Can you see the difference?

Today I continued sanding the hood.
After a while I had one half done. Can you see the difference?

 A while later the other half was done. And I had to touch up some parts with the spray can primer.

 I then turned the hood upside down and spryed some sanding guide coat.

 And then I started sanding again. At the end of the day half of the underside is sanded.

The rest will be for tomorrow. And after I sanded the hood I will continue with the last for big parts.
