Funny thing about the dry graphite... My dad and I built a pinewood derby car when I was a kid. We painted it with a brite red paint, it was really painted well. Dad then used the graphite on the wheel axles... It spead, all over the red paint. Making it some sort of metallic color. I think of that every time I hear about graphite...
We also used it for the same! It’s a mess for sure 🤣
