I still use it...under monokote. Brush a heavy coat on bare wood and lay damp silkspan on top. Rub silkspan with fingers until polycrylic "oozes" through. While it is still wet, apply another coat to the tissue and rub it in as well. You only want enough to make sure the tissue will bond solidly to the balsa. Don't put on to much! When it dries it will have a flat look to it and should have a "fuzzy" feel. Sand the fuzz and any shiny spots, first with 180 grit sandpaper, then 320 used dry. Use a tack cloth to thoroughly clean off the dust. I also use low air pressure from my compressor to blow out any areas the tack cloth can't reach. Apply monokote over top. Makes a great substrate for monokote and helps hold out the wood grain. Caution: Don't put it on to heavy or it will bubble from heat of monokote gun/iron. Also, don't go crazy with the heat or you can get a bubble. This method has given me my best monokote finishes. Both the Jamison Special and the Oriental are fully monokoted.
