In this article, I'll guide you through the meticulous process of detailing your MGB GT for shows up and down the country, sharing my insights and expertise to ensure that your classic beauty shines as it deserves.

I. Understanding the MGB GT's Unique Appeal

The MGB GT's distinct blend of sportiness and refinement has captured the hearts of countless enthusiasts for decades. Its sleek lines, iconic "B" badge, and distinctive chrome accents create a visual symphony that transports us back to an era of classic motoring. The beloved MGB is not just a car; it's an experience, a connection to the past, and a testament to automotive craftsmanship.

II. Importance of Detailing for Car Events

Participating in shows presents a unique opportunity to showcase your MGB GT. These events are a celebration of automotive history and culture, and your meticulously detailed car will undoubtedly catch the eyes of fellow enthusiasts and judges. Detailing is not just about aesthetics; it's about respecting the legacy of your MGB GT and letting its story shine through.

III. Pre-Detailing Preparation

Before embarking on the detailing journey, it's essential to prepare your MGB thoroughly. Take a walk around your car, inspecting it for any blemishes or imperfections. Addressing these issues beforehand will prevent them from detracting from your car's overall presentation. Gather your detailing supplies, which should include quality car wash solutions, microfiber towels, clay bars, polishing compounds, and wax.

IV. Step-by-Step Detailing Guide

A. Exterior Detailing

1. Washing and Decontamination

Begin with a gentle wash to remove surface dirt and grime. Use a dedicated car wash solution and follow the two-bucket method to minimise scratches. Your MGB’s paint deserves nothing but the gentlest care. If you encounter stubborn contaminants, a clay bar can help restore smoothness.

2. Paint Correction

This step requires finesse and patience. Inspect your paint under different lighting to identify swirl marks, scratches, and imperfections. Use a polishing compound and a dual-action polisher to carefully remove these marks, revealing the true depth of your paint's colour.

3. Polishing and Waxing

Polishing brings out the gloss and vibrancy of your MGB GT's paint. Choose a high-quality polishing compound and work in sections for the best results. Once your paint is flawless, apply wax to protect it from environmental elements and enhance its shine. Waxing also provides an additional layer of depth to your car's appearance.

B. Interior Detailing

1. Cleaning and Vacuuming

The interior of your MGB GT deserves as much attention as the exterior. Begin by removing floor mats and vacuuming the carpets and seats. Use a soft brush attachment to gently remove dust from intricate areas.

2. Leather and Upholstery Care

For leather seats and upholstery, select a pH-balanced leather cleaner. Clean the surfaces gently using a microfiber cloth and a soft-bristle brush. Follow up with a high-quality leather conditioner to keep the leather supple and prevent cracking. We always recommend cleaning and treating your leather twice a year, best when the clocks change. This method ensures a treatment prior to the season and a treatment prior to being prepared for wintering.

V. Engine Bay and Underside Detailing

The engine bay and undercarriage are often overlooked, but these areas contribute to the overall presentation of your MGB GT.

A. Engine Bay

Cover sensitive components and use a dedicated engine bay cleaner to remove grease and grime. Gently scrub surfaces and rinse thoroughly, taking care to avoid electrical components. Once dry, apply a specialised engine dressing.

B. Undercarriage

Spray the underside with a suitable cleaner to remove road grime and dirt. Use a brush or pressure washer to reach hidden areas. Dry thoroughly to prevent rust, and consider applying a protective underside coating for added longevity.

VI. Wheels, Tires, and Glass

A. Wheels and Tires

Your MGB GT's wheels and tires contribute to its overall aesthetic. Use a dedicated wheel cleaner to remove brake dust and grime. Apply tire dressing to the sidewalls for a deep black finish. Polish the wheels to a mirror-like shine, ensuring they complement the car's appearance.


B. Glass

Clean and streak-free glass enhances your MGB GT's overall presentation. Use a glass cleaner and microfiber towels to eliminate fingerprints and smudges. Clean both the inside and outside of the windows for crystal-clear visibility.

VII. Final Touches and Presentation

Before the big day, inspect your car for any remaining imperfections. Address them diligently, and then focus on the final touches:

  • Apply tire dressing for a uniform look.
  • Restore trim pieces using appropriate products.
  • Ensure your car is parked in a well-lit area, allowing the sunlight to highlight its refined lines.
VIII. Maintaining the Detailed Look

Preserving your cars show-ready appearance requires ongoing care:

  • Regularly wash your car using proper techniques and products.
  • Apply a fresh coat of wax every few months to maintain paint protection.
  • Address any scratches or imperfections promptly to prevent them from worsening.
