This shiny aluminum trim is used anywhere you want to hide a seam on a trailer & does not have sharp edges (the edges are rolled). Commonly called chrome trim (but it's not chrome). It can be bent around a gentle curve. Fasten with glue & rivets. Because of shipping, scratches are common for this product & can be buffed out with rubbing compound and/or a bench grinder with a buffing wheel.
It is sold in 6 foot sections
