How to check a shop's paint quality and colour matching

Most buyers walk into a panel shop, glance at a test spray on a card, and assume the match is solid. Then they collect the car and notice the colour shifts in sunlight—slightly too blue, a touch too orange, or simply flat compared to the original. By then, the shop claims it looks fine under their booth lights and won't revisit it. The mistake isn't trusting the shop; it's not verifying their process and materials before you hand over the car.

Colour matching is both science and craft. Paint fades from sun and weather, so a 2015 car won't have the same hue as the factory specification from the paint manufacturer's swatch. A credible shop knows this and has systems to account for it. A rushed one doesn't. You can verify a shop's actual capability with a few concrete checks before booking.

Check their equipment and colour-matching method

Start by asking whether they use a spectrophotometer or digital colour-matching tool. This device measures the exact light wavelengths reflected by your car's existing paint and flags the fade factor. Shops that use one are making an objective measurement; shops that eyeball a test card are gambling. Request to see the reading they take from your car—it should be documented and specific, not vague. A good shop will also explain how they account for the paint's age and condition when mixing the new coat.

Ask what paint system they use and whether it's matched to your car's original finish type (acrylic, urethane, metallic, pearl, matte, etc.). Mixing a clear-coat match with a single-stage old paint will look wrong no matter how close the pigment is. Check their records—do they keep a log of colour matches they've done, including make and model? If they do, that's a sign they learn from each job and track patterns.

Visit the shop in person and look at their spray booth. Is it enclosed? Is the lighting consistent and bright? A booth with poor or variable lighting will produce inconsistent results because the spray technician can't see what they're actually spraying. Watch for dust and debris around prep areas—if it's messy, overspray and contaminants are likely to settle on your finish.

Get proof from previous customers

Ask the shop for the names and numbers of three recent customers who had colour-critical resprays—specifically, full-panel or multi-panel jobs where match matters most. Call them directly. Don't ask yes-or-no questions; ask open-ended ones: "How does the colour look in different light? Did you have to take it back? Would you use them again?"

Request to see before-and-after photos from the shop's portfolio, taken outdoors and in consistent daylight. Indoors, most finishes look fine. Outside—where your car lives—is where mismatches show. Ask if you can visit the shop and inspect a recently completed respray on a customer's car (with permission). View it in natural daylight from multiple angles. If the shop refuses or avoids this, move on.

Before committing, ask the shop to spray a test panel—a removable piece like a door card or bumper cover—to your exact specs, using the colour measured from your car. Collect it, take it home, and compare it against your car in different lighting: morning sunlight, afternoon sun, cloudy conditions, and under artificial light. This costs the shop time and materials, but a confident operation will do it. If they resist, they're not confident enough for your job.

Also ask what their warranty covers. Will they revisit the match within the first month if you're not satisfied? Will they charge you, or is it their responsibility if the measurement and spray process was correct? Get this in writing.

Verified spray painters on Strove have customer reviews and can show you ratings for finish quality and colour matching—a shortcut to reputation-checking that saves you the legwork of phone calls. Even so, these direct checks matter, because your car's specific colour, condition, and age is unique. Do them first, and you'll avoid the common trap of a beautiful-looking match indoors that fades into disappointment in daylight.
