There are several types of quarter panels that serve different purposes and that also depend on the material. Each of these panels is meant for the different needs of automobile owners and manufacturers alike.
Direct Bolt-On Replacement Panels
This is as far as the factory-designed and the direct bolt-on replacement panels go. These panels are manufactured to match the factory specifications on all the cars they are used. They come fitted with holes, brackets, and bolts or welds to allow for easy installation. It is almost like the original design and structural integrity in as much as the car looks upon modification.
Weld-On Panels
These panels are referred to as permanent quarters since they are welded into place with several welding points. These are preferred by those who seek durability. This type of quarter panel is often required in high-end racing cars or vehicles in extreme conditions as they provide much sturdier car structure reinforcement.
Skin Panels
These panels are partial quarters made to cover damage sections. They are also known as quarter panel skins because they are made to fit over existing panels. Skin panels are less expensive and such ideal for minor body repair. These can also be used when one is not interested in replacing at the underlining skeleton of the car.
Outer Panels
These are the panels that one will primarily see on the exterior of a car. They provide the car with protection, and even if a car were to be stripped down, it would still look complete from the outside. The exterior panels can be independent of other body parts like the roof or doors.
Inner Panels
These panels are not easily seen from the outside as they are located inside the car. They provide reinforcement and support to exterior panels. Inner panels are often used in conjunction with outer panels.
Different Material Panels
Quarter panels can be fabricated from the following auspiciously diverse materials, which also contain distinct advantages: Steel, Aluminum, and Fiberglass. Steel panels are strong and easily repairable compared to aluminum, which is lightweight and resistant to rust. This is not only lightweight but also can be stretch molded to fit complex shapes. This feature of fiberglass makes it very suitable for specialized quarter panels for unique cars.
Goodness gracious, a quarter panel for a car can be chosen depending on the type of car and personal preferences. Several factors need to be considered in as the choosing entails consideration.
Type of Car
The car owner's make and model will hold a huge impact on what kind of quarter panel they will need. Quarter panels are specific to each vehicle. This means that one cannot fit a panel from another model, no matter how tempting it seems. Often, manufacturers or sellers have a list of compatible parts based on the car's VIN.
Material Quality
Prioritize materials that are rust-resistant, especially if the vehicle is commonly used in areas with corrosive conditions, like salt on the roads. Steel panels can be coated with galvanization or zinc to retard rust. Aluminum comes naturally resistant to rust. This makes it more ideal in regions where the vehicles are constantly exposed to moisture. Poor quality materials will warp over time and will require constant replacement.
OEM vs. Aftermarket
OEM panels are made by the car manufacturer or a certified by the car manufacturer company. These come with the guarantee that the part will fit perfectly. Aftermarket panels can be produced by other manufacturers. Well, there are cowboys among farmers, and so is it for aftermarket panels. Some aftermarket panels may be of better quality than what the factory offers.
Durability and Strength
Check if the panel is strong enough to withstand impacts and other stressful activities like drag racing, off-roading, or rugged usage. Aluminum panels are going to bend, while fiberglass panels can crack under impact. Steel or high-quality metal panels will serve are more durable.
Pay Attention to The Finish
The finishing of the quarter panel is more than aesthetics; it influences rust resistance. Select finishes that complement the car's paintwork and provide a uniform outlook. Finishes like primer or painted topcoats commonly featured on replacement panels protect the material from environmental damage.
Cost Considerations
Generally, OEM parts are more expensive than aftermarket. Sometimes aftermarket panels can be costly if they are high-end. Additionally, it is not uncommon for cheaper materials to translate to greater expenses in the long run due to rust-out or physical damage. This is why the car owner needs to balance the cost and the quality of the part he wants to purchase.
Replacing a quarter panel is going to be a significant undertaking. Extensive knowledge of auto mechanics can come in handy as this procedure involves removing damaged parts and replacing them with new ones.
Assess the Damage
Carry out a physical check on the quarter panel to define how far the damage goes. If the bend needs pulling or a new panel is needed is usually dependent on the assessment. Aside from the panel, other parts like mounting brackets and bolts may require replacement.
Gather Required Tools
In as much as it's a DIY, gathering the required tools makes the process a lot easier and faster, includes the basic tools like the basics such as screwdrivers and spanners, wheels and jack stands, and a suspension wrench, as well as specialized tools such as a weld or rivet gun, and a quarter panel alignment tool.
Remove Old Panel
Loosen bolts and screws holding the current quarter panel; gently pry it off using a flathead screwdriver or a panel removal tool. Be cautious to not damage surrounding car parts as one is removing the old panel.
Fit New Panel
Position the new quarter panel and align it with pre-drilled holes and with other car body parts. Don't bolt everything yet; do a mock fitting to ensure it fits perfectly and that the body lines are consistent.
Secure The Panel
Using a rivet or weld gun, secure the panel to the car's frame; if using rivets, follow with washers and screws; if welding, ensure to grind down welds for a smooth finish. Be careful and follow the manufacturer’s instruction. This secures the panel to the car.
Priming and Painting
After securing the new panel, apply primer and paint to blend the new part with the car’s outlook. This step protects against rust and makes the panel visually indistinguishable from the rest of the car's body.
Reassembly
Put back all parts and components removed during the process, and ensure all screws and bolts are properly tightened, and reinstalled interior parts boasting of their removal for panel replacement.
Quality Checks and Visual Inspections
These will help identify rust, dents, and weak areas that may have gone unnoticed before. These should happen at least every month or more often if the car is used in harsh conditions.
Cleaning
It is worth noting that regular cleaning will remove dirt, salt, and debris that can cause rust or damage to a quarter panel. This is more advisable after exposure to wet or salty conditions, as cleaning should be often done with water and car-safe detergent to avoid rust with a focus on seams and joints.
Waxing
Waxing forms a protective layer on the paint that repels water and contaminants. It is advisable to do this after the cleaning process. Waxing can also help maintain the finish and protect the panel from UV damage.
Repairs
Small dents or scratches can be repaired immediately to avoid further complicating things. Dents can be fixed using a hairdryer and cold water method or can be taken to a body shop. Scratches should be touched up with paint to avoid rust. Also, consider repairing quarter panels immediately after noticing any damage.
Check for Loose or Missing Hardware
It is important to check for loose bolts, screws, or rivets and, if any, do re-tightening. Missing hardware will be replaced promptly. This also helps reinforce the panel and prevent rattling or misalignment.
Repainting and Resurfacing
Consider resurfacing an aging paint job to help address wear and tear on the panel. A professional could also repaint to get a new appearance and also avoid rust and damage to the structure in general.
Protection From Damage
Parking away from heavy traffic or under tree shades will avoid falling branches, debris, or door dings. For those who desire extra protection, consider affixing clear bra wraps. It will ward off scratches and chips without hindering visibility.
Regular Maintenance on Other Car Components
Since the quarter panel is part of the overall car structure, it is good practice to regularly maintain other car components as it also helps with the general health of the panel. This includes looking at parts like the suspension, tire conditions, and frequent brake checks.
A1: Apart from protecting the trunk and rear area of a car, a quarter panel adds to a vehicle's structural integrity. It contributes to an automobile's overall skeletal framework and thus offers resistance to bending and twisting when driving. The panel reinforces the car and improves alignment on the wheels, doors, and other body parts.
A2: During a routine visual inspection of the car, look out for rust, visible holes, extensive dents, or peeling paint. Besides such signs, check the structural integrity of the car. Once this is compromised, the car's framework is going to be affected, making it difficult for some mechanical parts to function properly. Interior problems like water leaks, mold build-up, and inconsistent gaps between body parts can also indicate the need for a replacement.
A3: It is possible to replace a quarter panel at home if sufficient knowledge and the right tools are available. DIYs can work out well for small repairs requiring skin panels. Complex procedures that require welding or riveting and working on structural components of a vehicle are best left to professionals.
A4: This is a big no! Fiberglass and steel are two distinct materials that cannot chemically bond through welding. They can, however, be bonded together using adhesives like epoxy resin or by mechanical fastening.
A5: Regular cleaning and waxing will go a long way to protect one’s car quarter panels. Conduct periodic quality checks and visual inspections and take care of any minor scratches or damages immediately after noticing them. Also, consider parking away from heavy traffic or under shade of trees to avoid falling branches, debris, or door dings.
