Process: The Ferrari 250 gto

PRPOCESS 3

I find a tracing paper, and cover it on the car. Also I mark every tuning point. 

Then, I use knife to cut the tracing paper on top of the aluminum piece. Then, I use mark. 

Then, I use this two tools to curve both sides.

The both sides getting curves and looks great.

Then, the aluminium already curves to two ways.
