nice work, BTW, how long do you leave the stencil on between colours? Do you wait until its touch dry or fully?
Rob - I wait at least 24 hours in summer. This gives the paint time to shrink, expand and do everything else before it cures. Usually, the second stencil is applied over the fresh paint. I NEVER risk painting too soon, or I could lift the paint.
I have painted undercoat / primer and then 4 hours painted the base coat. That's no problem. The paint dries in 1 - 5 minutes. That's why you need to prepare and work fast !
