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.
- Frame tubes, gussets and engine mounting lugs
- Swingarms, centre stands and side stands
- Bracketry, subframes and rack mounts
- Steel mudguards and chain guards behind failing paint
- Steel fuel tank exteriors, once emptied and made safe
- Fastener heads and captive nuts you are not replacing
Step-by-step on this job
- 01
Dismantle as far as is sensible
Loose parts on a bench get a far better finish than parts treated in situ, and you can see all sides.
- 02
Brush and feather
Wire brush the scale, feather back the edges of failing paint until nothing lifts.
- 03
Degrease every surface
Chain fling and engine oil are everywhere on a bike. Degrease, rinse, dry.
- 04
Thin coats on tubing
Round tube shows every run. Keep the coat thin and rotate the part as it sets.
- 05
Topcoat and reassemble
Satin or gloss frame enamel after 24 hours. Refit with new fasteners where the old ones are pitted.

What not to do
The cautions that save a re-do.
- Never on chrome, polished aluminium, or spoked rims you want to keep bright
- Nothing near brake discs, pads, calipers or the drive chain
- Empty and vent a fuel tank properly before any work — vapour is the hazard
- Bearing races, threads and slider surfaces must stay bare

Frequently asked questions
Can I use it inside a fuel tank?
No. Tank interiors need a dedicated fuel-resistant sealer system, and the vapour risk makes DIY work genuinely dangerous.
Will it restore rusted chrome?
No. Pitted chrome needs re-plating. The converter only addresses the steel underneath.
Is it strong enough for a frame?
As a converter-primer under a proper frame enamel, yes. For a show-standard finish, powder coating over bare blasted steel is still the benchmark.
What about rusted spokes?
Individual spokes are easier to replace than to coat well, and a coated spoke never looks right.
