Mylar stencils are extremely hardwearing and can be used numerous times. The instructons below show you how to use them 'dry' - there is no adhesive on the reverse. You can buy non-permanent stencil spray to make them tacky such as supplied by 3M but we have chosen not to use this as it is expensive compared to a stencil set!
You can spray paint with a model spray gun but you do then need to use the 3M or similar adhesive to seal the edges.
There are two sets of instructions below for a single type stencil and a multiple type stencil.
