Calder Lead - Step Lead Flashing and front Chimney Apron 

Hi StuartUsing Patination oil gives the lead a protective patina that will help reduce staining and give the product a great look for years to come.RegardsCalder Lead

Many of us roofers now use oil to bring the shine out. Looks much better. However this video is all about selling their products.

brings the silver shine back out! its purposely made for lead. :)
