Am I doing Something dangerous to my health by grinding this unknown substance off? Anyone know what it most likely could be?
I bought A used steel topped table this week. 3x5’ and 1.5” thick top.
It was pretty rusty. I began Wire brushing it off and that revealed a black “paint” like enamel surface over the bare metal top.
This “paint” would not grind off or wire brush off very well. (3 hours of wire brushing and it’s still there)
flap discs didn’t work either as they “clogged” up with this black stuff and it would stop sanding immediately.
I tried Muriatic acid as well. Full strength for a couple hours and it removed some of the black paint but just a dent into it.
I’ll try to attach pictures I took.
