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.
