the alternative to
Abatron.  It was also used for restoration at Wingspread, discussed in
an amazing presentation at last year's APT conference in Chicago.  I
noticed that it is now available in our local hardware store in Ann
Arbor, so maybe its use is spreading.  It is still an epoxy system, and
not acrylic.
