For best results, please review and follow the full care and application instructions included with your order and available on our FAQ page here.
Sizing
- Rectangular bumper stickers are approximately 8.5” x 2.5”
- Die-cut stickers and magnets are typically 3–4”
- Sizing may vary slightly, especially on hand-cut magnet materials
- Mockup images are not to scale and may appear larger for visibility
Materials
- Made with premium all-weather vinyl
- Waterproof, smudge-proof, fade-resistant, and car wash safe (stickers) when properly applied
- Designed for outdoor use on smooth, clean, glossy surfaces
- Apocalypse-resistant, within reason
Magnets
- Standard magnets are 20 mil thick
- 30 mil extra-thick magnets are available and recommended for colder climates
- Magnets only stick to magnetic metal surfaces. Many modern bumpers are plastic, so please test your vehicle before ordering
- Try your trunk, doors, or side panels if your bumper is not magnetic
Basic Care & Application
- Apply only to a clean, dry, smooth, glossy surface
- Clean the surface thoroughly before applying and dry completely
- Avoid textured, plastic, rubberized, dirty, dusty, waxy, or low surface energy surfaces
- For best results, apply in mild temperatures and press firmly across the full design. Do not apply under 45 degrees F
- Wait 24–48 hours before washing your car after applying a sticker to allow the adhesive to bond
- Remove magnets before car washes or extreme weather (snow/extreme winds)
- Clean under magnets periodically to prevent trapped dirt or debris from affecting your paint
Important Surface Disclaimer
Frog Mustard products work best on glossy, smooth, clean, dry surfaces. Many coolers, kayaks, vehicle cladding, and similar items are made with low surface energy plastics, which can make it difficult for adhesives to bond, even with premium vinyl.
We cannot offer refunds for poor application, failed adhesion on textured/plastic/dirty/incompatible surfaces, or magnet incompatibility with non-magnetic vehicle panels. If you’re unsure about your surface, please message us before applying or purchasing.
