What is Bondo?Edit
Bondo is a specific brand name of body filler, commonly used in automotive repair. It is usually sold in the form of a gray paste consistency in gallons or quarts. A catalyst hardener is added to initiate curing, which often turns the putty a light pink. When hardened it can easily be sanded to obtain a desired curvature or any other details.
Bondo: How ToEdit
Step 1: MaterialsEdit
- Bondo body filler.
- Additional hardening agent if desired.
- Small mixing container.
- Sturdy mixing stick.
- A spreading utensil such as a plastic knife.
- Sand paper from 80 grit to 300 grit.
- Cheap primer spray paint.
- The piece you'll be detailing.
- A respirator.
- Latex or rubber gloves.
- Safety glasses.
- Long sleeve shirt.
Step 2: WorkspaceEdit
Ensure your work area meets the following.
- Plenty of room.
- Slick surface so messes can easily be chipped away once dry.
- Adequate ventilation.
- Be sure the temperature is high enough to allow proper curing.
- Wear your respirator, gloves, glasses, and long sleeves.
- Make sure the piece to be detailed is heavily sanded. Bondo won't stick to slick surfaces.
Step 3: ApplicationEdit
- Begin by scooping a golf ball sized amount of body filler from the can and into the mixing container.
- Add a strip of hardening agent approximately 1" in length, and begin kneading it into the body filler.
- Once thoroughly mixed, begin spreading the body filler over a small area, making sure there are no empty spaces under the filler.
Step 4: SandingEdit
- Be sure to allow several hours of drying time. Sanding wet filler is difficult as it clumps.
- WEAR A RESPIRATOR - Body filler dust is a very bad thing to have in your lungs.
- Using sand paper as rough as 80 grit, begin roughly shaping the filler.
- Use a sanding block to ensure a smooth surface on flat areas.
- Apply a light coat of primer paint.
- Continue sanding with progressively finer sand paper until all surfaces are visibly smooth, applying additional primer coats to contrast low areas.
Spot Putty TutorialEdit
Step 1: MaterialsEdit
- Latex Gloves
- Bondo Spot Putty
- Armor Piece Etc.
- 220-360 grit sandpaper
You probably have Bondo on your piece already, the spot putty is to smooth the areas where Bondo may have gotten chipped or is uneven.
Step 2: ApplicationEdit
- To properly open the tube of glazing putty, take the cap off, turn it upside down and push it onto the tube.
- Squeeze from the back of the tube such as anything else, you want to get out as much as possible.
- Sand down rougher areas.
- If you have your spot putty with you and your rubber/latex gloves on, dab some on your finger.
- Apply to areas that need it most, it runs out fast.
- You will need to sand the spot putty later, so don’t bother getting it super smooth.
- Once you have your spot putty applied to your piece, take your sandpaper and sand it to make a smoother.
- If some areas where the bondo is is a lump or blob, sand it down before applying spot putty, it will make your life a lot easier.
- Once done, let harden for 25 minutes or more and then paint over it.
