Someone has finally read our minds and created this product. The invention of this stencil cap means that we will no longer spend 15 minutes or more having to make one from scratch. Now you can pick up a few of these and be set for a while. Plus you will get far more consistent results with these than making your own. The stencil cap is used to create ultra thin lines by installing it onto your spray can in front of your cap’s nozzle. This stops the flow of most of the paint which dispenses from the can. The paint that makes it through the stencil cap creates lines which are far thinner than any spray cap available.
