Gorilla glue dries black on your hands but not on anything else that i know of.

: I remember seeing posted here, a glue that dries black instead of
: white/yellow. I think it is a glue that tends to foam up when applied, but
: I could be wrong about that. The reason I ask is that I am having new
: kitchen counter tops installed tomorrow (formica laminate) and they are a
: mottled black/brown/grey color, and if any glue residue would show at the
: seams between pieces, a black glue would be much less detectable than a
: yellow glue residue.
: I thank you in advance for any help you can provide.
