Proper primers (that "etch" into the material) shouldn't come off on the mould. I've never had a problem priming with lacquer based acrylic primers (i.e. Tamiya Surface Primer, Mr Surfacer, etc.) and in fact find it very beneficial to prime master parts with such products. Not only does it provide a nice, smooth, uniform surface for moulding, but the uniform grey lets you get a perfect idea of how the part really looks!
Oh yeah I can make that....
