Types of Spray Painting Roof Box

A roof box is a storage container mounted on the roof rack of the vehicle. Its primary purpose is to provide extra storage space when transporting luggage or cargo. A spray painting roof box comes in different types, including:

Hardshell roof boxes

Hardshell roof boxes are designed with durable materials such as ABS plastic. This makes them robust and ideal for long-distance travel. Hardshell boxes also offer great protection from harsh weather conditions. They prevent rain from dripping on the luggage and shield the cargo from strong winds. Besides, hardshell roof boxes have a good aerodynamic shape. They reduce wind resistance and help maintain a vehicle's driving speed. Some hardshell roof boxes have dual opening systems. This allows users to access the cargo from the side or the top.
Softshell roof boxes

Softshell roof boxes are made of robust, weather-resistant synthetic fabrics. They are lighter than hardshell roof boxes. This makes them easier to mount on the roof racks of vehicles. Softshell roof boxes are also more affordable than hardshell roof boxes. They offer a good budget-friendly option for those looking for extra roof space. Although they are designed with materials that can withstand harsh weather conditions, softshell boxes are less effective in bad weather compared to hardshell boxes.
Cargo baskets

Cargo baskets resemble a big wire basket. They are designed with open sides and bottoms, providing easy access to the cargo. Their open design prevents wind resistance. Cargo baskets are ideal for transporting outdoor equipment such as bicycles, kayaks, and camping gear. Since they are open, users might worry about losing their luggage while driving. Therefore, cargo baskets come with optional nets, lids, and tie-down straps to secure the cargo.
Cargo carriers

Roof cargo carriers come as carriers boxes and cargo baskets. They are designed to increase the vehicle's storage space. Roof cargo boxes are watertight and protect the cargo from bad weather. They also reduce wind resistance because of their aerodynamic shape. On the other hand, cargo baskets have an open design. They are mostly used for transporting outdoor equipment. Since they are open, users might worry about losing their luggage while driving. Therefore, cargo baskets come with optional nets, lids, and tie-down straps to secure the cargo.

Specifications and maintenance of spray painting roof boxes

Roof boxes come in different sizes, designs, and materials. Here are some general specifications one can find in a roof box.

Size and capacity

The size of a roof box is an important consideration that will affect capacity. A bigger box will have a bigger capacity. The sizes of roof boxes range from 300-700 liters. A 300-liter roof box is ideal for 1-2 persons. A roof box with a capacity of 500-700 liters is ideal for big families or long journeys. The external dimensions of a roof box are also important because they need to fit the car's roof. The dimensions of a roof box are 120-205 cm in length, 75-90 cm in width, and 40-50 cm in height.
Material

Roof boxes are commonly made from ABS plastic or polycarbonate. ABS plastic is a strong and durable material that is impact-resistant. Polycarbonate is also impact-resistant and very strong. Roof boxes made from polycarbonate are lighter than those made from ABS plastic.
Mounting system

The mounting system of a roof box is important because it should be easy to install on the roof of the car. A roof box can be mounted using a quick mounting system or a dual mounting system. The dual mounting system is more secure and stable compared to the quick mounting system.
Security features

Roof boxes come with security features such as a lock and key to prevent theft and secure valuable items. Some roof boxes have internal straps that secure the contents of the box so they don’t move around.
Aerodynamics

Roof boxes are designed to be aerodynamic and reduce drag when driving. The aerodynamic design helps reduce fuel consumption. Some features that improve aerodynamics include a low-profile shape and a tapered rear design.

It is important to maintain a roof box to prolong its lifespan and ensure it is in good condition. Here are some maintenance tips.

Cleaning: Roof box owners should clean the roof box regularly. Cleaning prevents the accumulation of dirt, road grime, or tree sap that can damage the box. When cleaning, they should use a mild detergent and water. Roof box owners should also clean the inside of the roof box to remove any dirt or debris.
Lubrication: Roof box owners should ensure the mounting hardware is properly lubricated. Proper lubrication reduces friction and prevents wear and tear. They can use a silicone-based lubricant or graphite powder.
Inspection: Roof box owners should inspect their roof boxes regularly. During inspection, they should look for signs of damage, cracks, or fading. They should also inspect the mounting system to ensure it is secure and stable.
Storage: When not in use, roof box owners should store the roof box in a dry and cool place away from sunlight. UV rays from sunlight can cause fading and damage to the roof box.
Replace seals and gaskets: Roof box owners should replace seals and gaskets once they wear out. Worn-out seals and gaskets can cause water leaks and make the roof box damaged.

How to DIY and Replace Spray Painting Roof Box

Here are the steps on how to DIY and replace spray painting roof boxes:

1. First, remove the roof box from the roof rack. This is done by loosening the clamps or fasteners that hold the box in place. Depending on the design of the roof box, this may require a screwdriver, an Allen wrench, or simply hand strength.
2. Clean the roof box thoroughly before painting. This will help ensure that the paint adheres properly to the surface. Use soap and water to remove any dirt, debris, or particles from the roof box. Pay special attention to the areas where the paint will be applied. After cleaning, allow the roof box to dry completely before proceeding to the next step.
3. To mask off the areas of the roof box that need not be painted. Use painter's tape or masking tape to cover these areas. This will help create clean lines and prevent overspray. Ensure that the tape is applied securely and that there are no gaps or overlaps.
4. Use primer spray paint specially designed for plastic or fiberglass surfaces. Hold the spray can approximately 6-12 inches away from the roof box and apply even coats. Start from one end and work your way to the other, overlapping each pass slightly to ensure complete coverage. Allow each coat to dry according to the manufacturer's instructions before applying the next coat. This usually takes a few minutes. Remember to work in a well-ventilated area or use a spray booth to avoid inhaling fumes or getting overspray on surrounding surfaces.
5. After applying the primer, it's time to apply the final coat of paint. Choose a color that suits the style and preference. Shake the spray paint can thoroughly to ensure even mixing of the paint. Apply the paint in the same manner as the primer, using smooth, even strokes. Allow the paint to dry completely before reapplying the roof box.
6. Once the paint is dry, carefully remove the masking tape or painter's tape. Do this slowly and gently to avoid damaging the freshly painted surface. Inspect the painted areas and touch up any imperfections or areas that require additional paint.
7. Finally, reinstall the roof box on the roof rack. Ensure the clamps or fasteners are securely attached and tightened. Double-check that the roof box is properly aligned and positioned according to preferences.
