Just got some models from e-bay, space wolf wolf guard and long fangs, but what the photo didn't show was that they'd all been rather poorly painted. Now I'm not talking "OH GOD WHAT IS THIS EXTERMINATUS" level here, the original owner seemed to have just given them a blotchy/half-arsed layer of The Fang and given them a wash effect and nothing else. Many grey areas show through, and it's obvious he didn't even base coat them.
I would like very much to just spray them over in Chaos Black and then a can of The Fang to get a proper coat on before I start detailing them myself (that and as is they're a much lighter blue as they lacked the black basing I've used, I dislike the 'baby blue' colour
SW armies tend to have these days

).
So will spraying them once with Chaos Black and again with The Fang ruin them? Or will the fact it was a -very- thin layer of paint mitigate any loss of detail?
