Gender Fluid Bumper Sticker – "This Car Runs on Gender Fluid" Vinyl Decal
Fuel Up. It's Not Just the Gas That's Unleaded.
Introducing the bumper sticker that makes cis drivers nervous and queers honk in solidarity: "This Car Runs on Gender Fluid." Printed on 8.5" x 2.5" weatherproof vinyl or a thick 20mm or 30mm magnet, this bumper sticker is built to survive the road, the rain, and your third identity crisis this week.
Designed by Frog Mustard—America’s most unhinged sticker dealer—this one isn’t subtle. It’s built for boldness, back windows, and people who know the difference between a tank top and top surgery. It’s part protest sign, part punchline, and part personal mission statement.
No boring corporate rainbows here. No clean lines. Just raw, road-safe queerness slapped across your tailgate with pride.

- Die-cut stickers and magnets are typically 3–4 inches.
- Sizing may vary slightly, especially on hand-cut magnet materials.

Materials
- Made with premium all-weather vinyl.
- Stickers are waterproof, smudge-proof, fade-resistant and car-wash safe when properly applied.

Magnets
- Standard magnets are 20 mil thick.

- 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 allow it to 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 below 45°F.
- Wait 24–48 hours before washing your car after applying a sticker so the adhesive can bond.
- Remove magnets before car washes or extreme weather, including snow and high winds.
- Clean beneath magnets periodically to prevent trapped dirt or debris from affecting your paint.
Important Surface Disclaimer
Frog Mustard products work best on glossy, smooth, clean and 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 when using premium vinyl.
We cannot offer refunds for poor application, failed adhesion on textured, plastic, dirty or otherwise incompatible surfaces, or magnet incompatibility with non-magnetic vehicle panels. Please message us before applying or purchasing if you are unsure whether your surface is compatible.
