RE: Teak Filler
A couple of ideas..... A method recently outlined on the GB owners forum is (assuming bare wood) to first saturate the crack with CPES. Then make a thin teak wedge that will fill the crack for its length and install it with slow-cure epoxy. When everything has cured, sand the wedge down fair and finish the whole piece.
If the crack is too narrow for the wedge method, you can mix teak "dust" from filing a piece of teak with a fine file (don't use sandpaper) with epoxy to make a filler. HOWEVER..... this will most likely come out considerably darker than the surrounding wood.
Or you can experiment with some of the commercial wood fillers to see if you can find a match that will retain the correct color under whatever finish you are using.
