Rusting Fuel Silos and Gas Tanks
The basis for these bits of scenery come from the Necroplex Kickstarter – namely the bases, end caps, and a couple of support brackets. You can buy the Canister Pack directly from Necroplex.com now.
They were printed on a Cetus-3D in PLA at a 0.2mm layer height using a 20% infill for speed vs. strength.
Then I attached them to a few empty soft drink cans and roughly primed them in red and brown splotches - ideally, leave them to dry between colours or you’ll get the muddy-brown mess that I did!
Here are the vertical silos.
And here is the tank.
The next step is to liberally coat them with hairspray - any brand, but get the ‘firmest hold’ you can find. This will form a protective layer between the underlying ‘rust colour’ and the actual paint colour I want them to be. Sounds weird, but there’s method in my madness…
Once the hairspray has totally dried, it’s time to apply the top colours. However, before they dry I take a wet toothbrush (preferably one that nobody is going to use – unless you have a hated sibling!) and scrub/scuff away at various areas to reveal the ‘rust colour’ underneath. The hairspray is acting as a barrier so only the top coat is being removed.
If I wanted a more chipped/pitted effect, I would have sprinkled salt (either sea salt granules or table salt grains, depending on the texture I wanted) onto the freshly sprayed hairspray before the top coat stage.
This gives a similar effect to the chipping mediums you can buy for miniatures, etc. but at a fraction of the price – which is important when you’re looking at large/multiple pieces of terrain.
This next image is after the main top colours have been applied and ‘attacked’ with a wet toothbrush (to hit the main areas and get into the angles) and some kitchen towel (to scrub away and dab at edges to add shape).
Next up is painting the metal work and then (while it’s still wet) dabbing at it with more kitchen towel to remove bits and reveal the base rust colours.
Final touches are a couple of sponged on stencils and an overall grimy wash.
Here are the finished items – front view.
