Greg Delhierro, of M & M Signs & Graphics, recently used Precision Board Plus for some exterior channel letters. This is a very new application! Being on a tight deadline to finish this sign, they opted to experiment with Precision Board Plus they had in stock instead of using aluminum.
The channel letters were crafted from 2 sheets of laminated Precision Board Plus PBLT-15, and backed with e-panel, which is an aluminum composite material. The Precision Board Plus was primed and then coated with Ronan Aquacote, which is a very tough paint, ideal for exterior weather conditions. The faces of the letters are clear translucent vinyl, and LED lights provide illumination.
