How to patch a hole in a fibreglass wall?
1. Tape a sheet of wax paper over the hole using masking tape. The wax paper is going to serve as the start of your fibreglass patch. Place it over the hole so the hole itself is near the centre of the paper. Use one or two pieces of masking tape to secure the wax paper over the hole.

How to restore rust from a car?
Rust restoration involves using abrasives and/or chemical rust removers to get rid of existing rust formation and stop it from spreading. In most cases, you will need to cover the surrounding, undamaged area with tape that won’t damage your vehicle. Once you have used a rust removing product to get rid of the existing rust you will need to paint back over the restored area with primer. To keep rust from returning you should plan on putting on at least a few coats of primer. If the rusted area is too damaged, it may not be worth trying to restore and simply opt for panel replacement.
How to fix rust on metal?
For this you’ll need to use a grinder or drill with a wire wheel, or a chemical compound such as “ metal rescue,” and make sure to wear eye protection and a dust mask. Use the wire wheel carefully to remove the rust that lives in the pits or below the surface area of the metal. Keep in mind that everything needs to be clean! If you use a chemical type rust remover, apply with a paint brush to concentrate your approach. Read the directions on the chemical bottle to determine the amount of time the chemical needs to work before re-cleaning the area. Chemical-based rust remo vers are good for removing rust and any microscopic remains.

How does rust damage a car?
Rust can damage your vehicle in a variety of ways, and the problem will quickly progress if you wait too long to correct it. Over time, minor surface rust can penetrate deeper into the metal. Even worse, what looks to be minor surface rust may just be the tip of the iceberg, as it’s very common for rust to start from the inside of a panel and work its way outward. Ignore rust spots long enough, and you could find yourself with a vehicle filled with flaky rust holes.
How to fix rust spots on truck?
To ensure your truck or car doesn’t deteriorate, it’s important to fix surface rust spots as soon as possible. Start by preparing and cleaning the area. Then, sand rust out with sandpaper or a grinding disk until you see clean metal. After you’ve removed the rust, protect the surface from future corrosion by using Zero Rust paint as a base layer. This product is designed to seal the affected area from oxygen, providing superior rust protection for whatever topcoat paint you apply. Once dried, you can apply an automotive paint to blend the repaired spot into the rest of your paint color.
How to get rid of rust on metal?
Sand Away the Rust: Use sandpaper or a small grinding disc to sand out the rust spot, including the paint directly around the rust area. Keep going until all the rust has been completely sanded out and you see the shiny metal base.

Pro Tip: Fluid Film applied to the undercarriage of your vehicle is an excellent way to protect the chassis and inner body panels from damage caused by road debris and road salts. This protectant is so effective that the marine industry has used it for over 50 years.
What is the most advanced stage of rust?
3. Penetrating Rust. Penetrating rust is, as the name suggests, rust that creates holes in the metal. This type of rust is the most advanced stage. You will need to replace portions of, or entire, body panels of your truck to repair the damage.
What is surface rust?
Surface rust is a straightforward process that is similar to fixing a scratch or paint defect. Scale rust, which goes deeper, requires more effort to get rid of on your vehicle. If you have the right products, though, the process is fairly straightforward.
What causes scale rust?
Scale rust occurs when you leave surface rust to continue the corrosion process until it pits the metal. Chemical reactions cause rust that begins to damage the metal of the body panel itself. Road salts and salt spray are notorious causes of premature rust in cars and trucks, especially in Northern states. These salts create a chemical reaction that speeds up the corrosion process. Eventually, scale rust will work its way through the surface of a body panel and affect the integrity of the metal itself.
How to fix rust on a truck?
The fix is much like general paint repair. Start by using an abrasive wheel or sandpaper (we used 50-grit) to cut through the paint and corrosion until clean, bright metal is visible. Rough up the surrounding areas, too, so that your body treatments can adhere well to the car.
Why does my car rust?
Most surface rust on your car forms when paint breaks down through mechanical or UV damage, which is why even cars in warm, dry climates get it. Structurally, surface rust is not a problem, and depending on the metal's thickness and alloy composition, a level of "passivation" may even be reached where the surface rust actually guards the metal from further oxidation.
Why does salt rust faster?
Then there’s the effect of salt. Road salts and other contaminants dissolved in water act as electrolytes. When electrolytes are introduced to a chemical reaction , they speed up the exchange of molecular components. For drivers, this means that dirty or salty water trapped somewhere in the car's body makes that spot rust faster. It also explains why cars in northern climates where salt is used in winter as well as cars that spend a lot of time near the ocean are prone to rot.
Why are cars sent to early graves?
Otherwise fine cars are routinely sent to early graves because of rust, even though it’s a largely avoidable problem. With iron-based metals, battling oxidation can feel like a Sisyphean task. In spite of the advanced coatings and alloys developed by chemists and engineers, iron’s unstable chemical makeup means it will always succumb to rust in a natural environment. In fact, iron and most steel will completely reduce to iron oxide and other constituent elements over a long enough time.
What is the process of rusting?
Rust forms as a result of the electrochemical breakdown of iron-based metals. This breakdown is the result of oxidation, which is the process where iron surface molecules react with oxygen in the environment and produce a new molecule, Fe2O3, otherwise known as iron oxide. That iron oxide is rust.
How long does steel rust?
Completely untreated raw sheet steel can rust through in as little as a few years.
Why do automakers use aluminum?
Aluminum and magnesium components are becoming popular not only because of their light weight, but also because they corrode at rates that are unnoticeable within a human lifetime. However, those metals are expensive and automakers use them sparingly as a result.
