I used this tape to define the back end of a 20' flatbed trailer. I'm pleased with the result. This tape illuminates reflected headlights, even in fog and heavy rain. It adheres well, even to metal that's not absolutely clean, bright, and shiny. This roll was plenty to tape my trailer, including the bottom rungs of the ramps, which are of course up in the air when they're pinned up for transport. I'm pleased with this purchase.See full review
