Am starting my first touring car shell, and instead of making things easy, I plan on using 3 colours. I don't think the design will be too complicated, but does need for all three colours to meet at some points. I find applying masking inside body shells to be quite difficult, so was thinking of masking everything, spraying black, then removing that layer of masking, waiting plenty for the black to fully dry, then applying more masking for the second colour, before removing that and spraying the final colour. I plan on using satin clear over the masking before the colour, to help stop any bleeding. Any problems doing it this way, or is it a must to apply all masking in order and remove the required sections after each colour?
