So I had this bright shiny German Sport Guns .22 Stg-44 lookalike. All of the real STGs I have seen at gun shows have shown signs of a lot of wear. I went over mine with Rub ‘n Buff silver, a craft item you can rub on with your fingertip. Model makers use it to simulate wear and tear on model aircraft and armor. It wipes right off with Hoppes and probably a lot of other gun cleaning products. I guess this is kind of silly but to me it makes the gun look more authentic. If you had an old gun and fitted a new part to it such as a repro antique scope sight, this would be an easy way to make it look more authentic. You can buy Rub ‘n Buff at Michaels or hobby lobby. The best stuff is in little jars, I recommend Pewter but this was done with silver packaged in a tube.[ATTACH=CONFIG]44019[/ATTACH
