i have the one that wipes off and ended up spraying it with hair spray.
i also was using a stencil with connecting leaves and trying to wipe the pad across the stencil kept catching on the tiny sharp areas of the leaf design.
the chaulk is meant to be used with continous design stencils so perhaps it can be wiped across on those. i ended up "pouncing" it to get my design on the border.
