Anyone knows what this blob of orange fluid is? It looks thick and viscous, almost like secretion from some insect.
About 3 -- 4 years ago, I was painting the jack posts in our basement and noticed that a few of them had these fluid droplets surrounded by rust (just like in the picture below) on the surface. I cleaned them up and used the Rust-Oleum Rusty Metal Primer before painting. In a year or so, these began to reappear and now many of the posts have them. The fluid seems to dissolve the paint and cause the steel to rust.
