When it comes to finding the right paint for your tow dolly, there are a few things to consider. Firstly, it's important to prepare the surface by removing any rust and old paint. This can be done through sandblasting, wire brushing, or using a flapper wheel. Once the surface is clean, you may want to apply a primer to prevent rust, such as Rust-Oleum's Rusty Metal Primer in red oxide. As for the paint itself, you can choose from a variety of options, including Rustoleum oil-based paint, truck bed liner, or a tough liner coating. Some people also recommend POR 15, especially for rust spots, but it may not hold up well to UV rays without a topcoat.

What You'll Learn
Use Rust-Oleum Rusty Metal Primer
If you're looking to paint your tow dolly, you might want to consider using Rust-Oleum Rusty Metal Primer. This product is designed to stop rust and prevent corrosion on metal surfaces. It can be applied directly to heavily rusted metal, bonding tightly to the rust and creating a surface that paint can adhere to.
To use Rust-Oleum Rusty Metal Primer, start by preparing the surface of your tow dolly. Use a wire brush or sandpaper to remove any loose paint, rust, or debris. If there is existing paint on the dolly, you may need to use a paint stripper or sandblaster to remove it completely. Once the surface is clean and free of debris, you may want to consider using a rust converter or inhibitor to neutralize any remaining rust and prevent future corrosion.
Once the surface is prepared, shake the can of Rust-Oleum Rusty Metal Primer thoroughly to ensure the contents are mixed properly. Hold the can about 10-16 inches away from the surface of the tow dolly and spray in a steady back-and-forth motion, overlapping each stroke slightly to ensure even coverage. Apply several thin coats, allowing the primer to dry between coats.
After the final coat, allow the primer to dry completely, which typically takes about 24 hours. Once it's dry, you can apply a top coat of your chosen paint colour. Make sure the paint is compatible with the primer and follow the manufacturer's instructions for application.
By using Rust-Oleum Rusty Metal Primer, you can transform a rusty tow dolly into a freshly painted piece of equipment, protecting it from further corrosion and giving it a new lease of life.

Sandblast the surface
Sandblasting is a great way to remove rust or old paint from the surface of your tow dolly. It is a low-cost, simple technique that delivers high-quality results.
To sandblast the surface of your tow dolly, you will need to select the right abrasive material and equipment. For rust and paint removal, mineral sands composed of materials like olivine and staurolite are a good option for thick metal pieces. Avoid silica sand due to the health risks associated with inhaling the dust. Instead, consider aluminium oxide grit, which is extremely sharp and perfect for surface treatment, or aluminium silicate (coal slag), a cheap and dispensable option. If you are concerned about damaging the metal, soda blasting uses bicarbonate soda at low pressure to gently remove rust and clean surfaces.
Before beginning the sandblasting process, ensure you are wearing protective gear, including eye protection, gloves, and a respirator. The process can be messy, so it is recommended to work outdoors or in a well-ventilated area. Use a tarp to collect the grit and contain the mess, and keep a safe distance from others to avoid grit travelling to other areas.
When sandblasting, maintain consistent pressure to ensure effectiveness and avoid damaging the surface. Start with a low setting and gradually increase the pressure until it is strong enough to remove the paint or rust without causing harm to the metal. Select a shorter hose to maximize pressure, and keep the compressor close to the sandblaster to prevent air pressure loss. Choose a nozzle with a narrow opening of about 3⁄8 inch (9.5 mm) for a concentrated stream of abrasive.
For small jobs, such as sandblasting a tow dolly, a cabinet blaster is a perfect option. This type of blaster is small and enclosed, with built-in gloves and a nozzle, allowing you to see and control the process more easily. Sandblasting is a great DIY option for removing paint and rust from your tow dolly, but always exercise caution and prioritize safety when working with this equipment.

Apply a topcoat
Once you have found the right paint for your tow dolly, you can apply a topcoat to ensure a durable finish. Here is a step-by-step guide on how to apply a topcoat to your tow dolly:
Prepare the Surface:
Before applying the topcoat, it is essential to prepare the surface of your tow dolly. Start by removing any loose paint, dirt, or debris using a flapper wheel or sandblasting. If there is rust on the surface, use a rust-eliminating primer or a rust converter to treat the affected areas. Ensure the surface is clean and free of any contaminants. You can use a power washer or pressure washer for this step, but make sure the surface is completely dry before moving on to the next step.
Sand the Primer:
If you have applied a primer or a previous coat of paint, it is recommended to lightly sand the surface with fine-grit sandpaper (around 200-grit). This process will create a rough surface for the topcoat to adhere to and ensure a stronger bond. Use a palm sander with 80-grit sandpaper to rough up the primer or previous paint coat.
Choose the Right Topcoat:
Select a topcoat that is compatible with the primer or paint you have used. It should be a durable and hard-wearing topcoat designed for metal surfaces. Choose a colour that matches your desired aesthetic. You can opt for a clear coat or a coloured topcoat, depending on your preference.
Apply the Topcoat:
Follow the instructions on your chosen topcoat product for application guidelines. Typically, you can use a spray gun, a roller, or a brush to apply the topcoat. Ensure the application method provides even and thorough coverage. Apply thin coats to avoid dripping or sagging. Allow each coat to dry according to the manufacturer's instructions before applying subsequent coats.
Cure and Inspection:
Allow the topcoat to cure completely according to the manufacturer's recommendations. This may involve leaving the tow dolly in a controlled environment for a specified period. Once cured, inspect the finish for any imperfections or areas that may require touch-ups. Ensure that the topcoat is smooth and consistent across the surface of the tow dolly.
Applying a topcoat to your tow dolly will not only enhance its appearance but also provide protection against the elements and corrosion. Remember to follow safety guidelines when working with paints and coatings, including wearing protective gear and ensuring adequate ventilation.

Use a spray gun
If you want to use a spray gun to paint your tow dolly, there are a few steps you should follow to ensure a smooth and durable finish. Firstly, it's important to prepare the surface of the dolly by removing any rust or old paint. You can use a wire brush, sandblasting, or a flapper wheel to get rid of any loose rust or paint chips. Once the surface is clean and smooth, you may want to apply a primer, such as Rust-Oleum's Rusty Metal Primer in red oxide, to prevent further rust and create a base for the paint to adhere to.
After the primer has dried, you can set up your spray gun. If you don't already own one, you can purchase a cheap spray gun from a store like Walmart or TSC for around $20. Connect your spray gun to an air compressor and thin your chosen paint to the viscosity recommended by the manufacturer. Test the spray gun on a scrap piece of material to ensure the paint is spraying evenly and that you are comfortable with the application process.
When you're ready, start spraying the tow dolly with smooth, even strokes. Ensure you maintain a consistent distance from the surface and overlap each stroke slightly to avoid uneven coverage. Take your time and work in sections to avoid drips or runs. Once you've covered the entire surface, allow the paint to dry thoroughly.
If you're looking for a durable finish, consider applying a clear coat or a bed liner after the paint has dried. This will add an extra layer of protection and help your paint job last longer. With the right preparation and application techniques, using a spray gun can be an effective way to paint your tow dolly and achieve a professional-looking finish.

Power wash the dolly
Power washing your dolly is an important step before painting it. Here is a detailed, step-by-step guide on how to effectively power wash your tow dolly:
Firstly, ensure you have gathered the necessary tools and equipment for power washing. You will, of course, need a power washer, as well as safety gear such as gloves and eye protection. It is also recommended to have a scraper, a brush, and a flapper wheel to hand.
Begin by clearing the area around the dolly, ensuring you have enough space to work comfortably. Cover any nearby objects or surfaces that you do not want to get wet. Once you are satisfied with the setup, start by using the flapper wheel to remove any surface rust and loose or chipping paint. This process is important to ensure the new paint will adhere properly to the surface.
After removing the rust and old paint, it is time to apply a cleaning solution to the dolly. Choose a degreaser or a specialised power washer detergent to ensure the surface is thoroughly cleaned. Follow the instructions on your chosen product for dilution rates and application methods. Once the cleaning solution has been applied, use the power washer to rinse it away, adjusting the pressure and nozzle as needed to effectively remove all dirt, grease, and residue.
For any stubborn areas or tough stains, use a brush or scraper to agitate the cleaning solution and loosen the debris before rinsing again with the power washer. Once you have thoroughly rinsed the dolly, inspect it closely to ensure all dirt and contaminants have been removed. If necessary, repeat the process, especially if dealing with heavy soiling or extensive rusting.
Finally, once you are satisfied with the results, switch off the power washer and put down any tools. Carefully inspect the dolly one last time to ensure no spots have been missed, and then allow it to air dry completely before proceeding with the next steps of your project, such as applying a primer or the new paint.
