We started with a rusty, dented 76 body, bought out of a junkyard with a running motor for two hundred dollars. My plan was to sand the rusty areas with a 3M wheel and then brush apply Rustoleum Metal Primer and then a topcoat. Once rust begins to happen, it cannot be stopped, only repaired. Unpainted galvanized steel panels may need to be painted after being placed in the field. Remove handling marks, debris, or moisture damage by sanding lightly with 220 or 320 grit sandpaper. Treating severe rusting Use an electric drill fitted with a sanding disc or a flap wheel to cut away the surface rust. On areas that you are not going to sand down to bare metal, rough up the surface with the 350 grit paper or coarse steel wool. Step 1, Begin by cleaning the car to remove any dust or potential obstacles for the sander. How To - Picking the Correct Grade Sandpaper for Auto Body Work Automotive I have been working on a car project lately and I had to do a little body work so before I get into the whole project I wanted to give you some help picking the sandpaper you will need for shaping bondo and sanding paint. At this stage, you’re not removing the primer to get to bare metal again. 4 - Sand Down to Bare Metal to Remove Tiny Rust Spots Use a dual action sander, which moves from side to side rather than in circles like an orbital sander, to remove paint over rust that has not penetrated the metal. Then, use pieces of 90-degree angle sheet metal to cover where the cancer was cut out. Stripper compared to sanding: The amount of time involved is a little less with stripper. These colors may be applied to the existing finish, bare steel, aluminum, fiberglass, galvanized surfaces, and various plastics.
