Rusted metal in, paint-ready surface out
Brush RustGuard™ over sound rust, let it cure, then paint. Images are illustrative — results depend on surface condition and preparation.
What you need
Nothing exotic — most of this is already in the shed.
- RustGuard™ Rust Converter (see the calculator below for quantity)
- Wire brush, scraper, and a wire cup brush for a drill on bigger areas
- Detergent or degreaser, a bucket, and clean rags
- Synthetic-bristle brush or short-nap roller, plus masking tape
- Nitrile gloves and eye protection
- Your chosen topcoat, ready for the day after
The method
- 01
1. Remove everything loose
Scrape and wire brush until nothing flakes off under a fingernail. You are not chasing bare steel — you want tightly adhered rust and no lifting paint edges.
- 02
2. Degrease and rinse
Wash with detergent or degreaser, rinse well, and test by splashing water: if it beads instead of sheeting, there is still oil there. Degrease again.
- 03
3. Let it dry completely
Damp pitting or a wet seam will dilute the film and slow the reaction. Give it hours in warm air, longer in a cold garage.
- 04
4. Mask what must stay clean
Good paint, glass, trim, brake surfaces, threads and rubber. Two minutes of tape beats twenty minutes of wiping.
- 05
5. Brush on a thin, even coat
Work it into pitting and seams rather than laying it on thick. The film should look wet and uniform, not puddled.
- 06
6. Watch for the colour change
Rust darkens as it converts, typically within 20 minutes to a couple of hours depending on temperature and humidity.
- 07
7. Second coat on heavy rust
Once the first coat has turned dark and is touch-dry, add a second thin coat to deeply pitted areas.
- 08
8. Cure 24 hours before topcoating
The film needs a full day. Then apply your topcoat within a few days, while the surface is still clean and keyed.

The five mistakes people make
- Applying over grease or wax — the film beads and never bonds
- Laying it on thick, which traps moisture and skins over
- Topcoating too early, which blisters the paint later
- Applying in freezing temperatures or on hot metal in direct sun
- Treating perforated metal and expecting the hole to close

Frequently asked questions
Do I need to sand down to bare metal?
No — that defeats the point. Remove loose material only. The converter needs rust to react with.
What temperature range is safe?
Apply between roughly 10–32 °C / 50–90 °F. Below that the reaction stalls; above that the film dries before it reacts.
Can I use a spray gun?
Yes, through low-pressure equipment suited to water-based coatings. Strain the product and flush the gun with water straight after.
What if it rains before it cures?
Let the area dry, check the film, and re-treat any part that looks washed out or patchy.
