Question about using pencil to mark metal plant tags
I read on one of the website's where I ordered zinc plant tags that you can write on them with a #2 pencil and it will last outside in the weather for several years.
Seems too good to be true! I'm wondering, before I go ahead and do this with all five hundred tags, if anyone has tested this method.
If so, did it last for several years with out needing to be touched up or will it fade away with direct sunlight exposure?
