Q) How long will RUST-BLOCK™ last once it is applied?

Q) There are so many types of metal. Will RUST-BLOCK™ work on all kinds?
A) Yes, RUST-BLOCK™ will work with all ferrous and non-ferrous metals. It has been tested on copper and brass and works very well with these metals.

Q) If the steel has a coating, will the coating be damaged by using RUST-BLOCK™?
A) No, RUST-BLOCK™ will not damage any polymers, plastics, or coatings, and can even be used on painted surfaces without damaging most paints.

Q) Are there any conditions that will affect the performance of RUST-BLOCK™?
A) Yes, RUST-BLOCK™ is a water-based rust inhibitor designed for indoor use. If RUST-BLOCK™ is exposed to water, the water will weaken and/or remove the protective coating. Therefore, items treated with RUSTBLOCK™ must be kept away from direct contact with water.

Q) When RUST-BLOCK™ is used as a rust inhibitor, should it be removed prior to treating metal with a coating or paint?
A) Yes, most coatings bond with the metal. Therefore, RUST-BLOCK™ should be removed before any other coatings are applied. We recommend that the RUST-BLOCK™ be rinsed off with water and the parts dried prior to another coating.
