FAQs
Can this be used on aluminum?
Yes, it provides good contrast on most metallic surfaces, including aluminum.
Is the blue stain permanent?
It is designed to be highly visible and durable; while it can be removed with solvents, it may leave a residual tint.
How do I remove it from my hands?
Use a grit-based industrial hand cleaner or a shop degreaser followed by soap and water.
Does it dry out quickly?
When the lid is left off, it can dry out; ensure the container is sealed tightly immediately after use.
Is this suitable for outdoor use?
It is intended for workshop environments. Exposure to rain or high humidity may affect its adherence.
Can it be thinned down?
It is formulated for direct use, though compatibility with thinners is not recommended unless suggested by the manufacturer.
Troubleshooting
Marking is too thick or gloppy
Apply less product and ensure it is spread into a very thin, even film for accurate readings.
Product is staining unwanted surfaces
Use a specialized industrial solvent or heavy-duty hand cleaner to remove accidental markings promptly.
Does not adhere to the surface
Thoroughly degrease the steel component; any remaining machine oil will repel the marking blue.

Setup, Compatibility & Care
To ensure optimal performance, clean all surfaces thoroughly with a degreaser before application, as oil or grime will prevent proper adhesion. Apply using a clean lint-free cloth or a small brush for detailed work. For care, keep the container tightly sealed when not in use to prevent the compound from drying out. Store the product in a cool, dry environment away from direct sunlight to maintain the chemical integrity of the dye. If the compound thickens over time, ensure the lid is properly sealed and stored in a temperature-controlled area.
