This is a great addition when you are using the wet method to apply your adhesive vinyl. A lot of crafters just use dish soap and water to do the wet method, but if it is not mixed properly and you add too much soap, you can seriously weaken the adhesive glue on the vinyl. The rapid tac is specially designed for the wet method and you will never run the risk of weakening your adhesive, it actually enhances the bond between your project and the vinyl. It also makes it so much easier to clean the surface and apply your vinyl. Professional sign installers use this formula when applying their adhesive vinyl.
