Weathering PRX cement hoppers

Today I've used the extra day offered by a public holiday to tackle a job I've been putting off for ages - PRX weathering. 

I had bought a pack of Southern Rail Models' PRXs a few years ago not long before SDS models released theirs. The SDS version are to my eyes at least a better model. So for me the SRM ones are guinea pigs for experimenting with weathering techniques and will eventually end up sold on eBay or swapped with other modellers for more wagons I can't live without. I was really happy with the crushed pastel crayon technique I used on the PCC hoppers a few years ago, but I wanted to see if thinned acrylic paint will give the same subtle look I'm after for wagons that will have only been in service for about a year.

After first applying dullcote to all of the PRXs, I painted Tamiya Grit Effect Light Sand in small blobs around the domes, and coated it in a dark grey and then a smaller area in medium grey to give the texture and effect of dried cement that tends to cake on the top of these wagons. I did this about a year ago, but you could do this part of the process on a Friday night and be ready to do the rest by Sunday.

Next, I mixed together a few drops of Tamiya acrylic thinner, some XF-20 medium grey and about 20-30ml of water to make a thin grey consistency. I applied this with a soft-bristled brush, first liberally coating it and then dragging it down with the brush in streaks. The pictures speak for themselves - this worked better in some places than others... In future I would probably thin this even further and apply in much lighter layers.

I also gave a quick brush of the mixture over the bogies and visible parts of the underframe.

Not being afraid of wrecking these wagons, I went a little stronger with the tone and amount of paint than I really want for my era, but they still fit the bill for very late 70's/early 1980s first-contract run of these hoppers. I was actually surprised how much better they look on the layout under lights and running around!

In the time that it's taken me to write this post I've agreed to offload these two to a mate in exchange for two new, clean SRM NPRYs. Guess I won't have to worry about a market for these wagons when I eventually finish weathering all four!

I look forward to having another go and playing around with the technique, but I'm fairly happy with this as a first go.

'Til next time, cheers.
