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.
