Troubleshooting & FAQ

Where is the best place to apply these decals?

For maximum visibility and effectiveness, apply the decal directly on or immediately adjacent to the fuel fill cap. This ensures anyone refueling the equipment sees the "Diesel Only" warning clearly before fueling.

Are these labels resistant to fuel spills and cleaning chemicals?

Yes, these vinyl decals are designed to be durable and resistant to incidental exposure to diesel fuel, oils, and common cleaning agents. However, avoid using abrasive chemicals or high-pressure washers directly on the decal to maximize its lifespan.

How well do these decals hold up in marine (saltwater) environments?

The decals are waterproof and weather-resistant, making them suitable for marine environments. The vinyl material and adhesive are chosen to withstand exposure to sun, water, and salt spray.

Can I reposition the decal after applying it?

The adhesive is designed for a strong, one-time application. Attempting to remove and reposition the decal may damage it or reduce its adhesive strength. Ensure placement is correct before pressing it down firmly.
