How We Research

Every roundup and comparison on this site follows the same six-step method. It's published here so you can check our work, and it's the same method every time — we don't skip steps to make a pick look better.

1. Define the job

Before comparing products, we state the actual paint problem being solved — swirl removal, oxidation, or long-term protection — and the buyer profile it's for: beginner or enthusiast, driveway or garage, occasional use or regular maintenance. A product that's a great answer to one job can be the wrong answer to another.

2. Compile published specs

We pull the manufacturer's own data: pad sizes and orbit/throw for polishers, abrasive grade and cut level for compounds, SiO₂ percentage and stated durability for ceramic coatings, carnauba content and claimed longevity for wax. Every spec we cite links back to its source — a data sheet, a manufacturer page, or a standards reference.

3. Do the math

This is the step most competing sites skip. From the published size and coverage claims, we compute the cost per application, cost per year, and coverage per bottle — a standardized cost-of-ownership figure with the inputs shown, so you can reproduce the arithmetic yourself rather than take our word for it.

4. Cross-reference real-world signal

We aggregate owner feedback and detailer consensus from forums and verified reviews. This is clearly labeled as aggregated signal, gathered and read by us — not a claim that we personally hands-on tested every unit in a lab, because we don't run one.

5. State fit and anti-fit

Every recommendation says who it's for. Just as important, it says who should skip it— a beginner set that's wrong for someone who already owns a rotary, or a coating whose durability claims don't justify its price for occasional drivers. A visible "skip this" call is part of the method, not an afterthought.

6. Disclose what we did and didn't do

If we haven't hands-on tested a specific unit, the page says so, and says what we did instead — compiled specs, computed the cost math, cited the manufacturer, and read the aggregated owner signal. We do not claim owned units, a test lab, or experience we don't have.

What we refuse to claim

We'd rather state plainly what we don't do than borrow the appearance of authority we haven't earned. Here's what that looks like in numbers, and what we do instead of each one:

• Units we claim to have lab-tested: 0. Instead, we compile manufacturer specs and cite the source for every figure.
• Sponsored placements: 0. Instead, rankings come from the method above, applied the same way to every product.
• Free products accepted for review: 0. Instead, every pick is researched from public data, the same information available to any reader.
