ive been asked to supply some signs for a hospital. they are very particular about what they want.
the graphics & materials are not a problem but they want the sign fitted on posts use channel & clips. the catch is, they do not want rivetts used for fixing the channel to the sign blank. nor do they want any fixings that can be seen from the front of sign.
ive heard of an adhesive or tape for this has anyone used it before or know of it?
