Not only is this product of superior quality, it is easy to use, durable & easy to clean. I used it on the outside of my car (hood & trunk) as well as on the wheels. So it has endured the scourching desert sun, some freezing cold high elevation nights. It lasted through a few rain storms this season, and never peeled of due to any heat generated by the wheels &/or the brakes. As for clean up, brake-dust, mud, water spots and other road contaminant wipe off real easily. I use the blank sheets and cutout whatever shape or size I need. So it is very soft & easy to cut/shape, yet it can withstand the harshest of conditions. As for ease of application, it can be easily repositioned on nonpourus surfaces and never loses its strong hold or tackability.
This product was just what we were looking for. The lettering is crisp and professional looking and the instructions helpful. Not quiet enough of the more common letters.
