Painting lead flat roof above a bay window

[Moonshine]

I have a bay window with a lead roof as below.

 

 

 

There is an area towards the front which is covered in moss and growth that I want to clean off.

 

However when I clean it it also takes off the paint and exposes the lead.

 

Anyone got any idea what to paint the lead with to get black as per the rear of the bay.

I'm interested to see what should be used for this job.

lead should be left to oxidize and protect itself, any (to my knowledge) coating shortens the life of the lead by allowing it to degrade.

If moss is attached then i would say the coating is Bitumen

Perhaps someone used car under sealer ?

Original lead looks too thin and failed, renewed  properly good for 80 yrs.  never paint lead, insulate ceiling if you do take it off

never paint lead

 

Patination oil, when applied to new, stops it going white.

I don’t think of patination oil as paint and always use it
