Here at Procutsigns we have been using this for about 2 years with excellent result. There is a learning curve with this product and you need to follow its directions to the letter to apply. We have used it successfully with striping on vehicles,motorcycles as well as signs and designs on almost any substrate. We have found a video from 3M that will be a great help to the first timer. We will be adding some in the near future.
Good luck and happy creating.
