Until the 1980s, most vehicles were painted using cellulose or two-pack acrylic systems. Though these materials can be sprayed in a single application, they don't offer the long-term protection that modern two-stage systems can provide.
Definition
A two-stage paint repair consists of the application of a base color and, once this has cured, a final coat of clear lacquer to provide gloss and protection. Today most base colors are water-based, though some solvent-based alternatives remain in use.
Clear Coats
Clear lacquers are applied over base colors to give a tough, resilient shine that preserves the integrity of the finished paintwork. They can be applied over solid colors or metallic finishes and are cost-effective because of their short drying times.
Benefits
A two-stage paint repair provides a durable finish that will protect the vehicle's bodywork for years. Clear lacquers don't weather badly in direct sunlight, unlike acrylics, and application is much easier because of short curing times. Two-stage repairs also cope well with adverse weather, but their numerous benefits make the materials more expensive.
