Weathering Techniques

[Greedo]

Hi fellow Tree-Dodgers!

 

I'm about to finish my build and am starting to research weathering.

 

I'm striving to get Lancer and to be as prop-accurate as possible.

 

I am, like many before me, very nervous about unleashing spray-paint on my beautiful armour, and since my only previous build was an ESB TK, I've only got experience with the old wet newspaper.

 

Any tricks to get close to the original? I don't have access to airbrush equipment, so is there a way to get there without it?

 

And a specific thing: These black/dark streaks or scratches all over, that I think look really awesome and are what really makes or breaks weathering. How to do them? Black paint on stick and rub over?

 

Thanks!
