Absolutely amazing. Used it to tape letters that fell off the back of my Subaru. After completely removing the previous dried dirt and cutting some of that tape right along the back of the letters, I placed them, pressed with my hands for a few seconds and voila. Did. Your hands should be clean without lotion, and the varnish should be absolutely clean and dry, without traces of grease and dirt. Do not touch the sticky part with your hands or anything other than the item to be pasted or its last place on your vehicle. I made sure I got it right the first time by drawing a straight line with a long ruler and pencil before placing the letters because with that much embroidery power it would be impossible to adjust them later.
