I've only found one 3M product that I was disappointed in and that was a foam polishing pad for a buffer. Being they're a MN based company, (3M stands for Minnesota Mining and Manufacturing), I try to use their products whenever possible.
So that's good to know!
When you get to the point of applying them to the sail, ask here - I have some hints and tricks for you.
I expect to upgrade to some wide format (larger than 48") printing and cutting equipment in the spring/early summer of next year so we'll have full size graphic capability to do boat wraps and large sail graphics. That's part of the motivation behind the new garage and workspace I've been working on.
