I'm coming late to this thread... so excuse me while I catch up.
Why in the world would one want to use this stuff on their $200-$3,000
lens?? To remove scratches???
It's an abrasive for sure. Sounds like it's finer than Jewlers Rouge or
3,000 grit diamond polish (hard to find lately).
But the last time I checked, most folks aren't proficient at
grinding/polishing glass.... plus it's still in the body, so you'll get a
falling off on the polish job at the edges.
And how can one get a lens so deeply scratched that they'd attempt such a
"repair" theirself?? I saw the posts where some people can't touch a
camera unless they play Rugby with it... but your favorite lens??
For a source of lamp black... what's the problem with getting an el-cheapo
kerosene oil lamp & smoke the chimney till ya have enough to do your deed?
(I collect such lamps, & believe me, it don't take but a minute for em to
smoke the glass). Which is why I have the questions.... I've rubbed the
glass chimneys & that (cast) glass don't look a whit better for it.
Does it have to be lamp black?? What about the "old trick" of using
newsprint on your car windows? Granted, it's an old trick because today's
papers don't have much (if any) residual ink on em ... and the fiber
content (rag) is probably so low that's it's akin to your old polyester
pants.
I dunno about some of the stuff I read on here.... usually, I can get by
with a lipstick brush & a good, clean, cotton handkerchief... & maybe the
moisture from my breath (not spit).
