    I often enter slides in club competitions and sometimes I need to mask off portions of the slide.
    At present I use adhesive backed copper foil but I am sure there must be some thing better out there, can anyone help me.
    My ideal would be a very thin light proof adhesive backed material that cuts easily leaving a smooth edge.
