Trucks can be prone to rust if you reside in snowy or coastal areas. A little spot of rust can spread and cause severe damage to your truck when ignored. Rust normally appears on trucks due to salt from the road during winter season or the salt content of ocean air, which causes oxidation when these come into contact with a truck’s metal parts.
When rust starts to build up on your truck’s parts, it peels away the paint and weakens metal strength. Your truck’s electronic system can also be affected because it has metallic components that are susceptible to rust.
Restoring a Rusty Truck Frame
Act quickly as soon as you start noticing small patches of rust on your truck. There are three (3) types of rust: surface rust, scale rust, and penetrating rust.
- Surface Rust – Rust that starts from paint scratches or cracks. This type of rust can be easily fixed by using a grinding wheel or sandpaper. Buff out paint and corrosion until the bright metal appears, then apply coat primer, paint, and clear coat respectively. Buff it again to blend.
- Scale Rust – Surface rust can become scale rust when ignored. This type of rust can weaken a truck’s metal strength. Use a wire brush and grinding wheel to get through the rust. Next, use sandpaper to smoothen the surface, then apply coat primer, paint, and lastly, clear coat.
- Penetration Rust – When rust is left exposed for a long time, a truck’s metal sheets will become brittle and start to have holes.
How to Restore a Rusty Truck Frame
