Masked up and with some quick bit of black over the protruding bits of the first grey to get a dark base for the second camo colour.
>>10180268People do it every now and then to make less metallic finishes like aluminium dope, F-35 and F-22 skins, UK high speed silver paint, etc. Judging by that it works purely mechanically, but will (probably unsurprisingly) tone down the metallic nature of the metallic paint. If you want to preserve the metallic nature you'd probably need to use something completely translucent like Tamiya's X24 Clear Yellow (or just get a lightly yellow metallic paint, many titanium ones may fit). Filtering with yellow oil paints might also give you a tint at a not so great cost in metallic lustre, but likely not nearly as good as the clear paint.
