Question 1

would this work on a nickel/copper mixed metal?

Accepted Answer

This is for solder and lead... look for a formulation for copper for the best results.

Question 2

Is this a true deep black or more of a very dark silver?

Accepted Answer

I wouldn't say it's a true deep black, just makes the lead blend-in with old weathered lead (kindof super dark grey, nearly black). FYI: have an old historic home and I can't really tell the difference between the new lead and the rest of my 100+yr old lead in my front windows. However, unfortunately, if you look closely, the new lead piece between the glass (or center of the "I" beam cross-section) is still bright silver since I didn't think to coat the center of the lead strip before installing. Anyhow, if you use this and don't want the lead to look bright silver anywhere, I would suggest coating the inner strip before installing, and then re-coating the outside after it is installed...

Question 3

Any tips for using it on brass?  I have tried and it looks great at first but when it dries, it looks like the brass is rusting underneath

Accepted Answer

I haven't used it on brass, I bought it to finish a stain glass repair but after playing with it (rubbing it in every surface I found in my garage) I found out that gives an aged patina to zinc plated finishes, like those common shiny bolts you get at the hardware store. I'm sorry I can't help you with your question.

Question 4

Will this stain my bathtub after rinsing the stained glass?

Accepted Answer

Should not the overall bathtub, but any metal parts it will.  I would suggest rinsing out side.
