According to my experience this solder is a nightmare for automotive work .It simply doesn't adhere well to the metals commonly used in cars. On the upside, it is precision soldering wire. However, it's not worth the hassle if it does not do the job it's meant to do. Save yourself from the frustration and get a better solder for auto work..
