I used it as a testbed to make a hull look old and rusted, so I can randomly put this on an RC battlefield.

It just looked so empty!

I have to find something to solve that...

After a quick spray of cheap grey primer I covered the whole with one of my favourite weathering materials: Vallejo Rust Texture!

I added random bits on to the inside simply to make it look more interesting.
Prolly a Rivet Counter's nightmare haha!



After some more Vallejo Rust Texture
Then I added some more color variation using a brush. (AK Rust Primer and Track Primer).
