Hi all !

I’d like to repair a little shiny dot( which was caused by hit by camera  I think)on my apo m 50mm body. I have looked through all kinds of way. I finally found Birchwood blackmetal touch up pen and blackmetal finish. Do these products work?  I will greatly apreciated your  answer.
       Kinds regards

I've used the Aluminum Black on a few non-Leica black anodized aluminum lenses with small worn silver spots. The spots turn more dark-grey than pure black, but it makes them blend in quite well. Be sure to follow the instructions closely and rinse off (damp cloth) the areas where you apply it to remove the residue.

I have used a black sharpie and unless the spot is quite large it becomes invisible.

Sharpie works quite well indeed - alas it seems to rub off again rather quickly 🫤

I’ve used this with success… it’s matte black rim touch up paint for fixing curb rash on wheels.

Definitely less is more and better to apply it with the tip of a toothpick than with a regular brush given it’s a tiny application.

The Birchwood product is not a paint, it chemically converts the aluminum surface to a near black color. It's quite permanent.
