What Materials Can I Use Rust Blocker On?

There are many materials where a rust blocker can prove effective. A rust blocker keeps your property in good condition by preventing rust and metal corrosion. Options like the Magica rust blocker are ideal for treating and preventing rust in ferrous metals. You can use it on trailers, fences, autos and even farm equipment to ensure peak condition and consistent performance. Stainless steel, aluminum or galvanized steel are materials you cannot use a rust blocker on. Here is everything to know about rust blockers and how to use them for maximum efficiency.

How Do Metal Primers Work?

Primers are the critical elements of a surface, the undercoat present before it gets painted with a topcoat. Manufacturers apply primers after removing all the external elements on its surface for better adherence to the surface’s paint. New and exposed materials require more primers than already coated surfaces to create a seal and guarantee extra protection to the paint structure.

A primer creates a bonding platform for standard paint to stick to the material better. The low adhesion build of metal surfaces makes it challenging for the paint to dry and stick perfectly to metal surfaces. Adding a primer creates a binding layer that allows a smooth and even topcoat paint application on even stainless steel.

The rust-inhibiting properties of a primer is one consideration observed by most consumers. These qualities involve how well the layer created can prevent rust on the applied surfaces. You can find the best metal primer for your topcoat by evaluating the ingredients used or reaching out to the appropriate technical support team before any purchase.

On Which Surfaces Can You Use Metal Primers?

Metal primers can be used on metal cladding, copper, lead, iron, galvanized stainless steel, aluminum and other materials. If you are wondering, "What materials should I put rust inhibitor on?", this section has your answer.

You can use metal primers on:

  • Tower blocks
  • Offshore refineries
  • Lift doors
  • Tools
  • Mining equipment
  • Breweries
  • Shutter doors
  • Vehicles
  • Pipes and drainage systems

How to Use Rust Blockers on Gears and Tools


The first step to using rust blockers on gears and tools is to apply them. You’ll have to spray, immerse or wipe the rust block formula on your unit’s surface evenly. Most products feature an aerosol or trigger spray to facilitate the application and reach tight areas.

Let It Dry

You will have to give the rust blocker formula some time to dry out after applying it. It dries at a similar rate to water and leaves a thin and invisible film that prevents rust for more than a year.


Rinsing is necessary when you decide to paint, oil or prime the surface. To remove the blocker coating, you can rinse the unit’s surface with warm water.

Rust blockers are not as effective on some materials as they are on others. So, what can you use rust blocker on? This article answers all your questions on what materials you can use your rust blocker on and which to avoid. You should reach out to Magica Inc. for more information.
