Peeling Roof Paint Part Two: Repair

In our last blog we talked about the risks of peeling clear coat and paint, and how you can protect your vehicle from factors that cause damaged paint. If the damage is already done, there are a few repair options, depending on the severity:

1. DIY touch up – suitable for small, localised paint damage
2. Professional respray – suitable for widespread paint damage
3. Clear coat repair – if only the clear coat is peeling but the paint is undamaged
4. Vinyl wrapping

DIY touch up

If you’ve caught it early, you may be able to fix a small area yourself. Make sure that you check your paint code for a perfect colour match.

What you’ll need:

• Sandpaper (400–2000 grit)
• Primer
• Colour-matched spray paint (check your vehicle's paint code)
• Clear coat spray
• Masking tape & newspaper
• Polishing compound

Steps:

1. Sand away loose/flaking paint and smooth the edges.
2. Mask off surrounding areas.
3. Apply primer and let it dry completely.
4. Spray colour coat in light, even layers. Let each layer dry before applying the next.
5. Apply clear coat to seal and protect.
6. Once fully dry, polish to blend with surrounding paint.

Professional respray

If large sections of the roof are peeling, it’s best to consult a body shop.

A full roof respray includes stripping away damaged paint, reapplying primer, base coat, clear coat, and machine polishing for a factory finish. The process tends to cost £250-£500 for a car and £400 - £800 for a van. Some local mobile paint repair services offer cheaper, on-site options, but always check reviews and previous work before booking.

Clear coat repair

You’ll need:

Fine sandpaper (800, 1200, 2000 grit)

• Pre-paint surface cleaner or isopropyl alcohol
• Masking tape and plastic sheeting or newspaper
• Automotive-grade clear coat spray (aerosol can)
• Polishing compound and microfibre cloth

Steps:

1. Clean the area thoroughly.
2. Wash the roof. Use isopropyl alcohol to wipe down the peeling section.
3. Sand the peeling clear coat. Start with 800–1000 grit to remove the peeling edges only. Don’t sand through to the colour coat. Blend the edges gently. Finish with 2000 grit for a smooth surface.
4. Mask off the surrounding area with masking tape and newspaper to protect the rest of the roof and car.
5. Spray 2–3 light, even coats, waiting 10–15 minutes between each. Avoid heavy spraying to prevent drips.
6. Allow at least 24–48 hours (check the can instructions) for the clear coat to harden fully.
7. After curing, lightly wet-sand with 2000 grit if needed, then polish with a compound to restore gloss and blend the finish.

Vinyl wrapping

Vinyl wrapping is a popular alternative. It covers the damage and protects the remaining paint.

Pros:

Vinyl wrapping is heaper than a full respray, can be installed quickly, is reversible, and offers you a customisable look (choose from a range of finishes).

Cons:

On the downside, it only covers the existing damage, it doesn’t repair it, and unlike paint which will last decades if looked after, it only lasts 3-7 years, depending on the quality of the wrap and how it’s looked after. Vinyl wrap costs £150–£400 depending on its size and type.

If you’re unsure about the extent of the damage or want a professional opinion, most local body shops or mobile paint technicians offer free assessments and quotes. For more advice, follow Trust A Garage on Facebook or X.
