In 2003-2004 his mentor, friend and agent told him to establish a niche, as he did creating art that is very unique in the art world.
The roofing tin is an interesting material to paint on, that how the actual painting was created. Using the rusty, dark tin as the darkest part of the shadows, and the outline of the subject. At the time, he was only using scrap house paint, then transitioning to acrylic paint. Using only the minimal amount of white paint to capture the light and heavy paint for the brightest.
Back in the year 2000, Giltner was asked to participate in an art event in Columbia, S.C. At the time he couldn't afford canvas to paint on, so he utilized wood and tin from derelict tenant houses located around Chester County. After asking permission to salvage the wood and tin, he then dismantled the structures piece by piece, to create his canvasses to paint on.
