Overview
This template is a pre-paint refinish checklist for body shop work that needs clean surfaces, properly feathered edges, and accurate masking before primer and basecoat application. It is designed for the prep stage of a repair order, where small misses turn into visible paint defects later. The checklist helps technicians confirm that the panel is cleaned, sanded to the right profile, edges are blended, adjacent areas are protected, and the vehicle is ready for the next step.
Use it when a job is moving from body repair into paint, especially when multiple technicians touch the same vehicle or when the shop wants a consistent handoff standard. It is also useful for mixed-material repairs, blend jobs, and any work where overspray, contamination, or sanding marks would be costly to fix after coating. The checklist is not meant for unrelated maintenance work or for final paint inspection after curing.
Do not use it as a vague “prep complete” status. If a step cannot be verified, it should be marked blocking and resolved before the job advances. That makes the template useful for quality control, technician accountability, and cleaner scheduling in a busy booth queue.
Standards & compliance context
- This template supports OSHA-style shop discipline by making hazardous prep conditions and blocked work visible before the vehicle moves into the next stage.
- If your shop handles regulated coatings or solvents, use the checklist to confirm required prep controls are completed before application.
- For collision repair documentation, the checklist can serve as a quality record showing that surface prep and masking were verified before paint work began.
- If your workflow includes customer, insurer, or OEM requirements, customize the checklist to match those specific prep and verification expectations.
General regulatory context for orientation only — verify current requirements with counsel or the relevant agency before relying on this template for compliance.
How to use this template
- 1. Attach the checklist to the specific repair order or vehicle job so each prep step is tracked against one unit of work.
- 2. Assign the prep technician as the DRI and, if your shop requires it, assign the paint lead to complete the final verification step before the vehicle enters the booth.
- 3. Walk through each checklist item in order, confirming surface cleaning, sanding, feather edging, masking, and contamination control with a yes, no, or N/A result.
- 4. Mark any failed item as blocking, correct the issue immediately, and recheck the affected area before moving the job forward.
- 5. Review the completed checklist at handoff so the next technician knows the vehicle is ready for primer or basecoat and no prep step was skipped.
Best practices
- Keep each checklist item atomic so one line covers one verifiable prep action, not a bundle of unrelated tasks.
- Use N/A only when the vehicle condition truly makes the step irrelevant, such as a masked area that does not exist on that job.
- Treat contamination control as a blocking issue because dust, silicone, and residue are hard to correct after coating.
- Photograph edge feathering problems and masking gaps before the vehicle leaves prep, not after the paint defect appears.
- Set the final verification step with a second set of eyes when the job involves blend panels, jambs, or specialty finishes.
- Match sanding and masking requirements to the coating system being used so the checklist reflects the actual refinish process, not a generic body shop routine.
- Keep the checklist short enough to finish during the prep walk-through, but complete enough to catch the defects that most often reach the spray booth.

Frequently asked questions
What does this checklist template cover?
It covers the prep steps that happen before primer and basecoat application in a body shop refinish workflow. The checklist focuses on surface cleaning, sanding, edge feathering, masking, and a final verification step before paint goes on. It is meant to standardize the handoff from prep to spray so defects are caught early.
Who should run this checklist?
A body shop technician, prep technician, or paint lead should run it, depending on how your shop assigns work. The DRI should be the person responsible for confirming the vehicle is ready for the next stage, not just the person who performed the work. If you use a two-person verification step, the second person should be the paint lead or shift supervisor.
How often should this checklist be used?
Use it every time a vehicle is prepared for primer or basecoat application. It is not a recurring calendar task in the usual sense; it is a workflow checklist that should be attached to each repair order or job ticket. That keeps the inspection tied to the specific vehicle and prevents skipped prep on busy days.
Is this checklist only for collision repair shops?
No, it also fits custom paint shops, fleet body repair, restoration work, and dealership reconditioning. The exact masking points and surface prep steps can be adjusted to match the type of job and the materials being used. Shops that handle mixed substrates or specialty finishes should tailor the checklist to those conditions.
What are the most common mistakes this template helps prevent?
Common misses include incomplete degreasing, sanding scratches left too coarse, poor feather-edge transitions, and masking gaps that allow overspray. It also helps catch contamination from dust, silicone, or residue before coating begins. A final verification step is useful because many defects are easier to prevent than to correct after paint cures.
How does this checklist support quality control?
It creates a clear yes/no record that each prep step was completed and verified before paint application. That makes it easier to spot where a defect was introduced if a finish issue appears later. It also supports consistent handoff between prep and spray, which is important when different technicians handle each stage.
Can I customize the checklist for different vehicles or coatings?
Yes, and you should. Add or remove checklist items for plastic repair, aluminum panels, jamb masking, blend panels, or specialty primers as needed. Keep each checklist item independently verifiable so the technician can answer yes, no, or N/A without ambiguity.
How should this fit into a shop workflow or software system?
Use it as a task type checklist tied to the repair order, with the prep technician assigned as the DRI and the paint lead as the verifier if needed. It works well alongside Kanban-style work queues because it makes blocking issues visible before the job moves to the spray booth. If a step fails, mark it blocking and stop the handoff until it is corrected.
