If you plan on mixing paints, please try on a piece of scrap wood first. If you do find they react, you don't want to have something reactive sinking into the guitar and that you then need to sand 1mm or so off the body to remove.

And 'reaction' may not be a near-immediate bubbling (though that can happen) but could result in the finish never hardening properly, which takes a long while to realise (this has happened to me in the past).
