Is the PVD Finish worth all the extra cost? .. How good is it?

Is PVD worth all the extra cost? .. How good is the PVD against corrosion protection?

YES .. however when you speak of costs .. everything becomes subjective - PVD is a super-hard coating that is by far the most durable coating available on hardware today. The superior quality will outlast any traditional painted finish or coatings. Especially desirable on highly used parts like door handles etc.

How good is the corrosion protection? .. Most of the industry standards are based on neutral salt spray (ASTM B117) or CASS (Copper-Accelerated Acetic Acid-Salt Spray)(ASTM-B368). Zirconium Nitride (ZrN) has shown to surpass 1200 hours of neutral salt spray and over 150 hours CASS on electroplated brass.
