Coffee grounds mixed with the epoxy make a nice dark filler . It looks better shaved off than sanded. Try on test piece first. I have found sanding, even with fine grit leaves a grayish cast. Have not tried wet-sanding with 1000 grit, etc though.

Best to shave off any excess after it has set but before it fully cures (i.e, I use this for filling knot-holes, etc using Loctite 5 min epoxy. I shave off excess at the 10 to 15 minute mark, depending on temp. Slower setting epoxy will mean longer time before shaving.) A sharp card scraper works for the final couple of passes. For heavy excess, I use a sharp wide paring chisel. If you are worried about gouging the surrounding wood with the chisel, use the chisel bevel down and rock it forward until you get the right angle .

I also second the clear packing tape masking. That is what I use also, but have to cut out the hole with an exacto knife.

Go

PS: The Loctite brand may be a bit yellow instead of perfectly clear, but isn’t noticeable for my use.
