Repair Guide
Repairs span simple maintenance to full engine rebuilds. Master each category to handle any customer who rolls into your garage.
Bodywork & Paint
- Clean dirt and scrape rust before applying filler — adhesion depends on surface prep.
- Fill dents in layers, sanding between coats. Rushing creates visible bulges customers notice.
- Painting requires covering adjacent panels. Move the spray gun steadily; missed spots are a common player complaint.
- Tip: On some jobs, unpainted areas may be hard to spot. Check panels from multiple angles before calling a job done.
Engine & Mechanical
- Disassemble components in order — every bolt matters when reassembling.
- Label or memorize part positions. Swapping similar-looking components causes failures.
- Jack up vehicles securely before removing wheels or suspension parts.
- Test-run engines after major work before the customer arrives.
Fluid Services
- Oil changes: drain fully, replace filter, refill to marked level.
- Coolant and brake fluid have specific fill points — underfilling causes overheating or brake failure.
- Watered-down fuel is a cheap fix with high consequence risk on longer drives.
