A tank sealer kit saves a rusty fuel tank for a fraction of replacement cost. But which kit? Here's how to choose.
Match the kit to tank size
Kits are sized by tank capacity. Undersizing means you won't fully coat the inside; oversizing wastes product. Measure your tank's litres and pick accordingly.
Match it to rust level
- Light rust: a standard clean + de-rust + seal kit is plenty.
- Heavy rust/scale: choose a kit with a stronger de-rust stage, and budget extra flushing time.
Follow the full process
Whichever kit you pick, the method matters — see our step-by-step fuel tank sealing guide.
