Love what you did here, but I can't really visualize what "[The wall panels] could be drilled right over our tar wall" means. Did you drill holes INTO the tar? That could cause the roof to leak and lead to all kinds of other problems, like mold, flooding, and a huge headache for whoever lives right below (and possibly even further down than that, if it's a multi-story building).
