Your story about using the gonicoll and having a prolem reminded me of the
time my dad, who was a traveling salesman, demonstrated a supposedly
unbreakable flashlight to a group of possible buyers by throwing it across
a hotel room. You guessed it...it broke into a multitude of pieces. Is
gonicoll good for hanging posters on painted walls that don't have too
many layers of paint? We don't get repainted that often.
