Easily detect vibration or tampering—this paint becomes brittle once dried and cracks from movement. Originally used in the aerospace industry, this paint won’t corrode and adheres to most surfaces, including all types of metal. It’s useful on screws, nuts, and bolts in assemblies with high vibration, such as gearboxes or conveyor lines. Or use it to check for vibration between mated parts, such as pipe fittings and pipe, by applying it directly to both parts.

To speed up drying and curing time, blow hot air on the paint or place the item you’re painting in a warm environment.
