Thanks Carl, on the idea for the bottom of the seat its just to cover the glue and material on the very bottom, for sure hard to see but if any one was to look under it just wanted to cover up some of the adhesive used to glue the material down. When they judge for our quarterly contest we have a member that brings in a large mirror and a clear shelve that we place the models on and there may be a chance at that angle to see the rough area.
