Bondo resin can fill in smaller dents in a automobile's side.
Operate the spatula to manipulate them together quickly. Start with only a small batch because the resin hardens very quickly. You want to be able to cover the dent before the resin gets too hard to use.4. Eliminating fiberglass allows you to applicability the resin on smaller areas and avoid getting fiberglass particles In all places.
Instructions
1. Disinfected the surface of the motorcar that needs repair using soap and drench. Remove any develop and grease with a increase remover. Cause not advantage as well still widen remover. Honorable a swipe or two is Sufficiently.
2. Sand the surface of the dent to approximately two inches away it, baring the metal. Bondo resin should be used directly on metal, or your repair Testament one be as bulk as the dye underneath. Scratch the metal with 80-grit sandpaper to cede the metal a rougher surface. This gives the resin and hire and a stronger clasp on the metal. One sand two or three times --- the intention is a roughened surface for the resin, not to expose the grain of the metal.
3. Situate on your protective gloves and respirator mask, then blend a mini batch of resin. Pour away a petty bigness of resin into your bowl or palette, or scoop absent whether it a thicker object filler. Add hardener according to the directions. With Bondo object filler, you committal solitary a tiny ribbon of cream hardener for a golf-ball-sized scoop of resin.Bondo is a Trade-mark cognomen for resin used to set cars. The resin is mixed with another chemical called a hardener, and the homogenize is applied to fiberglass over problems in the away target of the machine, such as dents and gouges. Bondo can be used without fiberglass, remarkably in the body filler formulation, which is thicker than the typical liquid resin and easier to spread down the sides of the machine.
Spread the mixed resin onto the dent with the spatula. Smooth it down quickly into the area you sanded. Allow it to cure, which take roughly three to ten minutes. After the resin cures, it is safe to touch. When testing the dryness, use the back of your finger; the oils in your fingertips will cause uncured Bondo to buckle up when you lift your finger.
5. Sand the area once it is dry and add the second coat of Bondo. This sanding does not have to be perfect. Mix a new batch of resin and hardener, since anything left of the old batch is useless. This second layer of resin is called the skimcoat and should extend past the filled dent to smooth onto remainder of the car's body.
6. Allow the skimcoat to cure, then sand it. The dent should be filled by these two layers, but you can add another layer of resin if necessary. Sand with the 80-grit sandpaper, then switch to finer papers and prepare to repaint the surface once it is smooth. Fine-grit sandpapers are smoother and are indicated by higher numbers. Use a 200-grit sandpaper after the 80-grit paper, and finish with 400-grit paper. These will give the area a smoother finish, without scratches from the sand in the paper.
