What to know before buying

The listing calls the product water-resistant but also states it is not waterproof. Treat this as a water-resistant, not waterproof, claim.
One hour is listed both as dry time and full cure time. Drying and curing conditions are not provided, so do not assume this timing applies in every environment.

Listing details to confirm

The manufacturer describes application on metal, iron, steel and aluminium and claims compatibility with most automotive finishes and rigid plastics, while the specification table recommends metal. Confirm suitability for the specific surface and follow the product directions before applying.
