Hi Nigel,
Thank you. In describing the distressing of the J70s, there will be a degree of duplication in the images I post.
Again, no air brushes were harmed. Paint was confined to a squirt of Humbrol Dark Earth ( no.29 ) applied to the lower parts and sprayed directly down onto the upturned bodies/skirts/ chassis frame etc. Paint was also applied by brush to the cab floors as detailed below. The colours referred to are as per colours of the Humbrol weathering powders.
The only chassis sprayed was that of 68225, the non-skirted job. The other two chassis, being hidden by the skirts, were left well alone.
So, first job was to dismantle the locos, in particular, removing the "wooden" bodies from the chassis and then removing the boiler assemblies. In doing this, reference was made to George Dent's article in the September 2022 issue of Model Rail.

Here is 68223 stripped down. The blue tools etc are from a mobile phone service kit acquired from Amazon which made the lifting of the wooden bodies so much easier.
The skirts and chassis frame were sprayed next as described above.

At this point, I masked off then painted a plank effect on the cab floors at each end using a mixture of humbrol 103, mast oak and number 29, dark earth.
Details were then picked out on the boilers as below.

Once happy, I applied a mixture of smoke, dark earth and dark rust powders to the boiler. All was then sealed using number 49 Matt Acrylic Varnish from a Humbrol Aerosol.
Attention then moved to the skirts.
Some rustage was suggested using dark rust and iron oxide powders applied very sparingly, mainly around bolt heads.
More dark earth weathering powder was applied, mostly working upwards from the bottom of the skirts. Some smoke powder was applied in a downwards direction "Highlights" were added to the edges using white. Top edge working down, bottom edge working up if that makes sense.
A few more photos.

Dark Rust was added to the skirts, mainly from behind, then toned down using smoke powder.
Here's an out of sequence image of the skirts..

On the chassis frame, bolt heads were highlighted using a pencil.
Again, a cropped out of sequence shot highlighting the bolt heads.

Everything was then sealed using the matt varnish.

Next, I'll describe the weathering of the bodies.
