I use tissue paper a lot for inside cockpits when I am painting before mounting canopies. I stuff (carefully) the tissue into the cockpit, then wet the surface so it stays in place and does not shed.
I use unwet paper for masking a lot. If I want a mask to cling to the surface of the model, I use plastic wrap. I use tape along the demarkation line, then the plastic wrap over larger areas to save masking tape. I tape the plastic to the masking tape along the demarkation line.
