A rag with rubbing alcohol was used to wipe the surface, if done carefully the repair could be leveled with the finish and no refinish would be required.
Now, that sounds like a good idea.
Brownell makes an Acraglas solvent that I like. It cuts the epoxy and is good for cleaning up.
I'll have to try the alcohol trick.
The Gel is sorta thick, but with a gap cut thru the crack, it does go in with a wire/paper clip. Its consistency really fills the crack. I've used the std. and the Gel, prefer the Gel.
If someone was going to try to wedge the crack a bit, the std. product would probably be better. Those cracks aren't that easy to wedge open, IME. The drilled out gap assures good coverage of the material and the Gel doesn't need wood to wood contact.
