MDF Polyster Coating

I am starting a new project that needs to have MDF coating, and i heard about coating the wood by polyester The technique might involve more than 20 steps of sanding and finishing. There's even a step where a special topcoat is applied in a dust-free room. The finish goes through numerous oven curings and hand sandings with extremely fine abrasives. Special glazes and polishes applied at the end help achieve the final, mirror-like sheen.

so is there anybody who tried this technique, to tell me the required steps,

thanks.
