1985 Buick Riviera Bumper Filler: Repair & Replacement

Hey guys! Ever find yourself staring at your classic 1985 Buick Riviera, admiring its lines, and then bam! – your eyes land on those cracked, faded, or even missing bumper fillers? Yeah, it's a bummer. Those fillers, also known as bumper extensions, are crucial for maintaining the car's aesthetic and original design. Over time, they become brittle due to exposure to the elements, leading to unsightly cracks or complete disintegration. But don't worry; you can definitely tackle this issue and bring your Riviera back to its former glory. This guide will walk you through everything you need to know about those pesky 1985 Buick Riviera bumper fillers, from understanding their purpose to repairing or replacing them.

Understanding 1985 Buick Riviera Bumper Fillers

Alright, let's dive into what these bumper fillers actually are. These aren't just random pieces of plastic; they're specifically designed to bridge the gap between the bumpers and the car's body. Back in the day, manufacturers used these fillers to create a seamless, integrated appearance. For the 1985 Buick Riviera, these fillers are essential to maintain its sleek, streamlined look. Without them, you're left with awkward gaps that detract from the car's overall design. The original fillers were typically made from a flexible type of plastic or rubber compound that could withstand minor impacts and weather exposure. However, time isn't kind to these materials. Constant exposure to sunlight, temperature changes, and road debris leads to degradation. You'll start noticing cracks, discoloration, and eventually, the filler might just crumble away. Beyond aesthetics, bumper fillers also serve a practical purpose. They help protect the car's body from minor bumps and scrapes. While they're not designed to withstand major collisions, they can absorb some impact, preventing damage to the more expensive parts of your car. So, keeping them in good condition isn't just about looks; it's also about protecting your investment. Whether you're a seasoned car enthusiast or just starting to get into classic car restoration, understanding the importance of these often-overlooked components is key to keeping your 1985 Buick Riviera looking its best. Plus, replacing or repairing them can significantly increase the car's value, especially if you ever plan to sell it. Trust me; a Riviera with intact bumper fillers stands out from the crowd!

Assessing the Damage

Okay, before you start grabbing tools and ordering parts, let's take a good, hard look at the condition of your bumper fillers. A proper assessment will save you time, money, and a whole lot of frustration. First, give your fillers a visual inspection. Look for any obvious signs of damage: Cracks, no matter how small, are a telltale sign of wear and tear. Even hairline cracks can worsen over time, so it's best to address them early. Check for discoloration. Years of sun exposure can cause the fillers to fade or turn yellow. This not only looks bad but also indicates that the material is breaking down. See if any pieces are missing. Sometimes, chunks of the filler can break off completely, leaving unsightly gaps. Feel the fillers. Are they brittle or flexible? If they feel hard and prone to cracking, they're likely past their prime. Gently push on them to see if they crumble or flex. Also, check the mounting points. These are the areas where the filler attaches to the bumper and the car's body. Make sure these points are still intact and not rusted or broken. If the mounting points are damaged, you'll need to address them during the repair or replacement process. Once you've completed your inspection, you can decide on the best course of action. Minor cracks and discoloration might be repairable, while extensive damage or missing pieces will likely require replacement. Remember to take pictures of the damage before you start any work. These photos can be helpful when ordering parts or seeking advice from other Riviera enthusiasts. Don't underestimate the importance of this step. A thorough assessment will guide you in making informed decisions and ensure that you get the right parts and materials for the job. So, grab your flashlight, get up close and personal with those bumper fillers, and let's get started!

Repairing vs. Replacing: Which Way to Go?

Now that you've assessed the damage, the big question is: should you repair or replace your 1985 Buick Riviera's bumper fillers? Both options have their pros and cons, so let's break it down to help you make the best decision. Repairing bumper fillers is a viable option if the damage is minor. Think small cracks, surface imperfections, or slight discoloration. Repairing typically involves using a plastic repair compound or filler to fill in the cracks and then sanding and painting to match the original color. This can be a cost-effective solution, especially if you're on a budget. However, keep in mind that repairs may not last as long as a full replacement, especially if the underlying material is already brittle. Also, achieving a perfect color match can be tricky, so you might end up with a noticeable difference in appearance. Replacing bumper fillers is the way to go if the damage is extensive. This includes large cracks, missing pieces, or significant deterioration of the material. While replacement is generally more expensive than repair, it offers several advantages. You get a brand-new filler that is free from any existing damage, ensuring a long-lasting solution. Replacement fillers are also made from modern materials that are more resistant to cracking and fading than the original ones. Plus, you can be confident that the color will match perfectly, restoring your Riviera's original appearance. Ultimately, the decision depends on your budget, your skill level, and the extent of the damage. If you're comfortable with DIY repairs and the damage is minimal, repairing might be a good option. But if you want the best possible result and don't mind spending a bit more, replacement is the way to go. Remember to weigh the pros and cons of each option carefully before making your decision. And if you're unsure, don't hesitate to seek advice from a professional auto body shop or other Riviera enthusiasts. They can provide valuable insights and help you choose the right path for your restoration project.

Start with a medium-grit sandpaper and finish with a fine-grit sandpaper. Be careful not to sand too much, as you could damage the surrounding area. Mask off the surrounding area. Use masking tape and paper to protect the areas you don't want to paint. Apply primer. Apply several thin coats of primer to the repaired area, allowing each coat to dry completely before applying the next. This will help the paint adhere properly and create a smooth, even finish. Paint the repaired area. Apply several thin coats of paint to the repaired area, matching the color to your car's original paint. Allow each coat to dry completely before applying the next.

Step-by-Step Replacement Guide

So, you've decided that replacing your 1985 Buick Riviera's bumper fillers is the best way to go? Great choice! While it might seem a bit daunting, it's totally manageable with the right tools and a little patience. Let’s break down the process step-by-step. First and foremost, safety comes first: Wear safety glasses and gloves to protect yourself from any sharp edges or debris. Ensure your car is parked on a level surface and the parking brake is engaged. Gather your tools and materials. You'll need a socket set, a wrench set, a screwdriver set, new bumper fillers (make sure they're the correct ones for your model year), and possibly some penetrating oil. Locate the mounting points. These are the screws or bolts that hold the bumper fillers in place. They're usually located on the inside of the bumper and along the edges of the filler. Apply penetrating oil. If the screws or bolts are rusty or difficult to remove, spray them with penetrating oil and let it soak for a few minutes. This will help loosen them up. Remove the old bumper fillers. Use the appropriate socket, wrench, or screwdriver to remove the screws or bolts holding the old bumper fillers in place. Be careful not to strip the screws or damage the surrounding areas. Gently pull the old bumper fillers away from the car. If they're stuck, use a plastic pry tool to help loosen them. Clean the mounting surfaces. Use a clean cloth to remove any dirt, rust, or debris from the mounting surfaces. This will ensure a good fit for the new bumper fillers. Install the new bumper fillers. Align the new bumper fillers with the mounting points and push them into place. Make sure they fit snugly and are properly aligned. Secure the new bumper fillers. Use the screws or bolts you removed earlier to secure the new bumper fillers in place. Tighten them snugly, but be careful not to overtighten them, as this could damage the fillers or the mounting points. Double-check the installation. Make sure the new bumper fillers are securely attached and properly aligned. Stand back and admire your work! You've successfully replaced your 1985 Buick Riviera bumper fillers. Your car looks like new again! Now, take a step back and admire your handiwork. You've not only improved the look of your Riviera but also protected it from further damage.

Painting and Finishing Touches

So, you've either repaired or replaced your 1985 Buick Riviera's bumper fillers. Awesome! But to really make them blend seamlessly with the rest of your car, you'll likely need to paint and finish them properly. Getting the paint job right is crucial for achieving a professional look. First, you'll need to prepare the surface. Whether you've repaired or replaced the fillers, start by sanding them down with fine-grit sandpaper. This will create a smooth surface for the primer to adhere to. Be sure to remove any dust or debris with a tack cloth. Next, apply a few coats of primer. Primer helps the paint adhere better and provides a uniform base color. Use a high-quality automotive primer and apply it in thin, even coats. Allow each coat to dry completely before applying the next. Once the primer is dry, it's time to paint. Use automotive paint that matches your car's original color code. You can find this code on a sticker inside the driver's side door or in the engine compartment. Apply the paint in thin, even coats, using a spray gun or aerosol can. Hold the nozzle about 10-12 inches away from the surface and move it in a smooth, steady motion. Allow each coat to dry completely before applying the next. After the paint is dry, you can apply a clear coat. Clear coat protects the paint from scratches and UV damage and gives it a glossy finish. Apply the clear coat in the same way as the paint, using thin, even coats. Once the clear coat is dry, you can buff and polish the surface to remove any imperfections and create a smooth, glass-like finish. Use a polishing compound and a buffing pad to gently buff the surface, then use a clean cloth to wipe away any residue. Finally, stand back and admire your work. You've transformed your bumper fillers from drab to fab, and your 1985 Buick Riviera looks better than ever! Remember, patience and attention to detail are key to achieving a professional-looking paint job. Take your time, follow the steps carefully, and you'll be amazed at the results.
