A gooseneck cabinet scraper (the bottom of the 3 in the pic) should work for this, either store-bought or built out of a hacksaw blade or other steel remnant. An ordinary paint scraper will clean up the edges OK, but won't do a very good job on the bead itself. The beauty of the scraper is that you can use it while the epoxy is still green and easy to cut. If you try to sand it at that stage of cure, it just makes a mess and gums up the paper.

Next time, lay down duct tape 1/4" away from the joint on both the horizontal and vertical, tool the putty so it feathers at the edge of the tape, and pull the tape either right away or when the epoxy starts to gel.

: Hi Folks.

: I did the sealer coat last night, and then applied the fillet this morning.
: Things didn't go so well with the fillet -- it was a messier proposition
: than I'd anticipated. I think I've got some remnants to clean up from the
: fillet and I'm wondering the best way to go about that. I think the fillet
: itself is fine, but it was a bit sloppy. Any ideas on how to clean up the
: mess? The below photo is the best for seeing what's up, the rest turned
: out a bit dark. But you can follow the link to see the balance.

: I'm guessing I'll have to wait for awhile, let things stiffen up, and sand
: the leftover fillet material away. I'd like to hear differently, but I'm
: guessing that's the way to go. Anyone have advice?

: Thanks again for y'alls help.
