Our warranty stickers come with a permanent adhesive and should stay in place for many years to come, (the original labels I did over 10 years ago still look like new) but they are still just labels. If someone wants to these warranty stickers off, they will come off. With all the different surfaces that people stick them on it is impossible to predict how well they will adhere. You can help though by making sure the surface you are applying your warranty stickers to is clean. By wiping the surface with some 91 percent isopropyl alcohol first, you will clear away any dust, dirt or fingerprints that will affect the adhesive of the warranty stickers.
