One-step vs. multi-step correction: Selecting the right process

Choosing the correct paint correction workflow is the most critical decision for a high-volume Detail Shop. It is a balancing act between the "Pursuit of Perfection" and the "Reality of Profit." In this technical guide, we break down the SOPs for selecting the most efficient method for every vehicle that enters your bay, ensuring you meet customer expectations without "over-working" a job and losing your hourly margin.

1. The One-Step Correction (The "Enhancement")

The one-step is the "bread and butter" of a professional B2B operation. It is designed to remove light swirling and oxidation while leaving behind a high-gloss finish.

• Goals: 50-70% defect removal.
• The Setup: Use a "Medium-Fine" foam pad and a "Hybrid" polish that contains both diminishing abrasives and finishing agents.
• Best For: Newer vehicles, Fleet Accounts, or as a prep-step for an entry-level sealant.
• Shop ROI: High. A one-step can often be completed in 3-5 hours, allowing for a higher Job Density.

2. The Multi-Step Correction (The "Restoration")

This is a dedicated restoration process intended for neglected paint, deep "RIDS" (Random Isolated Deeper Scratches), or preparing a high-value collector car for a Ceramic Coating.

• Goals: 85-95% defect removal.
• Stage 1 (Compounding): Use an aggressive wool or microfiber pad with a heavy compound to "level" the clear coat. This will leave behind "haze" or "tick marks."
• Stage 2 (Polishing): Follow up with a fine foam pad and a finishing polish to remove the haze and restore mirror-like clarity.
• Shop ROI: High Ticket, but lower hourly rate. A multi-step can take 10-20+ hours. It should only be sold to customers who are willing to pay for "Showroom Quality" results.

3. The Technical Decision Tree

How do you decide which one to use? Never guess; always test.

• The "Test Spot": Perform a 1x1 foot section on the hood or trunk. Start with the least aggressive method (One-Step). If it meets the customer's agreed-upon goal (e.g., "remove the dullness"), stop there.
• Paint Depth Analysis: Use a Paint Depth Gauge to ensure there is enough clear coat remaining to support a multi-step correction. If the paint is "thin," you must stick to a one-step to avoid "burn-through" liability.
• Lighting is Critical: You cannot correct what you cannot see. Use specialized Inspection Lighting to reveal the true state of the defects before making your recommendation.

4. Selling the Result, Not the Process

Customers don't care how many "steps" you do; they care how the car looks.

• The "Gloss Enhancement" vs. "Defect Removal": Most retail customers want "shiny." Most B2B collectors want "perfect." Use your Price Framework to align your labor with their specific desires.

How DetailerBase Supports Your Correction Workflow

• Before & After Gallery: Store high-resolution photos in the Booking Profile to prove the results of your multi-step labor.
• Internal Tech Notes: Record the pad/polish combination used on a specific vehicle so your Staff can replicate the results if the customer returns for a partial repair in the future.
• Transparent Invoicing: Use our Invoicing System to clearly list "Stage 1 Compounding" and "Stage 2 Polishing" as separate value-adds, rather than just a generic "Buffing" fee.
