“Indoor storage” describes the storage of ferrous components in closed store-rooms having a relative humidity of
60%. Increased protection times could be achieved when treating finished surfaces or store the parts in a sealed
pack.
“Outdoor storage” describes open storage, which assumes primary protection from the elements by tarpaulin or
other form of cover.
Influence of temperature may cause some cloudiness, which is reversible and doesn’t have an impact on product
quality.
If required protective films of Rustilo 4163 can be removed by using a petroleum solvent or alkaline process cleaner,
