I’ve been building models for 35 years and have used Vallejo since it was really first available in the States.
Now to the problem…I’ve been airbrushing the joints on my kits with primer and then Mecha Dark Steel. Once I get the parts assembled such as the thigh and calf, when I then position that leg, the armor scrapes away the Dark Steel I put on the joint.
Are there any tips or tricks to prevent this without switching paints? I can’t use anything overly toxic since my 10 year old daughter builds at the same time I do.
