Put together this 30 second video a while back, it’s worth seeing if you want to know how easy it can be to remove graffiti using our graffiti resistant films on signs. Using some rubbing alcohol on a paper towel, the tagging was gone in moments.
Demonstration of removing graffiti from a vinyl film laminated with Concept 108 Tedlar Anti-Graffiti film. Graffiti sample had been on the film for about 2 weeks, and is removed with the proper solvent. I try three solvents as a test.
