Ultra High Strength
The addition of ultra high strength steel in the A Pillar, B-Pillar and cantrail gives the body greater strength in a front or
side impact.
No attempt should be made to straighten ultra high strength steel, due to its brittleness.

Aluminium
Aluminium 6000 series is used in the hood, tailgate and liftgate. It is made from magnesium/copper aluminium alloy and is
heat treated during manufacturing/paint bake process resulting in a panel with increased strength and dent resistance.
When repairing aluminium you must use tools that have only been used on aluminium and never on steel panels, this is to
prevent cross-contamination
