Corrosion protection – rust protection with ROSTIO
Rust is a natural but undesirable process that slowly but surely destroys metal surfaces. What begins as a small brown spot can quickly develop into a serious structural problem – whether on a car, trailer, garden fence, tools, or in the cavities of machinery or vehicle bodies. The good news: Rust can be effectively stopped and even prevented – if you work systematically and with the right products.
In this article, we will show you how to achieve professional corrosion protection with ROSTIO products – whether for new paint jobs, restorations, or spot repairs.
1. Preparation: The right way to a rust-free surface
The most important, yet often underestimated, step in corrosion protection is thorough substrate preparation . Even here, crucial mistakes can occur.
❌ Mistake No. 1: Removing rust with a rotating wire brush
Many people resort to a rotating wire brush to remove rust. The result is a deceptively clean, silvery surface . The problem: The wire brush smears rust particles with metallic debris, forming a fine layer that still contains active rust components . This layer prevents subsequent products from adhering properly and is an ideal breeding ground for new rust beneath the paintwork.
✅ Correct: Use CSD discs
Instead, opt for our ROSTIO CSD discs . These special cleaning discs gently remove rust and loose coatings without damaging or smearing the base metal. Ideal for all metallic surfaces, even during restoration and on delicate sheet metal.
2. Remove rust – or convert it directly
Depending on the extent of the rust infestation, different methods are used.
✅ ROSTIO rust remover gel – even for heavy rust
Our ROSTIO Rust Remover Gel isn't just suitable for light flash rust. It also reliably and gently removes heavy rust from iron or steel. The gel adheres even to vertical surfaces and penetrates deep into the rust layer – without running or dripping.

After a short exposure time, the rust visibly dissolves and can be easily brushed or rinsed off. The result: bright, grippy metal – ideal for primers and paints.
✅ ROSTIO rust converter – the practical solution
If complete removal is not possible or desired (e.g. with thin sheet metal, in tight angles or hard-to-reach places), our ROSTIO rust converter offers an excellent alternative.
-
Transforms rust into a stable protective layer
-
No need to wash
-
Ideal for overpainting
-
Thin – penetrates into folds, gaps and cracks
These properties make it the ideal partner for bodywork, fences, metal beams or other components that cannot be completely derusted.

3. Special application: cavities and folds
Rust protection does not end at visible areas – especially cavities , e.g. in vehicle sills, door bottom edges or frame supports, are extremely susceptible to rust.
This is where our special product comes into play: ROSTIO 2in1 cavity sealing with rust conversion .
-
Converts rust AND protects with a layer of wax
-
Can be used directly in wet cavities
-
Actively displaces water
-
Long-term protection through permanent wax preservation
The product is particularly popular with classic car owners and vehicle enthusiasts because it offers long-lasting preservation even in slightly rusty and damp cavities – without any prior drying.
4. Priming: Solid base for every coat
After cleaning or converting the rust, the metal requires a durable protective primer. The quality of this layer significantly determines the service life of the entire corrosion protection system.
✅ ROSTIO Epoxy Primer Spray – Maximum adhesion and protection
Our epoxy primer offers:
-
Excellent corrosion protection
-
Excellent adhesion to steel, zinc, aluminum
-
High resistance to moisture, salt and chemicals
-
Smooth and paintable surface
Ideal for vehicle bodies, trailers, industrial equipment, machine frames, or garden gates. It creates corrosion protection that withstands long-term weathering.

5. Top coat: Protection with rust protection paint
After priming, the protective coating follows. This is where our ROSTIO synthetic resin rust protection paint comes into play.
-
Weatherproof and UV-resistant
-
Shock and scratch resistant
-
High coverage
The synthetic resin paints provide an elastic and durable protective layer. They are ideal for outdoor applications on vehicle parts, railings, containers, or construction machinery. The paint can be applied by brush, roller, or sprayer and ensures an even finish.
