Anyone here paint cars as a hobby?

yes i paint a lot ...i went to auto school for painting ...thats where i learned how

the main parts of paint are resin, pigment, binder and solvent so as long its of a similar resin ....i would mix and match stuff around

Omni is a PPG product but it is a different resin but similar ....different resins will cost different ...i would definately mix it with Sikkens ...sikkens is kinda expensive though ....the other brand you mentioned im not familiar with that .

as long as your not mixing uerathenes, with enamals or laquers and as long as your not traping solvents in ...i dont see why there is not flexibility in mixing....if you keep track of what your mixing.:coffee2:
