Right, on with the weathering.
I have spent a good deal of time thinking about how to weather these coaches. The original client brief was for the finish to be "slightly tired", which I take to mean just a light weathering overall, rather than completely covered in grunge.
I started with a study of as many colour images of coaches I could find to get an idea of the general pattern of weathering of in-service vehicles. From what I can glean, the body sides were kept fairly clean, either washed down manually with a mop and bucket or through a mechanical cleaning plant. Grime would accumulate in nooks and crannies, around hinges and handles, essentially where whatever cleaning system that was used failed to clean. Underframes and roofs, of course, got pretty filthy. A combination of rail dirt, brake dust and general grease and grime soon caked the underparts and bogies, while the roof was fair game for anything deposited from above.
The Mk1 carmine and cream was susceptible to fading due to cleaning chemicals, and also failed to protect the steel bodywork from the elements as well as might have been hoped. Various causes for the onset of corrosion and paint damage were found, which led to better paint technologies and better methods of application, but I digress.
So, the finish I am looking for is coaches that have been in service since new for about five or six years. They've been through the regular maintenance and perhaps general overhaul, but otherwise have been earning their keep on a steam-hauled railway to points west from Paddington.
I also read and re-read Martyn Welch's bible on the subject,
The Art of Weathering, which gave me some clues as to techniques I could use.
I am not confident with airbrushing for weathering. I feel I should get that out there right away. I have used the technique, but not recently. My worry is always I would make a mess, and I spent some time considering how I might have to mask off the sides to spray muck up the ends of the coaches. Add to this the fact the temperature in the loft workshop is not conducive to airbrushing, plus the faff of mixing and thinning before I even start, I decided to try just good old dry brushing instead. All excuses, meaning I should really get some old coach sides and practice the technique. Consider that added to my to-do list.
I used my well-worn aluminium foil pie dish, splodged some matt black, earth brown and orangey brown enamels into it with some thinners, and mixed things roughly much as an artist does with a palette of oils. Using a No10 sable flat brush, I loaded it and took a wodge of plain kitchen towel, and first squeezed most of the paint out of the brush. I then wiped even more off the brush until almost nothing was being left with each stroke. I then set about the solebar and underframe areas. I built up the colour slowly until I felt confident in my technique. The secret, really, is knowing when to stop.
If I felt I'd overdone things, I added more black into the mix, and went over the areas again to tone them back down again.
The bogies need more work than the underframe. To begin with, I did the basic dry-brush of the grunge colour, but only really to highlight raised detail. Once the paint is dry, more attention will be paid to areas of rust and oil to bring the detail out properly.
Next I tried the ends.
With lots of handrails and raised detail on them, the ends posed a bit of a problem for dry-brushing. I wanted to try to get an even coat of dirt up the ends, which would match what I'd seen in the prototype photos. Where I could, I brushed downwards to give an impression of rainwater running down through the dirt. I had to revert to a smaller flat brush to get into some nooks, but I think the overall effect is what I hoped to achieve, though not quite as even as it could be. The passenger end of the BSK seems a little overdone, so I'll revisit that and see if I can either tone the effect down, or match the other end to it. I might well have to break out the airbrush to give an even tone after all.
That's as far as I've got with the BSK. I'm working under artificial light, so I before I do anything else I'll wait for daylight and have a really critical look at things.
Next up, the roof, and then I'll tackle some mild weathering on the sides.
Incidentally, dust is really,
really annoying me.
You can see specks adhering to the inside of the windows, even though I have blown and brushed the interiors until I'm blue in the face. Where does it come from? I'm considering an investment in one of those silly PC keyboard vacuum cleaners to aid with dust removal, because I'm getting more than a bit narked at being laughed at from behind sealed windows by specks of white dust!
