1. Identify the Cause:
Before you start repairing, you need to understand *why* the paint is peeling. Common causes include:
* Poor Preparation: The original paint job wasn't properly prepared (surface not clean, rust not removed, primer not applied correctly).
* Rust: Underlying rust is the biggest culprit. Paint can't adhere to rust.
* Moisture: Water trapped under the paint (e.g., from a leak or poor sealing) will cause blistering and peeling.
* Sun Damage: UV rays can weaken the paint over time.
* Low-Quality Paint: Cheap or inappropriate paint will be more prone to peeling.
* Improper Application: Incorrect application techniques (too thick coats, not enough drying time between coats) can lead to problems.
2. Repairing the Peeling Paint:
The repair process depends on the severity:
* Minor Peeling: If only small areas are affected, you might be able to:
* Clean the Area: Thoroughly clean the affected area with soap and water, then degrease with a wax and grease remover. Let it dry completely.
* Scrape Loose Paint: Gently scrape away any loose or flaking paint with a plastic scraper or putty knife. Avoid damaging the remaining paint.
* Sand Smooth: Lightly sand the area with fine-grit sandpaper (e.g., 220-grit) to create a smooth surface.
* Prime: Apply a suitable automotive primer to the bare metal (if any is exposed). Let it dry completely.
* Paint: Apply touch-up paint that matches your van's color. Apply several thin coats, allowing each coat to dry thoroughly.
* Clear Coat (Optional): For protection, a clear coat is recommended.
* Extensive Peeling: If large areas are affected, especially if rust is involved, a more extensive repair is necessary:
* Rust Removal: This is crucial. Remove all rust using a wire brush, sandpaper, or a rust converter. If the rust is deep, you might need to replace the affected metal panel.
* Body Filler (Optional): If there are significant imperfections after rust removal, use automotive body filler to smooth out the surface. Sand smooth after it's cured.
* Primer: Apply several coats of automotive primer, allowing each to dry completely.
* Sanding: Sand the primed area smooth with progressively finer grits of sandpaper.
* Paint: Apply several thin coats of automotive paint that matches your van's color.
* Clear Coat: A clear coat is highly recommended for protection and durability.
3. Preventing Future Peeling:
* Regular Washing and Waxing: Keep your van clean to prevent dirt and grime from damaging the paint. Waxing provides a layer of protection against UV rays and environmental contaminants.
* Address Rust Immediately: Deal with any rust as soon as you notice it. Rust spreads quickly and will undermine the paint.
* Proper Paint Application: If you're repainting, ensure you follow the manufacturer's instructions carefully. Proper surface preparation and application techniques are vital.
When to Seek Professional Help:
If you're uncomfortable with any of the repair steps, or if the damage is extensive, it's best to take your van to a professional auto body shop. They have the tools, experience, and expertise to handle complex repairs properly. A poorly done repair will only lead to more problems down the line.
