One of the most dreadful things to every car owner is to find your truck frame covered with rust. It might start with a scratch or a dent. If you ignore, with time the rust will spread like a rash. It will peel off the paint, weaken the metal strength and eventually get rust holes. So, what causes the metal of your car to rust? When the metal gets exposed to a mixture of water and oxygen, oxidation occurs, causing it to rust. Salt accelerates oxidation. That’s why during winter many vehicles get rust. Even if the rusty spot seems small on the outside, inside the panel, it might be more. So don’t ignore it. Here are three main types of rust.
Types of Rusts
Do you know how to restore a rusty truck frame? If you don’t, relax. It’s essential to know the type of rust that is on the frame of your trunk. It could be surface rust, scale, or even penetrating rust. Knowing their difference will help you understand the right approach. Here are the differences.
Have you ever inspected the body panel of your vehicle and noted that the top layer is rusty? That is the surface rust. If you have, you should take action immediately to stop it from spreading further. Luckily, you only require a little effort to treat it. Buy some automotive paints that match the color of your vehicle to avoid that problem. Whenever your car gets minor nicks or even scratches do some touch-ups. Below are quick steps of fixing surface rust.
- Start by gathering all the materials that you require. They include; a plastic sheeting and painter’s tape. Also get sandpaper, wire brush and wax as well as a grease remover. A microfiber cloth, Body filler and applicator are also vital. Finally, you also need an automotive paint( it should match your car)
- Prepare your working space- Since you only want to deal with the affected part, taping plastic sheeting will help you to cover the other part enclosing the surface that you want to treat. Leave a margin around the affected surface.
- Put on your safety gears which include gloves and dust masks. You should also protect your eyes using the protective eyewear.
- You need to clean the area first using a wax and grease remover.
- Use sandpaper, to sand off the rusty place thoroughly. Don’t stop until the metal base becomes shiny.
- Using the wax and grease removal, clean the surface again.
- Using a lint-free cloth, wipe off any dust that might have accumulated.
- Apply rust-prevention paint such as zero rust. If you don’t have zero rust, use any other automotive primer or even paint.
- Using a microfiber cloth, buff the treated area.
- Wait for at least 30 days before waxing your car.
Note that, washing the surface before sanding off the area protects the surface from getting contaminated.
If you neglect the surface rust, it will accelerate and damage the metal panel. That stage is called scale rust. It occurs mostly in northern states where they use salt spray or even pour salt on the road. Salt accelerates corrosion process causing the metal to get weaker. So, what’s the best way to remove rust from the truck frame? Check below.
- Start by getting the right materials.
- Prepare the area- using plastic sheeting and a tape; cover the area that surrounds the rusty area. Leave a space of 6 inches in all sides.
- Wear protective gears.
- Using wax and grease removal clean the surface.
- Using an aggressive grinding tool, remove the heavy scale rust. Use a less aggressive grit to remove any left rust that surrounds the paint.
- Mix hot water with zero rust and put the mixture in the spray bottle. Spray the affected area.
- Use a body filler to fill in depression in your pitted metal.
- Use sandpaper for sanding the area smooth.
- Clean the surface again using the wax and grease removal.
- Use a lint-free cloth to wipe off the dust.
- Apply primer and paint two coats each. Wait for each to dry first before applying the other one.
- Use a lint-free cloth to buff the dried coating.
- Wait for 30 days before waxing.
It is the most advanced stage. Just like the name suggests, rust penetrates creating holes in the metal. Unfortunately, dealing with this type is expensive. If a small portion is affected, you might have to replace that portion. In the worst-case scenario, you might have to replace your trucks body panel. The best way to avoid this type of rust is to treat surface rust whenever you see it immediately.
