Metal gutters, downpipes and fences are exposed to the weather every day, which can lead to fading, peeling and rust. The White Knight Rust Guard® system makes it simple to restore and protect metal so it looks great and lasts. Follow these easy steps.
Step 1: Clean the Surface
A clean surface helps your paint stick and prevents peeling.
- Wipe down with Rust Guard Solvent to remove grease and contaminants
- If previously painted, scrape or sand off any loose paint and surface rust
Step 2: Treat Rust
If you find rust, stop it before painting.
- Use Rust Guard Rust Converter to chemically treat rust and create a stable black barrier ready for primer
- For hard-to-reach areas like joints and crevices, apply Rust Guard Fish Oil, which penetrates rust scale and leaves a protective coating
Step 3: Prime the Metal
Priming gives your topcoat maximum adhesion and corrosion resistance. Choose the right primer for your surface:
- Rust Guard Metal Primer – for steel, wrought iron and ferrous metals.
- Rust Guard SLS Etch Primer – designed for aluminium, galvanised iron, brass and copper, and ideal for gutters, pipes and gates. Apply 1 even coat and let it dry as directed.
Step 4: Apply a Topcoat
The topcoat provides colour and long-lasting protection.
- Rust Guard Advanced Enamel – a quick drying topcoat with outstanding rust protection and a professional finish, backed by an 8-year guarantee
- Rust Guard Epoxy Enamel – a rust-inhibiting enamel that transforms lightly rusted surfaces in one easy step
For most gutters, pipes and fences, Advanced Enamel is the ideal choice. Apply 2 coats, allowing drying time between each
Step 5: Protect Special Surfaces (Optional)
If you’re working with bare aluminium, brass or copper fittings:
- Finish with Rust Guard Clear Guard, a protective clear coating that seals the surface and prevents tarnishing
Handy DIY Tips
- Stir all products thoroughly before use.
- Lightly sand smooth or glossy surfaces before priming.
- Apply 2 coats of primer (if required) and 2 coats of topcoat for the best results
- Always follow the drying times on the pack.
With White Knight Rust Guard®, painting metal is straightforward: Clean → Treat → Prime → Paint. In just a weekend, you can refresh gutters, pipes or fences with a durable finish that’s built to last.
