My team has been debating how to display our sponsors and team branding on our robot this year. Traditionally we have used printed vinyl banners that were attached with Velcro (that never stayed on long enough) and eventually zip-ties. We found that it was annoying that the banners would tend to fold, and that they had a tendency to fall off or to be a complete hassle to remove (and nowhere in-between

).
This year we were thinking of using 1/8" green polycarbonate with stickers for the images we wanted. This would make the robot signage far sleeker and more stable yet also easier to remove. The problem with this however, is that we are very worried that the panels will get broken (they are on the edge of our frame perimeter due to the density of our robot). Can any teams with experience with polycarbonate signage offer some help?

Thank you!
Also, if anyone has a suggestion for a good custom sticker company ,that would be helpful. As we are having trouble finding local companies that can do that.
