The Rust Bullet® panel has slight blistering and undercutting along the scribe lines and none around the hole or the edges. There is slight discoloration and some loss of gloss retention.

The Wasser® Brand System panel is the second best test panel in the series and represents the peek of old technology. A significant rusting and undercutting is taking place at the hole and the edges, which indicates the difficulty of the system in covering sharp edges and corners. The scribe lines are undercutting as well. Like test panel #5 (Rust-oleum® Cold Galvanizing Compound), the three step Wasser® process utilizes a zinc rich under coat that provides a degree of galvanic protection, which is what allows the Wasser® System to do as well as it has done. Keep in mind that the use of a zinc metal undercoat brings along most of the problems of a zinc rich primer system, including environmental issues.
