Wayne,
I like the stuff because it's about the thinnest tape around. Leave almost no ridge. But it doesn't go around curves very well (especially inside curves) and as I've discovered, the adhesive is susceptible to getting gummy over time. Probably my fault as I was using an old roll. I broke out the stuff still sealed in the package and it was fine. A lesson there in making sure it's sealed up between uses. 3M tape is cool because it goes around curves really well, but it's a bit thick and leaves quite a ridge.
I use a lot of different tapes when taping for trim: 3M vinyl tape, the Finesse stuff, some really odd stuff I picked up at the paint shop that is a crepe type tape (like masking tape) with a lacquer edge that leaves a really sharp line and some other various stuff I've picked up along the way. I also use electrical tape because it can be cut into all sorts of shapes and never pulls up paint. I'm getting to the point were I can pick out the right tool for the right job.
Just as a sidenote, I found some stuff for doing masks that works better that Frisket or anything else I've tried. It's an Avery product: 8665. It's a sort of full sheet label stuff. I've been using it for doing stuff like checkerboard. Sticks really well, doesn't pull up paint, seems to be oblivious to clear shot over the top of it and so far hasn't leaked any paint underneath.
This paint scheme is quite different than previous stuff. No colors butt against each other so I was able to tape the whole thing at once, Sort of weird because I shot the first color, covered it up and shot the second color. There's a lot of bleed over the as yet unpainted areas, but it really doesn't matter since those areas will be painted with another color later. Just kinda weird compared to what I usually do, but a lot less labor intensive.
