Painting over rusted surfaces and using a so-called encapsulant is a recipe for long-term failure. As the adage goes, if I don’t see it, it’s OK! It’s a common misconception that simply painting over rust or using a ‘rust encapsulant” will solve corrosion problems.

Here is an example of corrosion that occurred in a spring after utilizing a similar product to cover up the corroded springs. Never apply paint over a corroded part if it is a key structural component. It takes proper preparation and constant maintenance to ensure corrosion will not destroy your components. In the case of rust, what you don’t see can hurt you. Preparation and consistent maintenance are essential to prevent corrosion from destroying components. Selecting the correct grade of steel alloy for the application can mitigate corrosion risks. 

Stainless steel’s corrosion resistance is primarily due to its chromium-nickel content, which forms a passive oxide layer on the surface. However, the specific characteristics of stainless steel, including its strength, ductility, and resistance to various forms of corrosion (such as pitting, crevice corrosion, and stress corrosion cracking), vary significantly across its numerous grades and families.
