Sorry, it wasn't as fast as I would have liked but we did do some experimentation today with this tape.
Short answer is it works pretty well. It laid into place as easy and with as much control as laying in striping tape. Once we figured out a couple of tricks to control the mono-filament it sliced through 3M 180c / 8519 laminate neat & clean. We tried some straight applications as well as curving awkward lines. Both seemed to work equally well.
The resulting edge definitely requires attention and making sure you flame the edge and set it properly. Basically just like you would properly set a cut edge.
I would think it would be useful around tight corners where a cut is needed but difficult to control knife pressure. Very useful in areas where a panel seam needs to be modified or an overlapped edge needs to be trimmed back without risking a nick in the bottom layer.
For those who have the blade skill to trim off vinyl without touching the surface... not so useful of a product. One big advantage I see here is the capability of putting another tool in the hands of wrappers in training as they continue developing their critical knife skills. If you have people who are skilled in wrapping & squeegee work but still need to work on their "touch", this is useful to keep them moving without risking a client's paint job.
I believe we will keep a couple rolls of this on-hand on a regular basis.
