The boss wants a sign hung above the front door.

He had a sign made at a sign shop -- 3 ft. x 6 ft. -- made from 3/8 inch
poly-something pliable plastic with vinyl (I think) lettering. In any case,
it's guaranteed for outdoor duty.

My question is regarding mounting. The simplest technique would be to simply
locate and level the sign and put Liquid Nails on the wall (tilt-up concrete
building with stucco texture) and slap on the sign and secure it while the LN
sets.

Any suggestions, observations, constructive criticism?

Thanks,
Sparky
