I have just a started putting together a Grandt Line Corrugated Iron Warehouse kit. The corrugated metal walls are molded in gray plastic. The instructions recommend painting them with aluminum paint. I am sure there is a better method to make a realistic metal wall. And I am sure that there are many of you that could tell me how. So please give me some of those great ideas. I am really itching to get this kit together.
Thanks

Aluminum paint will make it look like a new or well maintained(recently painted) building.
Going for a lighter shade of grey will make it look more weathered. Then you will want to put rust marks on. How much and how rusted is your choice. Go take some pictures of buildings with corrugated metal roofs, They tend to rust more between the rafters and at the ends of the sheets. Dry brushing usually works well. Another technique is to dry brush on little stipples of dark brown (burnt sienna) artists oil paint and then wet brush thinner down the corrugations from the oil paint to make it look rusty.
I am resonably happy with the results using silver or aluminum paint (my favorite is Floquil Old Silver), then weathering it with dark gray and rust washes and chalks. A friend of mine uses actual scale corrugated metal pieces cut to scale sizes, then weathers it as above. His look better than mine but of course therre is a lot more work involved.
Good luck!
First I painted the corrugated plastic a dull aluminum color. Then I took a very sharp pencil and drew lines to indicate the edges of the sheets. The vertical lines went full length of the roof at 30" spacing. For the horizontal lines I measured slightly less than a standard sheet length (8’,10’,12’ or 16’) across between two of the vertical lines. I went slightly less to indicate overlap To look most prototypical sheet length should not be the same in each row, but alternate rows. Example would be a 18’ span using 2 -10’ sheets alternating with an 8’ and 12’ sheet. Make the top sheets full length, indicate overlap with a shorter lower sheet.
Once the lines were drawn, I lightly weathered each sheet a little differently, with one or two quite weathered as though they had been wet in the stack before being put in place. The newer the material, the less weathering.
Good luck,

I use silver rattle-can paint, and then weather it to taste with weathering powder. Then I give it a coat of Dul-Coat, which seals the powders in and dulls down the silver so that it looks like corrugated metal.
LION used ribbon wire from dead computers to make a wall. They also make good roll up doors and catwalks on elevated subway structures.
Here the LION used silicone glue to put the material on the wall, and then painted it black. The paint of course will not stick to the places where the caulk was slopped, but that gives it the appealing pealing look of the prototype.
Paint plastic light flat gray then dry brush rust colors.
To look like this:
Wdcrvr,
If you have the,NOV. issue of MR. there is a article in there called: 12 Classic Weathering Tips,page 44,that has a lot of great ideas,that you may enjoy or employ…

One of my first buildings I painted using Polyscale paints brought me to he first hurdle of basically what you are describing. I had used the Shiny Aluminum color and it looked… well bright and new. I had first tried using some washed out grime to give it a different color and pattern.
I also had the Polyscale paint Rust color and mixed the two together to get more what I wanted. Afterwards I sprayed it with Dullcote to take away any shine.
Since then I’ve also used photos ot various sorts and tried to study what I was seeing in the pics. Colors of walls of various buildings have certain traits. Take for instance a building that has windows with metal rusting and dirt / grime accumilating on window sills. When it rains, all this debris runs down over time and leaves stains. Even certain walls of buildings have a splash of color from dirt and mud from rain… at the lower end of walls. So many little things that makes painting fun. I’m sure others here in this forum could add to this, but I just wanted to show you my first attempts and tell how I went about it.
