Bondo Car Body: A Comprehensive Guide
What is Bondo?
Bondo is a brand name for a type of automotive body filler, also known as body putty, that is used to repair and fill in dents, scratches, and other imperfections in car bodies. It is a two-part epoxy-based material that consists of a resin and a hardener. When mixed together, the resin and hardener create a thick, putty-like substance that can be applied to the damaged area and allowed to cure. Once cured, bondo becomes hard and can be sanded and painted to match the existing car body.
Types of Bondo
There are two main types of bondo:
* Polyester Bondo: This is the most common type of bondo and is made from a polyester resin. It is strong and durable, but can be difficult to apply and may require sanding and priming before painting.
* Epoxxy Bondo: This type of bondo is made from an epoxy resin. It is stronger than polyester bondo and easier to apply, but more expensive.
How to Use Bondo
To use bondo, follow these steps:
1. Clean the damaged area: Remove any dirt, grease, or rust from the damaged area.
2. Mix the bondo: Mix the resin and hardener according to the manufacturer’s instructions. The ratio of resin to hardener will vary depending on the type of bondo you are using.
3. Apply the bondo: Apply the bondo to the damaged area using a putty knife or spreader. Spread the bondo evenly and make sure to fill in all the gaps and crevices.
4. Allow the bondo to cure: Allow the bondo to cure according to the manufacturer’s instructions. The curing time will vary depending on the type of bondo you are using and the temperature.
5. Sand and paint the bondo: Once the bondo is cured, sand it smooth and then paint it to match the existing car body.
