Making my Bot more aged and used (lolz)

So previously I said I wanted to make my bot more aged/ancient looking. Like some one has abandoned it after a life time of use.

So after researching a lot of materials i wanted to replicate I decided on complete rust with details showing through. Here is the result haha........

Love the rusted look but its not convincing, I want more raw metal thats been worked and used
Like this!!!!!!!!!!!

I'm defiantly going to work up this shot for sure!!!!!! I love this one! more in th next post!
