All bare metal is susceptible to rust, including the metal in your car. To safeguard your vehicle, promptly address any spots as they appear since they can spread quickly. Failure to act on small spots can lead to significant issues over time. This guide provides essential tips on removing it from your car to help maintain its condition and prevent buildup.
Firstly, clean the affected area thoroughly to eliminate oils, dirt, or any impurities. Ensure the area is completely dry before proceeding further.
If it’s present on specific parts like body panels, chassis, or frame, isolate it by masking off other metal areas. This containment strategy helps concentrate its removal efforts on that specific section.
There are a lot of good sprays in the market, and truthfully, they share similar properties. The brand choice isn’t critical; rather, focus on following the specific instructions provided for proper removal and product usage.
If the problem persists after using the spray, manual effort with sandpaper is required. As you progress through the sanding, pause occasionally to clean and examine the surface. Isopropyl alcohol is effective for cleaning as it dries quickly without causing rust.
After eliminating rust, ensure thorough cleaning of the area by using degreasing or automotive soap to remove its remaining particles, grease, or other impurities. Finally, rinse and dry the surface.
A tack rag, commonly utilized for dust or surface impurity removal before painting, is occasionally used by individuals. For surface rust elimination, it is suggested to use a blend of Isopropyl Alcohol and distilled water in a 30/70 ratio. This solution should be sprayed onto the area and then wiped clean using a new microfiber towel.
If you’ve used sandpaper on a painted area affected by rust, sand off the color layer entirely and apply a primer to the entire section. This ensures an even primer coating for proper painting. If it is on bare metal, apply a metal clear coat to that area.
Wash and dry the area and mask off the area as we explained above.
Before operating the grinder on metal, make sure to wear gloves and eye protection. Start grinding the rust slowly, moving from left to right. Avoid attempting to remove all of it in one go; instead, focus on gradually eliminating it by moving back and forth. This approach helps maintain a more level surface. Seeking assistance from a professional or attempting this task only with prior experience is highly recommended for optimal results. For this, it’s always better to get help from a professional or do it only if you have experience.
Follow this step once all rust has been removed.
For skilled experts familiar with car care procedures, in the past, a product called Bondo, which is a putty made of a special kind of plastic, was used to fill rust holes. Nowadays, there are newer and improved options available that follow the same basic idea. To use this putty, prepare it properly and spread it evenly over the affected area using a putty knife. Follow the instructions from the manufacturer to let it harden properly for the best outcome. Make sure it dries completely, which might take about a day depending on the specific product chosen.
In this stage begin sanding with fine grit sandpaper, typically above 500, gradually progressing to even finer grit, reaching around 1,500. Some body-filler products offer a scratch sealer that can be applied after this step, followed by wet sanding for a smooth, scratch-free surface.
You get to decide this step because different surfaces need different paints or primers.
While the WD-40 Multi-Use Product is commonly known as a lubricant, its innovative formula works effectively for cars. Its unique properties work by breaking the bonds between rust and metal, penetrating the porous layer, and lubricating the surface for removal.
Eliminating rust from metal on any vehicle isn’t a straightforward process. It varies based on its severity, metal condition, and the likelihood of future rust. You’ll have several options to consider for the task. And sometimes, it’s better to replace crucial safety components like frames and chassis instead of repairing them.
