How many stickers fit on a car — and how does earning work?

Four spots per car — one circle sticker per door, no hood. A full four-door set can earn up to $500 a month.

Four. A car on Lunar (lunarcar.me) carries up to four circle stickers — one per door, front and rear on both sides, and nothing on the hood, glass, or bumpers. Each filled spot earns on its own monthly payout cycle. Fill all four on a typical four-door car and you can earn up to $500 a month. Here's how the spots work, how earning works, and the choices you control.

The four spots, and why doors only

The door panels are the flattest, most visible, least risky real estate on a car — big enough for a readable circle, flexed less than bumpers, and clear of anything a vehicle-equipment rule cares about (windshield, lights, plates). No hood sticker, ever: hoods curve, bake in engine heat, and sit in the driver's own eyeline. Two spots face each sidewalk, which is the point — a parked car advertises to both sides of the street, and a parked car keeps earning.

How a sticker earns

• Pay: each filled sticker earns on its own monthly cycle — flat, for carrying the sticker and keeping verification current.
• Ceiling: a full four-door car can earn up to $500 a month.

You choose how many spots to fill

One to four, no minimum. Some drivers start with a single door to see how it feels; most add spots once the first payout lands. Each spot is matched independently — different local businesses, never the same brand twice on one car — and each runs its own monthly pay cycle from its own start date. You can name businesses you would like to carry and Lunar looks at those first, though a match is never guaranteed; Lunar's team matches the rest from paying businesses in your zone, and you can decline any match you are offered. The full pairing logic is in how Lunar matches drivers with local businesses.

How the spots add up

Two-door cars and coupes carry two spots — half the inventory, same per-sticker pay. SUVs and trucks with four doors carry the full set (the panels are bigger, but pay is per sticker, not per square inch). See the earnings page for what your car can earn.

Why not more spots?

Because saturation kills the medium. A car shingled in ads reads as a billboard on wheels — exactly the corporate look Lunar's neighbour-to-neighbour model avoids, and the reason wrap networks and Lunar are different products. Four clean circles on four doors reads as a person backing some local businesses, which is what makes the impression land. It also keeps each advertiser's sticker legible: four brands per car is inventory discipline, not a technical limit.

Filling all four, practically

Stickers arrive by mail as spots match — install on the assigned door, photo to verify, done in minutes. Cycles stagger as spots fill at different times, so a full car sees deposits spread across the month rather than one lump. If a campaign ends, the spot refills from the pool and its clock restarts. Keep up the weekly check and the car reasonably clean, and four doors quietly become a monthly line item of up to $500 for driving you were already doing — no deposit, no fees, and never a reason anyone should ask you for money to participate.
