The Best Polisher for Headlight Restoration

A headlight is a 40 square inch curved panel of soft plastic, which is the exact job a 3-inch machine was built for and the exact job a 6-inch one cannot do. Machines, grits and the one thing that decides whether the work lasts.

Top pick

Griot's Garage G8 Mini Random Orbital Polisher

Use a 3-inch machine, not your 6-inch polisher. Griot’s G8 at $144.99 publishes an 8mm throw and takes 2-inch and 3-inch plates, which is the combination that reaches the curve at the edge of a lens where the yellowing is always worst. If you will do this once, skip the machine entirely: a $8.99 Redline 3-inch drill backing plate turns the drill you already own into the right tool, and Redline name headlight polishing on the listing. The grits matter more than the machine — 1000, 2000, 3000, in that order, wet. Live Amazon prices read 7 November 2026.

Griot's Garage G8 Mini Random Orbital Polisher

Why your 6-inch polisher is the wrong tool

A yellowed headlight is not a paint defect. The lens is polycarbonate with a factory UV hardcoat on it, that hardcoat degrades in sunlight, and the yellow haze is the polycarbonate underneath oxidizing. Fixing it means sanding the dead layer off and polishing the plastic back to clarity — which is a different material, a different abrasive sequence and a different machine from anything on the polisher roundup.

The machine problem is geometry. A headlight is roughly 40 square inches of compound curve, with the heaviest oxidation usually at the outer edge where the lens wraps toward the fender. A 6-inch pad rides the high spots and never touches the tight radius. A 3-inch pad follows it. That is the entire argument, and it is why the machines on the mini polisher roundup turn out to be the right tools for a job most people buy a kit for.

The two machines worth owning for this

Griot’s Garage G8 at $144.99 is the pick. Griot’s publish an 8mm orbit throw and a 700 watt motor, and the tool takes both 2-inch and 3-inch backing plates. 8mm on a 3-inch pad is a genuinely useful amount of correction in a small area — enough to level 3000 grit scratches out of polycarbonate without the dwell time a 3mm machine needs. Griot’s publish no speed range, no weight and no warranty term, which is a notable gap at this price. The G8 is also the machine that keeps earning its keep afterwards: pillars, bumpers, mirror caps, badges.

Adam’s SK Pro Micro 2.0 is the cordless alternative, and it publishes three motions on one body — rotary, 3mm and 12mm throw — with a 1.5 inch backing plate, two 12V batteries and up to an hour of runtime at maximum speed, and a published 2,000 to 6,000 per minute speed range. Rotary is the mode that matters on a headlight, because a rotary generates heat and cut in one place rather than spreading it. The 1.5 inch plate limits it to small areas, which on this job is the point. It is sold direct by Adam’s rather than on Amazon.

The cheap route, which is also a legitimate one

Redline’s 3-inch drill backing plate is $8.99 on McKee’s own store and names headlight polishing and scratch removal on the listing. It is hook and loop, it fits any standard drill and it takes 3.75 inch pads. If you are restoring two headlights once and have no intention of becoming a detailer, this is the honest recommendation: a cordless drill has the wrong speed curve and no orbit, and on a 40 square inch plastic lens that matters far less than it would on paint.

Pads are sold separately, which is the catch. The drill attachment roundup covers the cones and balls, and the small pad roundup covers what goes on a 3-inch plate.

The grits are the job; the machine just turns them

Whatever you spin, the abrasive sequence is what decides the result, and this is where most restorations fail — people start too fine, never cut through the dead hardcoat, and get a lens that looks better for a month.

Adam’s sandpaper disc refill packs at $12.99 publish exactly what you need: 1000, 2000 and 3000 grit in 3-inch discs, with orange peel, deep scratches and headlights named as the jobs. Six discs of one grit is $12.99 and eighteen across all three is $32.99 on Adam’s own store, which is the sensible buy — you want all three grits, in that order, wet. Adam’s do not publish whether the discs are rated wet or dry, which is worth knowing before you soak them.

KxK Dynamics P-3000 discs at $10.99 for ten are the finishing grit on a thin foam backing, in 2 inch, which is the size that follows a tight lens radius. One grit only, which is fine as a restock. The wet sanding roundup ranks these against the paint-focused kits.

Chemical Guys’ Easy Grip Hyper Flex block at $22.99 is the hand option, and it is on this page for one reason: Chemical Guys name headlights and paint both, and a flexible block follows a compound curve more faithfully than any backing plate does. No grit, no size and no information about whether paper is included is published, which costs it. Use it for the edges the machine cannot sit flat on.

If the haze is light, do not sand at all

Turtle Wax Renew & Restore wipes at $12.99 are precision abrasives on a wipe, and Turtle Wax name the surfaces explicitly: paint, glass, headlight lenses, chrome, stainless steel and plexiglass, for oxidation, paint transfer, water spots, light scratches and swirl marks. Applied with full hand pressure. For a lens that has gone slightly cloudy rather than properly yellow, this is a ten-minute job with no machine and no masking tape. The wipe count is not published.

Who should buy what

  • You will restore these headlights and then keep detailing: Griot's G8 at $144.99, with 1000/2000/3000 discs and a UV coating.
  • You will do this once: the Redline drill backing plate at $8.99, a set of 3-inch discs, and the drill in your garage.
  • You already own a mini polisher: buy only the grits. The machine on the shelf is the right one.
  • You want cordless and three motions including rotary: Adam's SK Pro Micro 2.0, sold direct.
  • The lens is cloudy rather than yellow: Turtle Wax Renew & Restore wipes at $12.99 and no machine at all.
  • The heaviest oxidation is on the outer curve: the Chemical Guys flexible block at $22.99 for that part by hand.
  • Skip the RUPES iBrid Nano II for this job. It is $515.01 and a headlight does not need it.

Two companion pages are worth reading before you start: how machine correction works for the mechanics of pad, speed and pressure, and what speed to polish at, which applies with one change on plastic: lower, because polycarbonate holds heat.

Each entry lists the specifications the maker publishes, the axis scores those specifications produce, and what you give up.

Questions people actually ask

+Can you restore headlights with a regular polisher?
A 6-inch dual action machine will not follow the curve at the edge of a lens, which is where the oxidation is heaviest, so it leaves a hazy band behind. A 3-inch machine or a 3-inch drill backing plate reaches it. The grit sequence matters more than the machine either way.
+What grit do you use to restore headlights?
1000, then 2000, then 3000, wet, and do not skip a step — each grit removes the scratch pattern the previous one left. Adam’s publish all three sizes in 3-inch discs and name headlights among the jobs. Starting at 3000 on a properly yellowed lens leaves the dead hardcoat in place.
+Why did my headlight restoration turn yellow again?
Because sanding removes the factory UV hardcoat along with the oxidation, and nothing replaced it. The polycarbonate underneath has no UV resistance of its own. A UV coating applied the same day is what makes the difference between a one-year fix and a multi-year one — see the headlight coating page.
+Is a drill good enough for headlight restoration?
