Painting a War Memorial

I actually took a class on copper oxidation, in regards to roofs.

If the plaque is copper, after 15 years it would probably be dark dark gray.

If the plaque is bronze, it would probably be still a dark bronze color, but with a black cast to it.

It's usual to paint, wax or otherwise protect plaques.

Is the plaque really copper, or is it bronze?  They do weather differently.  And they look different when new.

Hi;

 Now for spmething like that it depends . If the plaque is old and the copper has turned blackish from acid rain then do this . Paint the base with a thinned mixture of Anthracite and copper then clear flat coat it .

  Come back with a wash of soot black and clear semi-gloss . That should work for the base Or you can do black ( Alclad ) as your base and do a copper wash and clear semi - gloss overcoat .

 Don posted after me , but he is right too .
