Advanced vapour phase action deposits an invisible mono molecular coating on any exposed metal, leaving glass, plastic & wood unaffected. Anywhere air can penetrate VP90 will seek out and protect exposed metal surfaces. Forms a barrier impervious to attack from moisture and other corrosive elements
As VP90 will NOT absorb moisture it will not dry wooden gun stocks, therefore preventing cracking and splitting associated with heaters and dessicants in gun safes.
It will work regardless of the atmospheric humidity, and can even be used in conjunction with dessicants, if required. New VP90 now lasts 50% longer and protects a typical 5 gun cabinet.
