This tape stays put, removes with no residue, and does not leak through even with heavy coats of paint. For masking glass canopies, I lay the tape down and cut the edges with a xacto knife. Because this is a paper tape, there are some fibers left over on the edges, but it doesn't affect the end result. This tape lasted me through more than six models, and the 6mm width was just right for every one of them. Also, try not to touch the sticky side with your hands before using it (obvious, I know)-- it really affects how well the tape will stick.
