Weathering rusty iron roofs - A how-to guide

Hi all,

Another update and some weathering tips. My PC is still under repair. Most of the problems are sorted, but it's now getting some updated parts, extra USB ports and a new I'm posting this from my way too small keyboard on an older-than-I-am, very slow, laptop. With a battery that lasts five seconds!

I joined facebook a few weeks back and I was asked how I weather iron roofs on my sheep wagons. So I will do my best to show you all how I did it, and I've included pictures. You can find this Facebook page at:

The first thing is to prime the roof with white primer. I use Turpentine based primer, not automotive thinner based primer, as the turps based takes longer to dry allowing the primer to stick to the surface. "Turps" primer is found in most paint shops, hardware stores and "discount stores".  If you not sure ask, and if they don't know, you are better of  shopping where they know the product. 

Turps primers white and gray - I often used gray first, then a light cover with the white
In this case I only used the white as it covers well over plastic..

The next pic shows the white primed roof with some brushed silver in random spots.  

Now coat the roof with Dullcoat as this will allow the Dr Bens weathering pigments to stick

Next you can add some Dark Damp rust pigments around but not over the silver. It will cover well over the white primer.

Now add fresh dry rust making sure you keep some of the dark rust showing and give the whole roof a light dusting with the dry rust. Now I cover with a light coating of dullcoat and reapply pigments, that is if some of the weathering has been toned down too much by the dullcoat.

And there you have it. A weathered rusty iron roof!

Later Deano
