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.
Where rust shows up first
The areas worth checking before you order.
- Main rails, crossmembers and drawbar
- Deck edges, wheel wells and mudguard mounts
- Loading ramps, hinges and locking pins
- Coupling, jockey wheel clamp and safety chain mounts
- Tie-down rails, D-rings and stake pockets
- Spring hangers, U-bolts and axle tubes
Step-by-step on this job
- 01
Strip the deck if it is timber
Rust always hides under deck boards. Lifting them turns a cosmetic job into a proper one.
- 02
Wash, scrape, dry
Detergent wash, scraper on the scale, then a dry day before you open a bottle.
- 03
Convert the frame
Follow every weld line. Angle iron holds water in its inner corner — that corner needs the most attention.
- 04
Treat fasteners and pins separately
Brush around U-bolts and spring hangers, but leave threads and locking faces clean.
- 05
Topcoat, then refit
After 24 hours, chassis enamel over the lot, then put the deck back down.
What not to do
The cautions that save a re-do.
- Keep it clear of brake drums, cables and bearing hubs
- Check the drawbar and coupling for thinning — those are safety-critical
- Do not coat the locking faces of ramp pins and latches
- Electrical plug and light wiring should be masked

Frequently asked questions
Can I treat a galvanised trailer frame?
Yes, on the areas where red rust is showing through failed galvanising. Sound galvanising does not need it.
Do I need to remove the wheels?
Not for the frame, but mask the hubs. For spring hanger work, taking a wheel off makes it much easier.
How often should I re-treat?
Inspect annually. Touch up any chips in the topcoat before rust restarts and you may never need a full re-treat.
Will it work on a rusted mesh deck?
Yes, and mesh is where a brush beats a spray comfortably — you can wet both sides of each strand.
