A man came into my shop and said he is making "Black Jack" to blacken lead. He says it is made out of carbon and graphite and you apply it with a Q-tip, then let it dry and buff with a brush. I've never felt the need to blacken lead, but I wondered what others think of this.
Darkens zinc and lead came. Following application directions, it polishes
metal to a professional shiny bright dark finish.The wax-like finish protects the
metal surface against oxidation. It will also polish glass leaving a glossy
® Black Jack is not considered a hazardous product.
However, as with all liquid chemicals, care must be taken when handling.

This is the stuff the British like to use after Zebo and Zebrite are no longer made
Traditional wax-based graphite black polish, that gives a brilliant silver-black finish to cast iron. Good for restoring rusty or tired looking fireplaces, grates, BBQ and other cast iron metal. For best results: Apply evenly with a cloth or brush and leave to almost dry before removing excess. Allow to dry fully for a matt black finish. For a Shiny finish simply polish thoroughly once dry with a soft dry cloth or brush. This is a great alternative to zebo polish which is no longer available.
Some lead blacks are much better than others, and some are waxy and truly horrific to work with - just don't expect miracles!
MUCH elbow grease is still required, and, if you buy the wrong lead black, then you will be buffing for hours to get the black wax off your glass surface.
The wrong type also shines the solder and blackens the lead, and you end up with the panel looking 10x worse than you started with.
I don't know this one - I have used ZEBO or ZEBRITE in the past, if I needed to blacken specific areas. I have tried others when Zebo became unavailable, but was shocked at how they performed so badly.
At the end of the day, no lead black and LOTS of elbow grease acheives the best results.
It should only cost a few dollars - try it and see, but I don't think you'll be converted. What I do use it for, regularly, however, is to blacken the putty, to make it the same colour as the lead, mixed with a little whiting.
I wondered if it would be good to blacken putty. I might try it in putty. He also said it works on zinc, so I might try it on zinc. I like lead the way I do it now, I don't think I will try it on lead.
