You don't need to buy the marbilizer, all you need to do is use a basecoat color of your choice, over-over reduce it with very slow reducer, add any special additives ( pearl etc to it if you want) then spray and use your painters plastic or saran wrap or aluminum foil or what ever to mess it up. Of course I spray it on with a med coat, immediatly apply painters plastic, let sit for a short while and remove plastic, change color in gun and continue to layer my colors for a deeper looking marble. You can even take a hand brush ( veining brush) and lightly draw in some cracks or veins, it gives it a great realistic look. You can then Kandy coat or clear coat it or what ever you want, to finish it.
