Should You Spiff Up the Interior of a Used Car?

Want to get top dollar when you sell your car? Dealers know that spiffing up the interior of a used car is the best way to command a higher price. Whether you're planning to sell your vehicle or just want to freshen up your daily driver, we'll show you how to slap the shabby off your vehicle's interior. It's neither hard nor expensive, and you'll be amazed at just how new your car's interior will look. This guide will walk you through the process, offering expert advice and practical steps to transform your car's cabin.

Rejuvenate Your Car’s Interior!

You can recondition the plastic/vinyl on your doors, dash, seats, and console areas, or do it all, including the carpet, velour, and upholstery. You can recolour just about everything in the interior. If you vacuum and shampoo your vehicle ahead of time, you can complete the whole rejuvenation process in a single weekend, allowing for drying time between steps. This comprehensive approach ensures that every surface receives the attention it deserves, leading to a truly revitalised space.

Meet the Expert

Larry Trexler, the National Trainer and Technical Service Manager for SEM Products, brings 27 years of hands-on experience in the auto body repair and restoration business. His insights are invaluable for anyone looking to restore their car's interior. The following are Larry’s auto interior repair tips, designed to empower you with professional techniques.

Get the Right Materials and Prep the Vehicle

Using the correct products is crucial for achieving a professional finish. While several companies manufacture reconditioning products, SEM is the brand favoured by most professional shops. It's also readily available at many auto parts stores and online retailers like vinylpro.com and tcpglobal.com. SEM offers a comprehensive range of products designed to repair and refurbish plastic, vinyl, velour, leather, and carpet. When applied correctly, their flexible coloured coatings are known for their durability, resisting chipping, flaking, and fading.

It Makes a Big Difference

The impact of a clean and well-maintained interior cannot be overstated. A refreshed cabin not only enhances your driving experience but also significantly boosts the resale value of your vehicle. Potential buyers are often swayed by the interior's condition, as it reflects the overall care the car has received. Investing a weekend in rejuvenation can yield substantial returns, whether financial or personal enjoyment.

Matching Your Colours

Achieving a seamless look requires careful colour matching. SEM provides refinishing products in over 50 colours. It's recommended to obtain a colour chart from a local dealer and meticulously match colour chips to your car’s existing carpet and plastic parts. This process is specifically designed for restoration, not for changing the interior colour scheme. The best results are achieved by selecting colours that are as close as possible to the original factory shades. This attention to detail ensures that the rejuvenated areas blend in naturally with the rest of the interior.

Materials Required

To undertake this interior transformation, you'll need a selection of specialised products and tools. Here's a breakdown of essential items:

• SEM Interior Refinishing Products: Choose from their extensive range for plastic, vinyl, carpet, and velour. Ensure you have the correct colour matches.
• SEM Cleaner/Prep Solvent: A crucial step for preparing surfaces, ensuring proper adhesion of the refinishing products.
• Applicators: This includes spray guns for larger areas, aerosol cans for smaller touch-ups, and foam applicators or brushes for precise work.
• Masking Tape and Paper: High-quality automotive masking tape is essential for protecting areas you don't want to refinish.
• Vacuum Cleaner: A powerful vacuum with various attachments is needed for thorough cleaning of carpets and upholstery.
• Carpet and Upholstery Cleaner: For deep cleaning of fabric surfaces.
• Soft Brushes: For agitating cleaning solutions and applying products to textured surfaces.
• Microfibre Cloths: For wiping down surfaces and removing excess product.
• Safety Equipment: Gloves, eye protection, and a respirator or mask are vital when working with chemicals and during spraying.

Step-by-Step Reconditioning Process

Follow these steps to achieve a professional interior restoration:

1. Thorough Cleaning:

Begin by thoroughly vacuuming the entire interior, paying close attention to crevices, under seats, and floor mats. Next, use a dedicated carpet and upholstery cleaner to shampoo the fabrics. Agitate the cleaner with a soft brush and then extract the moisture with a wet/dry vacuum or by blotting with clean cloths. Allow the interior to dry completely.

2. Surface Preparation:

This is arguably the most critical step. Clean all plastic, vinyl, and leather surfaces that you intend to refinish using SEM's Cleaner/Prep Solvent. This removes oils, greases, and contaminants, ensuring the refinishing product adheres properly. For textured plastics or vinyl, you might need to use a slightly stiffer brush to work the cleaner into the grain.

3. Masking:

Carefully mask off any areas that will not be refinished. This includes windows, chrome trim, painted surfaces, and electronic components. Use high-quality automotive masking tape and paper to ensure clean lines and prevent overspray.

4. Colour Application:

If using SEM's aerosol products, ensure the can is at the correct temperature (usually room temperature) and shake it vigorously for the time recommended on the can. Apply the colour in thin, even coats. It's better to apply multiple light coats rather than one heavy coat to avoid runs and sags. Allow adequate drying time between coats as per the product instructions. For spray gun application, follow the manufacturer's guidelines for pressure and nozzle settings.

5. Refinishing Different Materials:

Plastic and Vinyl: Apply colour in light coats, allowing each to flash off before the next. SEM products are designed to be flexible and adhere well to these surfaces.

Carpet and Velour: For fabric surfaces, SEM offers specialised products. These are typically applied in light mist coats to avoid saturating the fibres, which could lead to stiffness. The goal is to lightly colour the fibres without making the carpet feel wet or heavy.

6. Drying and Curing:

Allow ample drying time for all refinished surfaces. While the surfaces may feel dry to the touch relatively quickly, the curing process can take longer. Refer to the product data sheets for specific drying and curing times. Avoid heavy use or cleaning of the interior until the products have fully cured to ensure maximum durability.

7. Final Inspection and Reassembly:

Once everything is dry and cured, carefully remove the masking tape and paper. Inspect the refinished areas for any imperfections. If necessary, minor touch-ups can be made. Reassemble any removed components, such as door panels or seats, if you removed them for easier access.

Tips for a Professional Finish

• Work in a Well-Ventilated Area: This is crucial for your health and for achieving a smooth finish.
• Test in an Inconspicuous Area: Before applying to visible surfaces, test the product and colour on a hidden spot to ensure you're happy with the result.
• Maintain Consistent Distance: When spraying, keep the can or spray gun at a consistent distance from the surface to ensure even coverage.
• Use Multiple Thin Coats: This is the golden rule of spray application. It prevents runs and allows for better adhesion and a more uniform colour.
• Patience is Key: Rushing the drying or curing process will compromise the final result.

Common Interior Issues and Solutions

Here's a look at some common interior problems and how the reconditioning process can address them:

Frequently Asked Questions

Q1: Can I change the colour of my car's interior using these products?

While SEM products are excellent for restoring original colours and covering minor variations, they are not designed for a complete colour change. The best results are achieved by matching the original colours as closely as possible.

Q2: How long do these refinishing products last?

When applied correctly to properly prepared surfaces, SEM refinishing products are very durable and can last for many years. Factors like UV exposure and harsh cleaning methods can affect longevity.

Q3: Do I need special tools to apply SEM products?

SEM offers products in aerosol cans for ease of use, suitable for DIY applications. For larger areas or a more professional finish, a spray gun can be used, but this requires additional equipment and expertise.

Q4: How do I clean the interior after it has been refinished?

After the products have fully cured, you can clean the interior using mild automotive interior cleaners. Avoid abrasive cleaners or harsh chemicals, as these could damage the refinished surfaces.

Q5: Is it worth the effort to spiff up a used car's interior?

Absolutely! Whether you are selling the car or keeping it, a clean, fresh, and revitalised interior significantly enhances its appeal and value. The cost and effort are often minimal compared to the rewards.
