The candy painting

The parts are covered with a phosphate finish for aluminum and it is then annealed to 60°.
This is required to allow full adhesion of the Candy paint.
It is then covered with two layers of a matt metal grey base, two layers of Candy paint.
The tracing patterns are stuck and then covered twice with two layers of polyurethane varnish.
They are then water-sanded manually. A 30-minute anneal process to 60° is finally applied between each layer.
This unique method guarantees a faultless finish. It also ensures getting the same color as the CR' s.
(All items painted in orange Candy are painted identically).
 
Anecdote reported by the Hansen Team during their last visit in France
In Daytona, the motorbike has been accidentally painted in the wrong color.
The deadline was too close to allow redoing the whole painting work.
The motorbike remained in this magnificent orange Candy color which is somehow very delicate to use.
