Restoring a classic car to its former glory can be a rewarding experience, but it’s not without its challenges. One common issue classic car owners face is lifting molding. Whether it’s chrome trim, rubber seals, or decorative accents, dealing with lifting molding can be a frustrating but solvable problem. This guide will provide you with a comprehensive understanding of how to fix lifting molding on your classic car, from diagnosing the cause to executing the repair.

Why is My Classic Car Molding Lifting?

Several factors can contribute to lifting molding on a classic car. Age and exposure to the elements are the most common culprits. Over time, the adhesive holding the molding in place can dry out, crack, or lose its grip. Temperature fluctuations, particularly extreme heat or cold, can also accelerate the deterioration of the adhesive. Improper installation during a previous repair can also lead to lifting. In some cases, the molding itself may have become warped or damaged, requiring replacement rather than simply re-attachment. Identifying the root cause is essential for a successful and lasting repair.

Identifying the Type of Molding

Before attempting any repair, you need to determine the type of molding you’re working with. Is it chrome, stainless steel, rubber, or plastic? Each material requires a different approach. Chrome and stainless steel moldings often rely on clips and specialized adhesives, while rubber seals may use a combination of adhesive and friction fit. Plastic moldings can vary widely in their attachment methods.

How to Fix Lifting Chrome Molding on a Classic Car

Lifting chrome molding is a frequent issue. The process involves carefully removing the loose section, cleaning the area thoroughly, and applying a new adhesive.

1. Carefully pry up the loose molding: Use a plastic pry tool to avoid scratching the paint or damaging the molding.
2. Clean the surfaces: Remove any old adhesive residue from both the molding and the car body using a suitable adhesive remover. Ensure the surfaces are clean and dry.
3. Apply new adhesive: Choose an automotive-grade adhesive designed for bonding metal to metal. Apply a thin, even bead of adhesive to the back of the molding or the car body, following the manufacturer’s instructions.
4. Reattach the molding: Firmly press the molding back into place, ensuring proper alignment. Use masking tape to hold it in position while the adhesive cures.

What is the best adhesive for classic car molding?

The best adhesive depends on the type of molding. For chrome and metal, a strong epoxy or specialized automotive trim adhesive is recommended. For rubber, a weatherstrip adhesive is often the best choice.

Repairing Lifting Rubber Seals

Rubber seals require a slightly different approach. Maintaining the flexibility of the rubber is key.

1. Inspect the seal: Check for any tears or damage to the rubber. If the seal is damaged, replacement is usually the best option.
2. Clean the area: Clean the seal and the mating surface on the car body with a suitable cleaner.
3. Apply adhesive: Use a weatherstrip adhesive designed for automotive applications. Apply the adhesive according to the manufacturer’s instructions.
4. Reinstall the seal: Carefully press the seal back into place, ensuring a tight and even fit.

Dealing with Warped or Damaged Molding

Sometimes, the molding itself is the problem. If the molding is warped, cracked, or otherwise damaged, re-attaching it won’t solve the issue. In such cases, replacement is the only viable solution. Sourcing replacement molding for classic cars can sometimes be a challenge, but several specialized suppliers and online resources cater to this market.
