Is there a way to fill a narrow crack with CA without getting so much on the adjacent wood? I'm applying directly from the tube and end up with a 1/4" wide path of CA which causes the fiish to be darker if not all removed.
You can also spray the hardener on the dry wood and let it look dry before putting CA in the crack. That way it flashes on the surface without penetrating too far, but still wicks in well.
I fill (inspect, and re- fill ) early and sand late, which is safer all the way around. Much better to hold two pieces in register with glue while working them with steel. Tend not to fly apart.
