A better alternative to using spray paint or markers to hide those ugly white letters on Umarex air pistols
Just make sure to scrub the area with an old toothbrush with rubbing alcohol or solvent de greaser. Apply with a Q tip and watch it darken to an almost black, like 90%
If the pistol is made of an aluminum alloy, then I tend to use this in combination with Suber BLUE from Birtchwood ,
