SUPPLEMENT REQUEST — RO-2026-0471 To: Allstate Material Damage Appraiser From: [Your Shop] Re: 2019 Honda Accord LX · VIN 1HG****621 Date: 2026-04-12 Requesting supplement for the following omitted operations, each supported by OEM repair procedures or I-CAR/SCRS position statements. Labor rate used: $52/hr per original estimate. • Blend LR Door (adjacent panel) 2.5 hr · $130 Authority: Honda Body Repair Manual §4.2.1 Rationale: Adjacent panel refinish requires blending into next undamaged panel to prevent visible color shift. Standard practice when refinishing a single panel bounded by factory finish. • Featheredge, Prime & Block 2 hr · $104 Authority: I-CAR CL17 §2.4 Rationale: Required preparation for any panel receiving repair + refinish. Not included in repair labor. I-CAR position statement explicitly lists as separate line item. • Corrosion Protection — Interior Cavities 0.8 hr · $42 Authority: Honda BRM §2.1.6 Rationale: Rear quarter repair exposes inner panel seams. Manufacturer requires cavity wax application before reassembly to maintain factory corrosion warranty. • Color Match / Let-Down Panel 1 hr · $52 Authority: SCRS Best Practice Guide Rationale: Required on any refinish involving tinted metallic basecoat. Used to verify spray-out matches vehicle under multiple lighting conditions. • Tint Refinement (3-stage adjustment) 1.5 hr · $78 Authority: PPG Refinish Standards §8 Rationale: Honda's metallic Modern Steel (NH797M) requires tint refinement in most cases to achieve invisible repair. Base formula rarely matches factory aged paint. • Pre-Repair Photo Documentation 0.5 hr · $26 Authority: SCRS Administrative Time Guide Rationale: Required documentation for supplement defense. Insurers regularly deny labor without photo evidence of pre-existing vs. collision damage. • Pre- and Post-Repair Diagnostic Scan 1 hr · $52 Authority: Honda Service Bulletin 20-104 Rationale: Honda requires both scans on any collision involving structural components. Blind-spot sensors may need recalibration after LR quarter panel work. ───────────────────────────────────────────────────────── Supplement subtotal: $484 Please review and adjust the approved scope accordingly.
