Restoring a rusty fuel tank: methods by budget

4 methods by budget

1. White vinegar (5€) — surface rust only
2. Phosphoric acid (15-25€) — moderate rust, needs neutralization
3. Electrolysis with car charger (30-50€) — best for deep rust, no metal damage
4. Resin coating kit (50-100€) — for leaking or heavily pitted tanks
