Rusty Metal Primer vs Rust Reformer: What’s the Difference?

Rust is a common problem for metal surfaces, and Rusty metal primer vs Rust Reformer are two products designed to fix this.

Rusty Metal Primer vs Rust Reformer

Rusty metal primer has been around longer than Rust reformer, and some people believe that it’s better at protecting against rust.

But is Rusty Metal Primer always the best choice.

We will explore Rusty Metal Primer vs Rust Reformer in this article to help you decide which product is right for your needs.

Rusty Metal Primer vs Rust Reformer | Know The Basic Difference Between Them

Rusty Metal Primer

Rusty Metal Primer is a two-component product that comes in liquid form. Rusty metal primer must be applied to bare steel before the paint or other coating is applied, which means you need to remove any existing coatings first.

Rusty Metal Primer

Rusty Metal Priming will also require annual maintenance with a Rusty Metal Reformer – because of it’s effectiveness at preventing rust and its ease of application, some people believe this type better than others on the market today (such as Rust Reformers).

Rust Reformer

Rusty Reformers are applied with a brush or roller and can be used on surfaces that already have coatings, though you’ll need to remove any loose paint.

Rust Reformer

Rusty reformer is an expensive but easy-to-apply product that requires annual maintenance as well as regular surface treatments.

The best part about using the rusty reformer over other products like metal priming is there’s no poisonous fumes!

Details Comparison of Rust Reformer vs Rusty Metal Primer

Rusty metal primer and Rust Reformer are two products that can be used to protect an object from corrosion.

Rusty metal primer relies on a protective layer, while the reformer is designed for fast-acting application in extreme cases where there is little time left before rust has spread to other areas of the surface area.

The reformer creates a coating around any exposed surfaces which will keep them safe against potential future damage by using oils made up of aliphatic hydrocarbons or solvents like xylene with light naphtha cleaning solutions.

However, this product may not work well if you have long-term exposure problems due to its inability to penetrate into layers below what it covers; thus leaving your item more vulnerable than when applying just Rusty metal primer.

Rusty metal primers have a thicker consistency than reformers and may not work as quickly in smaller areas, but can penetrate below the surface to protect from future damage.

Rusty Metal Primer is specially designed to provide protection against rusting or oxidation when used as a base coat before painting.

Rust Reformer works best as a topcoat following paint application either water-based or oil-based paints alike and has been tested by many different manufacturing professionals in diverse situations.

Which to Choose:

Deciding whether Rust reformed or Rusty Metal Primed depends largely on what your needs are for how long you want protection against rust and under what conditions your surface will be exposed to water (in high humidity areas) or moisture (indoors).

If Rusty Metal Primer is used as a base coat, it’s water-resistant and has the ability to increase the adhesion of other coats on top.

Rusty Metal Primer can also be applied over wet surfaces which makes this product ideal for many situations including painting metal furniture or stainless steel appliances like refrigerators.

Rust Reformer provides an extra layer of protection against rusting with its zinc phosphate corrosion inhibitor that protects metals from oxidation when exposed to air moisture.

Rust reformed should not be used in high humidity areas such as basements because it will only corrode quicker than Rusty Metal Primed paint does without any added benefit since Rusty Metal primer already resists both corrosive environments well enough by itself.

Rusty Metal Primer is more resilient and durable than Rusty Metal Reformed so it’s a better option for outdoor use.

Rusty metal primer is also available in gloss, semi-gloss or flat options while Rusty metal reformed only comes in one type of finish which means the user must choose between durability vs protection against rusting if they need both qualities at once.

Rusty metal reformed does not require an additional sealing coat as Rusty Metal Primer will sometimes do when painting over bare metal surfaces like copper pots or silverware because Rusty Metal Reformers zinc phosphate corrosion inhibitor provides that extra layer of protection already.

Rusty Metal Reformers zinc phosphate corrosion inhibitor is also an anti-corrosion primer which Rusty metal Primer isn’t.

Rusty metal reformers zinc phosphate corrosion inhibitor works on all types of metals, including steel, iron, and cast aluminum while Rusty Metal Primer only protects against rusting so it’s a good option for any type of metal but not as versatile.

There are two different ways that Rusty Metal Primer can be applied either by spraying or brushing the surface to be painted with Rusty Metal Primer followed up by a second coat when dry OR using Rusty Metal Reformer (which has both resins in it) directly over rusty surfaces before painting them.

This will give you more protection from rust than just applying Rusty Metal Primer. Rusty Metal Primer must be applied over a clean surface, and Rusty metal Reformer can also be used as an undercoat for Rusty Metal Primer or any other primer.

Rusty metal reformers can also be sanded so you don’t need to worry about taking off the paint with it but Rusty Metal Primer should not be sanded because it will remove too much of the coating Rusty Metal Reformers are cheaper than Rusty metal primers.

Work by either spraying or brushing on rusty surfaces followed up by another coat when dry OR use Rusty metal re-former (which has both resins in it) directly over rust before painting.

This gives more protection that just applying a single layer of Rusty Metal Primer.

It is also worth noting Rusty Metal Primer is more of a metal primer with Rusty metal Reformer being also an undercoat.

Rusty Metals should not be sanded because it will remove too much paint while Rusty Metal Reformers can have the top layer removed for ease of painting.

Spray or brush Rusty Metal primers onto your surface and then apply another coat when dry OR use Rusty metal reformer directly as an undercoat, which gives better protection than just applying one layer of Rusty Metal Primer.

It’s also worth mentioning that Rusty metals need to avoid getting sand so they don’t lose their coating; Rusty metals are best left untouched aside from spraying or brushing on some rusty surfaces followed up by another coat when dry OR use Rust re-former directly as an undercoat.
