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.

Vinyl vs. Magnet – Choose Your Fluid State

Vinyl:

• Weatherproof and semi-permanent

• Great for cars, coolers, laptops

• Stick it and own it

Magnet:

• Available in 20mm or cold-resistant 30mm

• Swappable, durable, chaos-ready

• Great for metal bumpers, lockers, or your ex’s fridge

❗ DISCLAIMERS:

Mockups:
Mockup images are not to scale. May be larger in images for viewability. Colors may vary slightly.

Application Disclaimer:
– We can’t offer refunds for application to textured, plastic, or dirty surfaces, or for poor application practices.
– 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 (LSE) plastics, which make it hard for adhesives (even premium vinyl) to bond.
– You assume the risk if you apply to a weird or incompatible surface.

👉 If you're applying to an LSE plastic and love our designs, message us — we’re happy to chat about higher-tack vinyl options for tough surfaces.

💡 For DIY adhesion help, many folks use Mod Podge, 3M Super 77 spray adhesive, or apply a little heat and pressure during application.

Air Bubbles (Magnets):
Small air bubbles under magnets are normal and usually disappear with time/heat.

Magnet Compatibility:
Many modern car bumpers are plastic and won’t hold magnets — try your trunk, doors, or side panels instead. Test a magnet on your car before purchasing. We cannot refund for those that do not check.

Longevity:
While our materials are built to last, extreme weather or improper surface prep can shorten product life.

Duplicates (Mystery/Misprints): Mystery and misprint packs may include duplicates. That’s part of the gamble. Misprints are subject to what is on hand that has been misprinted. If you do not want duplicates, buy a non-misprinted bundle.

Design Ownership:
All designs are original and created for humor/novelty. Parody and satire are protected speech.

No Custom Orders via Notes:
We can’t honor custom requests left in order notes for non-custom products. Please contact us before purchasing.

Stolen or Lost Mail:
Once your package is marked delivered, we unfortunately can’t replace lost or stolen mail. Please ensure your shipping address is correct and secure.
