I HIGHLY recommend this tape for hobbyists over generic painter's tape or other brands of hobby tape. Tamiya in general makes some really good products, including their paints. This tape is strong enough to stick but the adhesive is not so strong that it's going to damage your model or any well-cured paint under the tape.
For curved areas of a model, use much shorter lengths of tape, with the length being dependent on the sharpness of the curve, of course.
One other tip: Right before painting, I usually run my finger over the applied tape edge one more time to make sure it's sticking well. This is especially true if the surface is slightly uneven -- for example, a submarine with rivets detailed on the hull. You just want to make sure the adhesion is good and tight right before you airbrush, spray, or brush paint.
This is, in short, good stuff. Make it even better by getting the appropriately-sized Tamiya dispenser.
