Buying Guide: Key Purchase Considerations
- Surface compatibility: Most magnetic signs work on ferrous steel panels. They won’t stick to aluminum or fiberglass. Verify your vehicle material before purchase.
- Size and visibility: Larger signs increase legibility from a distance. Match sign size to your door surface and target viewing distance.
- Durability: Look for weatherproof, UV-resistant vinyl or magnetic vinyl with rounded corners for long-lasting use in sun, rain, and wind.
- Customization options: If you want logos, text, or photos, consider signs that support full-color digital printing or easy DIY customization with vinyl sheets or dry-erase surfaces.
- Installation and removal: Ensure signs lay flat and have strong magnetic holds that resist wind at highway speeds. Avoid signs with weak backing that can peel or curl.
- Compliance and safety: For fleet signage, confirm DOT/MC labeling requirements and any state visibility standards for lettering size and color contrast.
