The Hidden Labor Gap: What Refinish Times Leave Out of Your Estimates

Ask most estimators what's included in a panel refinish time and they'll tell you something like: wash, scuff, prime, seal, basecoat, clearcoat. They'd be right — and that short list is precisely the problem. According to collision repair experts, the gap between what an estimating system calculates and what a technician must actually perform is enormous, and shops that don't manually add the missing operations are doing a significant amount of work without compensation.

Collision Hub CEO Kristen Felder and co-hosts Larry Montanez of P&L Consultants and Mark Olsen of Vehicle Collision Experts have dedicated significant time to documenting what isn't covered in standard refinish times across every major estimating platform. Their conclusion: all four major panel categories — new OEM metal, new OEM plastic, aftermarket, and recycled — share the same abbreviated base times, with a long list of additional operations left for the estimator to discover and manually add.

New OEM Metal Parts

On the surface, a brand-new OEM metal panel sounds like the ideal candidate for a clean, simple refinish job. In reality, removing that panel from the box and preparing it for painting could involve at least fourteen distinct operations not captured in any estimating system's base time.

Sticker removal alone can consume meaningful time. Felder has observed panels arriving with multiple labels affixed by the supplier. Shops tempted to use heat should check the panel substrate first — higher-strength steels and aluminum are heat-sensitive, and what works on mild steel can cause significant damage on more advanced materials.

Solvent testing is required because parts arrive in shipping primer or e-coat, and the fact that paint may adhere to a surface doesn't guarantee that surface will hold to the underlying substrate. Montanez has emphasized that skipping this step is where paint failures originate — and why a paint manufacturer won't warranty work done without it.

Color lookup, mix and match sprayout, and tinting to achieve a match are all additional time expenditures not built into any system's base time. Montanez noted that Mitchell, CCC, and Audatex each handle sprayout differently — Audatex includes one mix-and-match in its time, while Mitchell and CCC do not — but all three acknowledge a range of 0.1 to 1.0 hours in variance, averaging 0.5 hours. Three rounds of color matching could easily represent 1.5 hours of uncompensated painter time.

Other commonly missed items include matte application (basecoat alone won't produce the correct finish), back-of-panel corrosion protection (new fenders, for example, still require epoxy on interior surfaces), etch or wash primer when a technician inadvertently cuts through a surface, anti-chip primer on hoods and other commonly specified areas, blow-off and tack, and masking beyond 36 inches (anything more extensive than the basic car cover configuration adds time not included in base figures).

Felder offered a vivid description of what a proper estimate looks like: take a new OEM hood out of the box, calculate a refinish time for the R&R operation, and then expect "another good 12 lines" beneath it capturing all of the not-included operations. Simply clicking "replace part" and accepting the system-generated time is what many shops do — and it's leaving money on the table every single time.

New OEM Plastic Parts

Plastic panels present most of the same not-included steps as metal panels, plus several unique ones.

Mold release cleanup — removing residual material from the forming process — must happen before painting, not after. Montanez pointed out that fresh paint can take two days or more to fully cure, so attempting to clean mold residue from a newly painted panel risks pulling the paint off with it. The right time to address it is during a technician's trial fit, when the residue becomes visible.

Adhesion promoter represents both a labor and material cost that standard material calculators will miss entirely. Raw bumper prep, flex additive, and masking of blackout areas on bumper covers are all additional operations that Felder noted are frequently found on plastic components and almost universally missed during estimating.

Welded OEM Panels

When a repair involves a welded structural component — a quarter panel, for instance — the not-included operations multiply significantly. Felder has stated this is where she believes shops lose the most money and time.

Any panel touched during the welding process transitions from a blend candidate to a full refinish panel. That distinction matters: it's no longer a blend operation, it's the complete refinish time applied to every affected panel.

Adjacent panels also require prep work before refinishing. Replacing a quarter panel can potentially require preparation of 22 additional panels. At even 0.1 hours each, that's substantial unrecorded time.

Olsen was direct about the operational reality: the work is being done. Technicians are performing every one of these steps. The problem isn't incomplete repairs — it's incomplete documentation, and the financial consequence falls on the shop and its technicians.

What the P-Pages Actually Say

All three major estimating services are reasonably transparent about their limitations in their procedure pages (P-pages). Mitchell's language is unambiguous: "Refinish times in this Guide pertain to NEW, UNDAMAGED PARTS." CCC states that "Published refinish times are for one color applied to new undamaged OEM replacement components." Audatex describes a setup formula that covers five items: covering the car, tack wipe, gathering materials, mixing and applying clearcoat, and cleanup.

Everything else is manual entry. Shops that understand their P-pages understand the scope of what they're leaving unclaimed. Those who rely solely on system-generated calculations are consistently under-documenting their actual repair costs — and running a business that can't sustain itself over time.
