Nasty Stencil Gel is 100% hypoallergenic
Shave and prep skin
Apply a thin layer of gel to the skin. More is less. If you use too much the stencil lines will blow out. We suggest testing first to find the sweet spot on how much to use.
Let the gel flash off for 20-30 seconds before applying stencil.
Let stencil dry for 10 min before starting
