Measure first: which paint gauge reads each panel
Pick a body surface to see which gauge method can read it, what the reading includes and what to check before you measure or polish, from gauge makers' own documentation.
Find your surface
Matches each panel on a car to the gauge method that can read it, so you know before you measure whether a blank or odd reading is expected.

Find your polisher type
Pick a polisher type to see how it moves, which pad sizes and throws it uses, and the jobs it suits or should avoid.

- Multi-mode micro polishers
- Corded polishers
- Cordless polishers
Start with what you need to do
- Cordless polishers and battery platformsExplains how battery platforms work before you buy a cordless polisher, so the tool, batteries and charger you end up with belong together.
- Buying detailing tools safely: sellers, marks and voltageGives the checks that matter before paying for a polisher, gauge or battery online: voltage stated by the maker, verifiable marks and the real seller.
- Polishing pads and backing plates: sizes and fitHelps you match a pad to your polisher's backing plate using the tool maker's own rules, before you order pads.
- Paint thickness gauges: what each type can measureShows which gauge type reads the panels on your car and how to read an accuracy spec, so you buy a gauge that can do the job.
- Used-car paint inspection with a paint thickness gaugeExplains what a paint gauge can and cannot tell you on a used car, so you read panels by comparison instead of trusting one number.
- Car polishers: dual-action, forced-rotation and rotaryExplains polisher motion, throw and pad size in the order you decide them, so you pick a machine that suits the job and your experience.
Tools, shortlists and comparisons
Common buying mistakes
Measuring a plastic bumper with a paint gauge
Magnetic and eddy-current gauges read paint over metal only. On a plastic bumper or fiberglass panel a blank or odd reading is expected; those surfaces need an ultrasonic gauge.
Treating 200 µm as proof of a repaint
Published 'normal' ranges differ by source and market, and factories sometimes repaint. Compare panels and mirrored spots instead: a gauge shows thickness, not the cause.
Assuming any 18 V battery fits
A battery fits a platform, not a voltage number. Even one maker can use different 18 V packs for different tools. Use the tool maker's own packs and charger.
Believing a dual-action polisher cannot burn paint
Maker manuals warn that too much pressure, the wrong angle or improper motion can still cause swirl marks or burning. A dual-action machine is more forgiving, not foolproof.

How we choose
We explain what paint gauges and polishers can do using the makers' own specifications and manuals, certifiers and regulators, and a few named independent sources with their dates. We list only exact models, corded tools only with a maker-stated North American voltage, and we say plainly when we could not tie a seller to the brand. A gauge reading is never presented as proof of a repaint. Nothing here has been tested by us, and we do not cover chemicals or liquids.
