How to make spray paint masking for automotive parts

HI, now I am trying doing automotive spray painting masking(masking to close the area no need to spray painting of automotive part) . my self is beginner of doing this process .Now I already have the solution of CuSO4 and already setup the plating bath and other equipment. My problem now is how to use the conductive paint (conductive copper powder +thinner)to stick on my automotive part (ABS material).When I spray on ABS part ,
after a while it easy to peel of by scratch with finger
