This Car Runs on Gender Fluid

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.

Sizing

• 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

• Waterproof, smudge-proof, fade-resistant, and car wash safe (stickers) when properly applied

• Apocalypse-resistant, within reason

Magnets

• 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.
