Repair any holes, dents or rust spots
Repairing any holes, dents, or rust spots is an essential step before painting your camper. Here's a detailed guide to help you through the process:
Assess the damage:
Start by evaluating the extent of the damage. Look for holes, dents, or rust spots on the camper's body and roof. Pay close attention to common problem areas such as the wheel arches, door sills, windows, and the underside of the camper.
Remove the rust:
To ensure a long-lasting paint job, it's crucial to remove all traces of rust. Use a wire brush, either attached to a drill or handheld, to scrape away loose rust and flaking paint. Be thorough and make sure you work a few centimetres beyond the affected area to ensure no rust is left behind. You can also use rust remover products like Rustins Rust Remover to dissolve any remaining surface rust. Remember to wear protective gear, including gloves and eye protection, during this process.
Repair holes and dents:
For small holes and dents, you can use a body filler or metal epoxy putty to fill and level the affected areas. Work the filler into the hole, ensuring it's flush with the surrounding metal surface. Allow it to dry completely, and then sand it down smoothly. If you're dealing with larger holes, you might need to use a fibreglass repair kit or welding to create a sturdy patch.
Sand and smooth the repaired areas:
Once the filler or epoxy has dried, use sandpaper or a random orbital sander to smooth out the repaired areas. Start with coarse sandpaper (around 80-grit) and gradually move to finer grits (180-220 grit) to create a seamless finish. This step is crucial for achieving a smooth and professional-looking paint job.
Apply a primer:
Before painting, it's a good idea to apply a rust-preventative primer to the repaired areas. This will provide an extra layer of protection against future rust and help the paint adhere better to the surface. Choose a primer suitable for metal surfaces, such as Rust-Oleum Automotive Primer.
Paint the repaired areas:
Use a metal paint that is specifically designed to protect metal surfaces from rust. Apply at least two coats of paint, following the manufacturer's instructions for drying times between coats. Make sure to paint both the top and underside of the repaired areas for maximum protection.
Optional: Apply an underbody sealant:
If the bottom of your camper is in poor condition or you want to provide extra protection, consider using an underbody sealant like Waxoyl or Dinitrol. These products create a thick, durable layer that repels water, salt, and road debris, offering long-lasting protection against rust.
Remember to work in a well-ventilated area and follow all safety precautions when working with chemicals and power tools. Taking your time with these repair steps will ensure a high-quality finish when you paint your camper with aluminium roof paint.

Remove stickers or decals
Removing stickers or decals from your camper is an important step before painting. If you don't want to remove them, you can always paint over them, but this can be a bit trickier and may not give as polished of a final look. Here are some tips to help you remove those stickers and decals:
First, try to peel away the top layer of the sticker. For vinyl or metallic stickers, you may need to use a safety razor blade, the edge of a credit card, or your fingernail to lightly score the top layer and help the removal process.
Next, you can try using a sticker removing agent. Soak a cloth or cotton pad in a removal agent such as vegetable oil, coconut oil, or a store-bought adhesive remover, and apply it to the sticker. Let it soak for a few hours to help loosen the adhesive. You can also use a hairdryer on a medium or warm setting to warm the glue and help release the sticker.
Once the sticker is removed, there may still be some adhesive residue left behind. To remove this, you can use a variety of methods. Try using a damp cloth with warm water and a few drops of dish soap, or a cloth soaked in WD-40 or another water-displacing lubricant. Gently scrape away any remaining adhesive with a plastic razor blade, credit card, or rubber spatula.
If there is still residue remaining, you can try a stronger chemical solvent like acetone or mineral spirits. Soak a cloth in the solvent and hold it against the residue for a few minutes to soften the glue, then wipe it away. For heavy layers of residue, use a safety razor blade to carefully scrape away the glue, being careful not to scratch or gouge the metal.
Finally, clean and dry the metal surface to ensure all residue is removed. You can also buff the surface to restore any shine that may have been affected by the removal process.
With these steps, you should be able to effectively remove stickers and decals from your camper before painting.

Wash the camper with soap and water
To paint your camper with aluminum roof paint, it is important to first thoroughly clean the surface to ensure that the paint will properly adhere. Here is a detailed guide on how to effectively wash your camper with soap and water in preparation for painting:
Before beginning the washing process, gather all the necessary supplies, including a mild soap or detergent, soft sponges or cloths, a water source such as a hose, and some dry towels or a squeegee for drying. It is also recommended to wear protective gear, such as gloves and eye protection, to safeguard against any chemicals or debris.
Start by mixing a mild soap or detergent with warm water. Avoid using harsh or abrasive cleaners, as these can damage the surface of your camper. Fill a bucket with the soapy mixture and use a soft sponge or cloth to apply it to the camper's surface, working in small sections. Gently scrub the entire surface, including the roof, sides, and any other areas you plan to paint. Pay extra attention to areas with dirt, grime, or mildew, ensuring that all contaminants are removed. Rinse each section with clean water immediately after scrubbing to prevent soap residue from drying on the surface.
For hard-to-reach areas, such as tight corners or around fixtures, use smaller sponges or soft-bristled brushes to ensure a thorough clean. Be cautious when cleaning around windows, seals, and vents to avoid causing any damage or allowing water to seep into unwanted areas. If necessary, use a step ladder to safely access higher areas of the camper, being careful to maintain a stable position while cleaning.
After scrubbing and rinsing the entire camper, perform a final rinse to ensure that all soap residue is removed. This step is crucial as any remaining soap can affect the paint's adhesion. Use a clean water source, such as a hose, to thoroughly rinse the entire surface. Pay particular attention to the roof and upper areas, allowing the water to sheet down the sides and carry away any remaining dirt or soap. Ensure that all soap and dirty water are completely removed from the camper's surface.
Finally, use dry towels or a squeegee to remove any remaining water droplets and speed up the drying process. This step helps to prevent water spots or streaks from forming as the camper air-dries. If using towels, opt for microfiber or soft cotton cloths to avoid scratching the surface. Completely dry the camper before proceeding with any sanding or painting steps, as moisture on the surface can impact the effectiveness of these processes.

Sand the aluminium with a fine-grit sandpaper
Sanding aluminium is an essential step to create adhesion between the surface and paint. It is recommended to wear gloves, a respirator, and eye protection during this step as aluminium dust is dangerous for your lungs.
Begin sanding the aluminium with fine-grit sandpaper, around 60 to 80 grit. This will quickly remove old paint and provide a rough surface for the new paint to grip onto. Once you're done, wash the surface with warm water and a degreasing cleaner and leave it to dry.
If the 80- or 100-grit sandpaper created deep gouges, follow up with 200- and 300-grit sandpaper before moving on to 400-grit. Be sure to wipe the surface clean with a tack cloth afterwards.
After the aluminium is clean and dry, it's time to apply a self-etching primer. Apply 3-4 coats of primer, ensuring you have a solid layer to work with. If spraying the primer, do so in a well-ventilated garage or outdoors.
Drying times between coats will depend on the primer and the air temperature, but in most cases, you can expect to wait around 5 minutes between coats. Once the final coat has dried, proceed to sand again with 400-grit sandpaper and wipe away any residue with a cloth.

You can use a commercial pre-treatment product like "Aluma-Prep" or create your own solution by mixing 18% phosphoric acid (85 wt%), 22% water, 25% isopropyl alcohol, and 35% butyl alcohol. Apply this mixture to the aluminum panels with a cloth or brush, following the manufacturer's instructions, and then rinse it off after a few minutes.
Step 3: Choose the Right Primer
When selecting a primer, opt for an oil-based metal primer or a primer specifically designed for metal surfaces. It is important to avoid primers that contain lead pigments. Aluminum paints designed for metal can also work well as primers. Ensure that the primer is compatible with the type of aluminum roof you have and the paint you plan to use.
Step 4: Apply the Primer
Using a paint roller, brush, or spray equipment, apply a thick, even coat of primer to the entire surface of the roof. Work in sections if needed to ensure complete coverage. Follow the manufacturer's instructions for the best results, including drying times, which can vary from one to three days, depending on the product.
Step 5: Allow the Primer to Dry
After applying the primer, let it dry completely. This step is crucial, as it will ensure that the primer forms a strong bond with the aluminum surface. Follow the manufacturer's guidelines for drying time, which can vary depending on the product and environmental conditions.
By following these steps and allowing adequate drying time, you will create a solid foundation for your paint job, ensuring that it adheres properly and lasts for years to come.
Now that you have a comprehensive understanding of applying primer, you can move on to the next steps of your painting project, including choosing the right paint and applying it effectively.
