I use their selection of tapes due to the thin width options available. I just can't cut 0.7 or 0.4mm by hand with a straight edge. Bleeding is minimal if at all, depends on the surface and the surface prep; I've had really good results on brass models and enamels from a spray can, never mind having more control using an airbrush, so I think that's pretty good.My only advice, keep this stuff stored in a dust free container and don't let it touch your clothes, work top or anything when working with it as it attracts dust like crazy. Nothing worse than laying two parallel lines close together and then seeing that tiny spec of dust at the edge.
