Now I have the funniest image of a guy scraping the paint on the side of a bus and sniffing it. Hahaha. Mus... Stop sniffing paint!!
Seriously though, what year is this bus that you're sniffing? I have an '82 and while grinding certain surfaces for welding, I noticed a strange, chemical smell and started wondering the same thing, about lead being present. I immediately grabbed my respirator (which I should've been wearing anyway!) to be safe. I imagine it's just thre chemicals within the paint that you're smelling.
