I have lead flashing which is working well but looks stained & unsightly - I have tried lead cleaner & plantation oil but with little improvement on its appearance. What grey / silver coloured Matt product can you supply & can recommend to make the flashing look new & more attractive?
Assuming the lead flashing is clean, dry, sound, degreased and prepared as detailed in the Technical Data Sheet we can recommend Rust-Oleum CombiColor Multi-Surface.
