As bizarre as this sounds ..... I think there might be some merit to it.
I remember something in the deep, dark recesses of my mind about a whitewash that used milk as one of the ingredients. This was a household paint so this might just work to some degree.
What we need is a guinea pig to try this method out.
Where's Erush ..... he'll try anything !!!!
Happy Modelling and God Bless
