Gas Model Tissue (GM Tissue) is a modern light weight iron-on material replacing silkspan and dope on 60" or smaller models. GM Tissue is very light and strong synthetic material that is airtight, waterproof, and resistant to diesel and glow fuels. It can be painted or doped. This iron-on covering is applied after the framework is coated with a heat activated adhesive such as
or Balsalrite. Apply the adhesive, let dry then seal the covering to the edge with a modeler's iron. Proceed around the perimeter and when all four sides are sealed shrink the covering with the modeler's iron. Avoid heating the edges to prevent the covering from loosening.
It weighs .849 ozs per square yard.
