Rust Grip® has been tested against 1,500 different chemicals and is only unsuitable for continuous immersion in ammonia and urea derivates.
Rust Grip® works by penetrating through and coating over the rust to it against further expansion. Rust converters work by chemically changing the rust into a benign form which only lasts for 3 months and must be overcoated.
Practice standard safety precautions when working with Rust Grip®, including protective clothing. Rust Grip® will adhere to and cure on skin. Rust Grip® is USDA-approved (with original 1992 approval letter) and safe, but it will wear on skin for several weeks before being sloughed off with normal skin renewal.
Because Rust Grip® works rapidly, do not leave a container open to the air for longer than 4 hours, or Rust Grip® will draw in the ambient humidity and begin to cure. Use caution when resealing the container, as any Rust Grip® on the seal track of the lid or container may cause the two surfaces to seal. A brush or roller used to apply Rust Grip® cannot be cleaned.
As long as it is immediately cleaned after it is applied, Rust Grip® can be removed with xylene or MEK. There is no way to remove Rust Grip® when it has set. Brushes and rollers must be thrown away. Flush spray machine, hoses and gun with solvents to clean out. When breaking for lunch, seal off Rust Grip® container, run solvent through the machine and hoses and leave gun submerged in solvent pail.
