I got that sticker
from here. I got stickers from before too. The letters come on a film, after application you wait a bit and peel the film slowly off and only individual letters remain. It' looks very good and it's weatherproof. The hazard tape doesn't work very well on small size tubes that curve even a little bit, it's stiff and creases easily. On my trailer I didn't care but on the BD I want it to look nice. Don't worry, I'll think of something.
