A few important notes regarding Bleed Through Markers. One, they don’t have to be blue ink. Red, Yellow and Black are also available. The choice usually comes down to which will offset better against the color of the [Rust Inhibitive Steel Primer.](https://www.thesteelsupplyco.com/industrial-coatings/primers-coatings-and-cold-galvanize) Two, bleed through markers will only work with the type of coating they are intended for. Oil based coatings require the standard oil-based bleed through. [Water based primers require a special, water-based bleed through](https://www.thesteelsupplyco.com/blog/bid/85473/bleed-through-blue-markers). If the ![Picture2-2](https://www.thesteelsupplyco.com/hs-fs/hubfs/Picture2-2.jpg?width=200&height=221&name=Picture2-2.jpg)type of ink used is not for the coating it was intended for the piece marks will not bleed through the coatings. The GALVANIZER’S MARKER works in the opposite direction. It will completely dissolve in the acid baths at the beginning of the Hot Dip Galvanizing process. This eliminates any chargebacks from the galvanizer for grinding off the marks and also the possibility the marks remain through the process and bleed through the finished zinc coating. Galvanizer’s markers use an alcohol-based formulas that can dissolve cleanly leaving no trace of the piece marks. For better visibility during fabrication they are available in a![Picture3-1](https://www.thesteelsupplyco.com/hs-fs/hubfs/Picture3-1.jpg?width=212&height=212&name=Picture3-1.jpg) variety of colors: White, Yellow, Green, and Black They are available in a variety of barrel sizes to suit the volume of marks being made.
