Oratex on the trim tab

My son is a huge fan of the Luftwaffe. So when he saw Coltin Brown's OD Highlander at OSH he said that we should cover ours the same and add German Storch markings.  Here is a test piece of Oratex on the trim tab.  As Paul "BDA" on the Wings forum states, there IS a learning curve.  I'll re- do this later when we initiate the covering process.
