Over " N " Over Stencils instruction
Specially developed for the Armour sand blasting system but also easy to use with Armour Etch cream. Each stencil can be reused between 15-20 times depending on the amount of sand blasting pressure, care of use, distance between the tip of the blasting gun and the stencil, and the type of abrasive (we recommend between 180-220 grit size preferably 220).
