Cleaning the tank: Sandblast the tank to ensure it's paint-ready

Sandblasting is an effective method for removing paint and ensuring that the surface is ready for repainting. It involves the high-speed projection of abrasive materials, propelled by compressed air or water, to strip paint from a surface. This technique not only removes paint but also creates a rough surface that enhances the adhesion of the new paint.

To sandblast your 1950s Evinrude fuel tank, you should first consider your level of experience with sandblasting. Sandblasting can be dangerous, and it is recommended to hire a local sandblasting specialist if you lack the necessary skills and equipment. If you choose to proceed, ensure that you have the appropriate personal protective equipment (PPE), including a respirator, face shield, protective clothing, gloves, and work boots. The work area should be adequately ventilated to disperse dust and fumes, and containment materials such as tarps should be used to prevent the spread of abrasive media and paint particles.

The next step is to choose the appropriate abrasive media for your project. Common options include aluminum oxide, glass beads, crushed glass, steel grit, ceramic grit, copper slag, walnut shells, and more. The choice of abrasive depends on the surface type and the type of paint or coating you need to remove. Additionally, you will need an air compressor to generate the compressed air required for the process.

Once you have gathered the necessary equipment and ensured your safety, you can begin the sandblasting process. Carefully follow the instructions for your chosen equipment, ensuring that you maintain a safe distance from the work area and taking precautions to avoid any potential ricochets. The sandblasting process will strip away the paint and any other coatings or contaminants, leaving your 1950s Evinrude fuel tank with a clean and roughened surface that is ready for repainting.

After sandblasting, it is important to properly clean and prepare the surface for the new paint application. This may involve removing any remaining dust or debris and ensuring that the surface is dry before applying a primer or the new coat of paint. By following these steps and taking the necessary safety precautions, you can effectively use sandblasting to clean and prepare your 1950s Evinrude fuel tank for a fresh coat of paint.

Paint options: Choose from automotive base/clear or engine enamel

When it comes to painting old 1950s Evinrude fuel tanks, there are two main paint options to choose from: automotive base/clear or engine enamel. Both options have their own advantages and considerations, which should be taken into account before starting your project.

Automotive base/clear coat finishes have become a popular choice for painting projects. This finish is created by applying a base coat of paint, followed by a clear coat. The clear coat is what gives the paint its shine and protection. One of the benefits of using a base/clear coat system is that it is generally easier to achieve a great shine compared to enamel finishes. The normal process involves wet sanding and buffing, which makes the final result less dependent on the skill of the painter. Base/clear coat finishes are also known for their durability and resistance to UV rays, which can cause discolouration and fading over time.

On the other hand, engine enamel is a tough and durable option once it has fully cured. Enamel finishes have been traditionally used for painting projects, but they do have some drawbacks. Enamel paint is more susceptible to UV damage, which can cause the paint to lose its shine and discolour. Additionally, enamel finishes may require more preparation and skill to achieve a smooth and glossy finish.

It is worth noting that no paint will adhere well unless the surface is thoroughly cleaned and prepared. Sandblasting or sanding can help create a smooth surface for the paint to adhere to.

For fuel tanks, it is important to use a paint that is fuel-proof. Both automotive base/clear and engine enamel options can provide fuel resistance, but it is crucial to choose a product specifically designed for this purpose.

Ultimately, the decision between automotive base/clear and engine enamel depends on your personal preference, the desired finish, and the level of protection needed for your fuel tank.

Colour: Evinrude tanks were painted in Gas Tank Red or off-white

When it comes to restoring old 1950s Evinrude fuel tanks, one of the key considerations is colour. Evinrude tanks from the 1950s were typically painted in one of two colours: Gas Tank Red or off-white.

For the years 1949 to 1958, the designated colour was Gas Tank Red. However, there may be slight variations in the shade of red used during this period. Some sources suggest that the red colour could lean towards orange, with one person noting that their tank from this period appeared to be more orange than the typical Gas Tank Red. This colour was known as Cavalier Red and was used for several years. Therefore, when restoring a tank from this era, it is important to determine the exact shade of red that was originally used.

In 1959, Evinrude transitioned to a different colour, which was still referred to as Gas Tank Red but had a noticeably different hue. This change in colour may have been a result of the transition to a different paint type, as some sources suggest that the tanks from 1959 onwards were painted with automotive base/clear or engine enamel. These paints are fuel-proof, ensuring that the paint job remains durable and long-lasting.

The off-white colour was also an option for the 1959 tanks, providing a neutral alternative to the red shade. It is worth noting that achieving an accurate colour match for these vintage tanks can be challenging, and it may require careful examination of the original paint or consultation with experts to determine the precise shade required.

When repainting an old Evinrude fuel tank, it is essential to ensure that the tank is thoroughly cleaned and prepared. Sandblasting can be an effective method to remove old paint and create a smooth surface for the new paint to adhere to. Additionally, it is crucial to use a fuel-proof paint to ensure the longevity of the paint job and to prevent any issues with fuel leakage.

Application: Use epoxy primer and urethane enamel for a tough coating

When it comes to refurbishing old fuel tanks, the application process and choice of paint are crucial for a durable and aesthetically pleasing outcome. Here are some detailed instructions for applying epoxy primer and urethane enamel to create a robust coating on your 1950s Evinrude fuel tanks:

Surface Preparation:

Before applying any paint, ensure the surface of your fuel tank is thoroughly cleaned and prepared. Any residual fuel, grease, or dirt will hinder paint adhesion. Consider using a degreaser to remove contaminants, and if there is significant rust or old paint, sandblasting or sanding may be necessary to create a smooth, even surface for the new coating.

Primer Application:

Start by applying an epoxy primer, which will serve as the base coat for your project. Epoxy primers are known for their excellent adhesion and corrosion resistance. Before application, ensure the primer is well mixed, and if necessary, thin it with a suitable solvent as per the manufacturer's instructions. You can apply the primer using a brush, roller, or spray, depending on the size and shape of your fuel tank. Always work in a well-ventilated area and wear the appropriate personal protective equipment, including a respirator. Allow the primer to cure completely according to the manufacturer's guidelines before proceeding to the next step.

Urethane Enamel Topcoat:

Once the epoxy primer is cured, you can apply the urethane enamel topcoat. Urethane enamels are known for their toughness and durability. Again, ensure the paint is properly mixed and thinned if necessary. Apply the topcoat using your chosen application method, maintaining a consistent and smooth technique. Multiple thin coats are generally better than a single thick coat, allowing the recommended curing time between each application.

Final Curing and Inspection:

After applying the final coat of urethane enamel, allow it to cure completely. Curing times can vary depending on environmental conditions, so it's crucial to refer to the manufacturer's instructions. Once cured, inspect the coating for any imperfections, ensuring there are no runs, sags, or areas of inadequate coverage. If necessary, apply additional touch-ups and allow them to cure.

Maintenance and Care:

Your newly coated fuel tank will require some care to maintain its appearance and functionality. Avoid exposing the tank to harsh chemicals or physical damage. Regularly inspect the coating for any signs of wear, tear, or corrosion. With proper maintenance, your Evinrude fuel tanks should maintain their coating for an extended period.

Alternatives: Consider powder coating or a new poly tank

If you're looking to restore old fuel tanks, there are a few alternatives to traditional painting that can give your project a fresh look. Powder coating and investing in a new poly tank are two options to consider.

Powder coating is a popular alternative to painting that can give your fuel tank a unique and durable finish. This process involves applying a dry powder, typically a type of resin or polymer, to the surface of the tank and then curing it with heat. Powder coating can create a wide range of finishes, from textured to high-gloss, and can be more cost-effective than a custom paint job. It is also known for its toughness and resistance to stone chips. However, it may not be suitable for all tanks, especially if they contain plastic or lead filler, as these materials cannot withstand the high temperatures required for curing. Additionally, powder coating may not provide the same level of gloss or depth as a top-quality paint job.

When considering powder coating, it's important to be aware of its limitations. Some users have reported issues with the powder coating softening or turning gooey when exposed to gasoline, lacquer thinner, or brake fluid. It is also important to ensure that your tank is properly prepared and free of any solder or filler materials that could be affected by the heat during the curing process.

Another alternative to consider is investing in a new poly tank. Poly tanks are relatively inexpensive and eliminate the chance of particles entering your fuel system, which can occur with older steel tanks. This option may be particularly appealing if you're looking for a more straightforward solution that doesn't involve the time and effort of refinishing your old fuel tank.

Ultimately, the decision between powder coating, investing in a new poly tank, or traditional painting depends on your specific needs, preferences, and budget. Each option has its own advantages and considerations, so it's important to weigh them carefully before making a choice.
