I am looking for something with “sharpie”-like behavior in white. It may not exist, just reaching out to see if anyone has a recommendation.
Specifically, to apply to engravings in clear acrylic and glass, that can then be easily removed from the un-marked surface with a rag with a little alcohol. I can get the desired effect with masking and acrylic, but that is not practical due to the shape and size of the items I am working with (and I have a lot of them.)
I had a paint pen but that was not easily removed from the un-marked surface, and it didn’t have the density I need. I ended up using acrylic for that previous project. It’s gone now and I don’t recall the brand.
There are a lot of candidates out there but I don’t want to buy a dozen products to see if they work, so just fishing for suggestions.
