Greetings Paul,
I didn't watch Ron's video link, so forgive me if I am repeating.
Just my opinion and experience:
Frisket was developed back before CAD illustration took over, when graphic art was done on poster board or similar paper products. It was low tack so that it wouldn't damage the original artwork underneath when it was removed (or repositioned). It was clear (or nearly so) so that the artist could lay it over a line drawing, and then (very carefully so as not to damage the paper or board beneath) cut away where the color or shading would be applied (usually by airbrush). it was thick so that it would be easier to feel the cut, and so that it could be reapplied in the same position so that you could spray an adjacent area.
As a result of these characteristics, (low tack and rather thick) it doesn't have much use in our modeling. The thin low tack tapes from 3M and Tamiya are much better for the curves that we have to deal with. I only use the frisket on dead flat things like masking a windshield for wiper marks).
Hope that helps,
Bill
