How do you fix bubbling paint on a car?

I recently purchased a car from my aunt that runs great but has seen some better days. I want to clean up the vehicle, but how can I fix the bubbling paint?

Congratulations on the new purchase! I’m glad to hear the car runs well, and fixing bubbling car paint isn’t too challenging, but it will require a few supplies and some elbow grease.
To fix bubbling paint on a car, you will need:
  • Putty knife or similar scraping tool
  • Sandpaper
  • Mineral spirits
  • Body filler
  • Primer
  • Paint
Once you have your supplies, you should:
  1. Scrape off the bubbling paint using a putty knife or similar tool.
  2. Remove any rust and smooth the area using medium-grit sandpaper.
  3. Wipe the surface clean, dampen the area with mineral spirits, and let it dry.
  4. Apply one or two coats of primer and let dry.
  5. Apply a body filler to even out the area and let dry until hardened.
  6. Smooth the filler using sandpaper and wipe clean.
  7. Apply touch-up paint until blended with the existing paint.
