Foam cannons, or foam guns, have become incredibly popular pressure washer attachments for detailing vehicles. They deliver a thick, luscious foam blanket that makes cleaning cars, trucks, and even RVs much easier and more effective. But these handy tools are often vulnerable to damage without proper storage. This comprehensive guide will walk you through creating a sturdy, protective DIY foam gun case to safeguard your investment. We’ll cover various materials, construction techniques, and customization options.
Why Protect Your Foam Gun?
Protecting your foam gun isn't just about aesthetics; it's about preserving its functionality and longevity. These tools, while durable, are susceptible to damage from:
- Impact: Dropping or bumping the foam gun can easily damage the wand, nozzle, or internal components.
- Weather: Exposure to moisture, extreme temperatures, or sunlight can degrade plastic parts and shorten the lifespan of seals and o-rings.
- Accidental Damage: Storage alongside other tools in a cluttered garage or shed can lead to scratches, dents, and breakage.
A protective case will minimize these risks and ensure your foam gun remains in optimal condition for years to come.
Choosing Your Materials: A DIY Foam Gun Case's Foundation
The success of your DIY foam gun case hinges on selecting appropriate materials. Consider these options:
- Hard Cases: These offer superior protection against impacts but are typically more expensive and heavier. Options include:
- Plastic Storage Cases: Readily available at hardware stores, these are budget-friendly but may not be as durable as more specialized cases.
- Pelican Cases: Known for their extreme durability, these are excellent choices but come with a higher price tag. They're waterproof and crushproof, ideal for transporting your foam gun.
- Soft Cases: These are more lightweight and portable but provide less protection against hard impacts. Options include:
- Tool Bags: A padded tool bag can adequately protect your foam gun from scratches and minor bumps.
- Custom-Sewn Cases: If you have sewing skills, you can create a custom-fitted case using durable fabrics like canvas or nylon.

Design and Construction: Building Your DIY Foam Gun Case
The construction process will vary depending on the chosen materials.
A. Using a Plastic Storage Case:
- Measure Your Foam Gun: Accurately measure the length, width, and height of your foam gun to select an appropriately sized case. Add a little extra space for padding.
- Add Padding: Line the interior of the case with foam padding (available at craft stores) or bubble wrap to cushion the foam gun.
- Secure the Foam Gun: You can use straps, foam inserts, or even Velcro to keep the foam gun securely in place within the case.
B. Utilizing a Padded Tool Bag:
- Select the Right Size: Choose a bag that comfortably fits your foam gun with some extra room.
- Assess Padding: Check the existing padding; if insufficient, add extra foam or bubble wrap.
- Organize Accessories: Use dedicated compartments for storing additional accessories like bottles of soap or extra nozzles.
C. Creating a Custom-Sewn Case (Intermediate Skill Level):
- Draft a Pattern: Create a pattern that accurately reflects the shape and dimensions of your foam gun.
- Choose Fabric: Select a durable, water-resistant fabric.
- Cut and Sew: Cut the fabric pieces according to your pattern and sew them together, adding padding as needed. Include a zipper or other secure closure.
Customizing Your DIY Foam Gun Case: Personal Touches
Once the basic case is complete, consider adding these personal touches:
- Labeling: Clearly label the case with its contents.
- Exterior Pockets: Add pockets for storing small accessories.
- Handles and Straps: Attach handles or straps for easy carrying.
