If I painted an object that has no chips or dents, but is already painted and lacquered/varnished. Can I psibt over it, and get perfect results?
That depends on the paint you apply to the existing finish. There may be compatibility issues. For example, applying an emulsion paint over lacquer or oil based gloss paint without any preparation is likely to result in a poor bond leading to the emulsion flaking off: you would need, at minimum, to sand the surface with 80 or 100 grit abrasive to create a key, but even after that, emulsion paint isn't designed to go over this type of finish, and less than optimal bonding is a likely result. Then there may be wax, dirt, grime, silicone or other contaminants on an existing finish to impede a good bond. De-greasing would be a necessity with, for example, white spirits, sugar soap, etc.
In reality, as others have said, the quality of the finish largely depends on the quality of the preparation, although, naturally, the skill expended on finish application has a significant role. Slainte.
