You may remember the green LRMBT with the broad white and orange stripes. I did the salt and hairspray on it and duly transferred it to it's new unit with a smart new panzer grey livery.
Which I promptly attacked with warm water and an old, soft, toothbrush (actually a teethbrush, I still have most of them).
You can see the green through there as well. I'm pleased with how this turned out.
Where the clean up lifted the orginal paint up, humbrol enamel bare metal turned real damage to deliberate weathering.
Still a bit more to do - another coat and wash on the hatch liner, homogeneity for the mud on the tracks and a bit more mud'n'rust.
Even as I write this, the decals on yellow to match the markings on green have been applied.
