That tape looks great, but it looks like it's very easy to mess up putting it on the rim. How do you make straight tape go around a round rim without buckling and wrinkling? Also, how do you keep a consistant distance off the edge? Looks like a lot of work.
Better if they sold a round piece that applies directly on, methinks.
Looks great if your can do it neatly, tho. I'd love to have that on my rims, but I don't think I'd like to go through the ritual, as I'd probably screw it up.
