Okay, I purchased some Frog Tape, and in the spirit of ShurTech Brands' risk avoidance, I ran a Consumers Reports-style torture test:
I cut some tape into sawtoothed masks and applied it to unpainted plastic, lacquer-primed plastic, and (as a nod to the product's origins: painting wallboard) raw card stock. I pre-wetted (just running a wet brush around the sawtooth edges) half of my samples.
I brush painted all the surfaces in two colors (a thin, flat yellow vs. a textured "rust") of acrylic plus one (Pactra RC83 Polycarb Fluorescent Racing Red, flammable, contains ketones and other nasty stuff) chosen to "punish" the tape.
The day after the first coat dried, I put down a second strip of Frog Tape at right angles to the first layer of flat paint to see if the adhesion would tear-up the base coat. (I can't think of any reason anyone would do this normally, but I wanted a torture test.) I painted over the second mask and let the whole mess dry thoroughly.
Now what DIDN'T I do? I didn't run my test masking a compound curve. I didn't do any spray enamel or airbrush work. And (BIGGIE!) I didn't test any other masking medium [MATT USHER, ARE YOU LISTENING?].
The results: The tape came off easily and almost pristine! The worst was the wetted tape on raw plastic (my aggressive brushstrokes got under _one_ of the sawtooth edges) and that was still much better than the last time I masked a straight line. The dry and wetted tape on lacquer produced indistinguishable, top-of-the-line results.
The real surprise was the rusty glop on card stock; I'd expected a broken line, and what I got was laser-straight, clean where I'd masked, ugly as homemade sin where I didn't.
And in the adhesion tests there was no pull-up. This stuff is GREAT!
