What Is Bondo And Primer?
Bondo is a body filler that seals dents, cracks, and holes in a car’s bodywork. It’s made up of polyester resin and hardener. On the other hand, primer is a preparatory coating that is applied to the surface before painting.
It adheres well to the surface and improves paint’s adhesion and durability. When it comes to sticking to primer, bondo can stick to it, but only if the surface is properly prepared. This involves sanding, cleaning, and priming with the right primer.
Using the wrong primer or not preparing the surface correctly can result in the bondo not sticking to the primer. It’s essential to understand bondo and primer and their properties before using them to ensure a durable and flawless finish.
