Assuming you haven't thought of it already, you should also use painter's tape.
Its usually blue and looks just like masking tape. The adhesive is gentler, since
its main purpose is for masking surfaces that are to be painted.

If you are using an airbrush you shouldn't have to mask it at all just card board pieces to block spray. To put on the stripes use a coat of semi gloss or dulcoate.
