Paint surface Rusting problems

Moisture and chemicals maybe from road salt, sea air or even off road outside parking near where chemicals are used, or damp un ventilated areas undercover, attacking the metal through visible or microscopic breaks in the paint film.

Rusting then often works back under the film, resulting in blistering and peeling. Rusting also forms more rapidly at points where the moisture collects and remains in contact with the film. To Repair remove paint down to metal. Bare metal areas should never be touched by the hands after using metal pretreatment and rust remover and should be primed within 30 minutes to prevent start of new rust formation. Repaint following steps under 'Prevention'.

• Painting over metal which contains rust not completely removed will always result in rapid failure from more rusting.
• Painting over metal touched by bare hands, or metal contaminated by chemical deposits from flatting water.

Prevention
1. Bare metal should be flatted very thoroughly to remove all traces of rust from surface and pits in the metal.
2. Metal should be treated with metal pre treatment and rust remover according to directions.
