I wasn't real happy with the double-sided tape that came on the monochrome M3 badge I bought...it was yellow and visible even after I filled in the edges with black sharpie so it made it look cheap to me. I got tired of looking at it and noticing it every time so I finally took it off today.

The cheap part (which wasn't cheap, actually) left me a little present on my thumb. The adhesive might have been ugly, but it sure was strong. I'm just glad it didn't damage my paint. It's nice and smooth now :D
