I've fretted my board(ebony) and filed the end of the frets flush. I need to fill the open slot ends. What's the best way to go- black CA or CA and ebony dust? Also could someone give me a brief run down of the procedure for using CA and wood dust to fill the slot ends?

Also while I'm thinking of it... I have to glue a strip of wood on top of the truss rod so it will sit flush in the neck channel. Is it ok to use spruce and glue it with CA glue? I know some have used maple but I don't know if it matters.

I use acrylic paint to fill the end slots. I put the paint in a serynge and use a very fine needle. I let the paint dry overnight and sand the next day. The fun part is that I get to my colors (I usually use rosewood fretboards)...

Jeremy, I just did this last night for a Cocobolo fretboard. I sanded the edges with fine sandpaper (I used 320) or so and thus filled the slots under the frets with fine dust. Then I drop in a tiny amount of thin CA into each slot. Wipe off excess and repeat until the slots are all filled. Might take 3 times or so. What is nice about this is the fill material typically matches the board very nicely and the slots are invisible.

Thanks guys I'll probably try the dust and thin CA technique later today.

I just finished and you were right, the slots are nearly invisible. Thanks again.
