Genuine Suzuki Accessories custom trims are created using Auto CAD 3 Axis design software. Exterior grade urethane is used in production. It is a “memory” urethane, meaning any impressions will disappear in minutes, returning to its original shape. It will not fade, crack, yellow or harden. (Beware of cheap imitations; most of those manufacturers do not use this material.) 3M VHB Automotive adhesive tapes are used for securing the trim and are removable. When installed correctly, the adhesive will not fail, period. Made in USA.
