Solution in Metal Dents before the Paint

1. Hazards of rust spots

In particular, paint should not be painted on corroded metal, because in a sealed environment, can further erode the metal, rendering the surface paint ineffective. Repairing rust spot requires some products specifically designed such as sandpaper for metal to work with the metal and inhibit rust. They tend to be chemicals and can be dangerous, so have protective equipment ready when sanding and applying chemicals or paint to metal.

2. How to deal with metal dents?

Usually you need to choose 80 grit sanding discs or sandpapers to start work, carefully sand the surface, remove some metal, of course you can use a sander to improve your work efficiency. Use a wire brush rust removal stains from the metal after picking up the resulting sand and dust with a rag. Then use a putty knife to spread the mixed filler over the recessed metal so that the façade of the pit is level with the rest of the metal. When you can't scrape off the excess filler, you can use medium grit sandpaper or sanding disc pad for sanding, and then choose high grit sandpaper one sanding and polishing, such as P400, P600 to get a smooth surface.
