Building silos

I have been doing some trials on the silos that need to be built for Shore Fertilizer in Date City and the acid tanks that have to be built for the phosphate plant at Knights.
The first step was to find the right PVC pipe.

This was after the pre shading.

 

I shot the first coat of light sea grey on with my airbrush.

 

 

And this is what it looked like after the second coat.

 



Here you can see the new silo next to the old mock-up's.
