Could I ask what you used for the oil stains on the Mobil Charringtons tanker around the ladder?

I use a mixture of things, mainly AK Interactive washes, etc.
On this occasion I used AK Track Wash as a base, let it dry thoroughly and then dip a broad flat brush in White Spirit and stroke downwards removing some of it, to what I think is acceptable. Then I use a mixture of AK's Fuel Stains and AK Kerosene stains, applying bit by bit until the effect has been reached.
If I remember I did use the Airbrush to effect some black staining over the upper areas.
I purchase most of my AK Interactive products from Scale Model Shop

They stock AK Interactive products such as Weathering Effects, Filters, Pigments and washes.
They also stock the Ammo MIG range, which again are excellent products.

… would it be possible to you to explain how you go about some of your weathering please?

… there is a sequence that I follow.

1. Strip sides off open wagons
2. Remove wheels and brake discs
3. Mask and patch paint, etc
4. Transfers and Varnish
5. Reassembly
6. Weathering!!!!!

For weathering I tend to use certain products, mainly from the AK Interactive range and also the AMMO MIG range. I use filters, panel liners and washes (all enamels) which are teased and removed in part with white spirit on either cotton buds, ladies make up sponges, etc.

For pigments I use Pinnacle powders now as I find they adhere better. I have used MIG powders before, but I now prefer Pinnacle.

The whole process is not to change the colour with an abrupt shade/colour, it is to alter both the tint and the tone of the colour with gradual shading into darker, more mucky areas.

This can be achieved with the above washes etc, and sometimes I will leave a wash 24-48 hours to dry off before removing most of it, depending on the look that I'm after.

And lastly, try to look at the pictures of the real thing, or what is around you. Nature is the most prolific weatherer!!!

In addition to my post above about my methods.

I do use an airbrush from time to time, but to be perfectly honest, the airbrush is only to blend everything in. On some of the pictures above, no airbrush was used, as I'd already obtained the look I wanted.

I believe that airbrush weathering takes up around 5 - 10% of the overall work.

The only time I will use an airbrush to a greater degree is when I 'soot' van and coach roofs.
