Permatex Bolt Mark - Tamper Proof Indicator

Permatex's new Bolt Mark™ is a convenient visual method for identification of vibratory loosening or tampering in nuts, bolts, fasteners, and assemblies. This tamper-proof torque seal provides warranty protection against tampering. Marks will be easily broken if parts are tampered with or become loose and is highly visible under ambient light and fluorescent under UV light.

What retailers will carry this...orange and yellow are a must.

Great idea....

Is it oil resistant though? Was thinking about using this for cam bearing bolts, wanted to make sure it wouldn’t just erode over time.

How about a clear version? I want to use this on used items I sell because I had scams pulled when the buyer takes a part out and switches it with his damaged part and I receive a broken item in return.

Merely making a face and tossing the nail polish into the trash doesn’t explain why you think it’s bad.
