After my introduction to P4 with Exactoscale track and it's steel rail I've wondered about tinkering with my Nickel Silver railed Peco Code 75...

I'd read in Martyn Welch's 'The Art of Weathering' in my teens about using gun blue to get Nickel Silver to look like steel. I wondered if Carr's Steel Blackening fluid would work? (they do a specific Nickel Silver version - not sure whether that would have the same effect as this). So I tried it on a demo piece of spare Peco Code 100. Left hand rail was treated with the fluid, right hand rail wasn't - you can visibly see the difference.

Success - I'd say!

So on to Paxton Road!
