To ensure a good bond for ground points on any metal surface in the car,
proceed as follows:
- Clean the area around the bolt hole down to bright, shiny metal. An
easy of doing this is to use a pilot bonding end brush in a drill to
clean around the hole (see below for where to get these brushes). If
a brush is not available, scrape all paint off of the metal around the
hole and then use sandpaper to get a perfectly clean surface.
- Once the surface is cleaned down to bright, shiny metal, coat the
surface well with any conductive, anti-corrosion surface compound, such
as Kopr-Shield (see below for where to get Kopr-Shield).
