Breaking myself in gently to metal tracks I got hold of the Easy Link ones (thanks to Mr T pointing me in the right direction for a set). Having cleaned them off I put them into some AK burnishing fluid, but despite good agitation they came out with quite a few missed spots. I assembled the runs anyway which was very straightforward, apart from them having a tendency to curve away from the extended "winter" section, but that sorted itself out after working them for a while
Here they are looking a bit funky after the first treatment.
Once built up I tried a technique I'd seen used by Martin Kovac on the Night Shift channel, just brushing the fluid on rather than immersing them. That seemed to work well, used much less fluid, and evened up the finish greatly. Several test fits were done to make sure I had the correct length, then I gave them a good going over with various dry pigments
While I had the pigments out I splashed them around on the lower hull. I had to do this a couple of times as I kept getting bald spots where I'd applied pigment fixer. Nothing earth shattering, but I feel like I'm getting better at it each time.
