What Blend Time Is
Blend time is the labor required to match paint color on an adjacent panel when you are refinishing a repaired panel next to it. Without blending, the new paint on the repaired panel would not match the surrounding panels due to normal variation in paint color over time, environmental exposure, and the inherent differences between newly sprayed paint and aged paint.
Blending is not optional for a quality repair. It is required by OEM paint application guidelines to achieve an acceptable color match on any vehicle where an adjacent panel is in view of the repaired panel. On a door replacement, blending into the quarter panel or fender is standard procedure.
Why Insurers Deny Blend Time by Default
Insurers deny blend time on a large percentage of estimates because it is one of the most common not-included refinish operations and one of the easiest to deny without explanation. The standard denial language sounds authoritative: "Blend time is included in the adjacent panel refinish allowance" or "Our database does not support a separate blend time charge."
Neither of these statements is accurate. They are form denials issued because many shops accept them without response. The truth, documented in the P-pages of every major estimating platform, is that blend time is explicitly not included in any standard refinish allowance.
The P-Page Documentation for Blend Time
The Mitchell Collision Estimating Guide states that blend time is explicitly listed as a not-included refinish operation and must be negotiated separately for each repair. The guide specifies that areas requiring masking within the perimeter have not been factored into the refinish allowance.
The CCC/MOTOR Guide to Estimating includes the same classification. Blend time on adjacent panels is not accounted for in any refinish labor time and must be estimated and billed as a separate operation. Audatex follows the same convention. These are not shop opinions. They are written definitions from the companies that build the databases adjusters use to write estimates.
The DEG Inquiry That Confirms It
DEG Inquiry #17278, submitted to Mitchell and resolved on record, confirms that blend time is not included in the Mitchell refinish labor allowance. The inquiry asks directly whether masking within the perimeter is factored into the standard refinish time. Mitchell's response is no: that operation requires separate negotiation.
DEG inquiry numbers are not just references. They are published, verified responses from the database provider that any adjuster or appraiser can look up. When you include a DEG inquiry number in your supplement note, you are citing a documented answer from the same company whose database the insurer used to write the denial.
The Supplement Note That Wins Blend Time Back
Use this structure for every blend time denial: "Per Mitchell Collision Estimating Guide (P-pages), blend time is explicitly listed as a not-included refinish operation and must be negotiated separately for each repair. Per DEG Inquiry #17278, Mitchell has confirmed that areas requiring masking within the perimeter have not been factored into the refinish allowance. This operation is required to achieve manufacturer color match on the adjacent panel."
For CCC estimates, replace the Mitchell reference with the MOTOR Guide to Estimating and substitute the appropriate CCC DEG inquiry number. This note gives the adjuster a citation from their own database provider, a verified DEG inquiry, and an operational reason tied to the specific repair.
How Much Blend Time Adds Up to Each Month
A single blend time charge on one adjacent panel typically runs $150 to $300 depending on panel size and labor rate. On a shop processing 30 vehicles per month, blend time denials that go unchallenged can represent $4,500 to $9,000 per month in legitimate revenue that the shop never collects.
Most of those denials are paid when properly cited. The note takes two minutes to write when you have the citation. The math on fighting blend time is straightforward.
