Car welding: when rust starts eating your car, and how to stop it

Rust is like a silent killer. It starts as a small, innocent bubble in the paint and ends as a hole in the floor through which you can see the tarmac. Latvia’s changeable weather and the generous amounts of salt spread on the roads create an “ideal” environment for corrosion. In this article we look at why car welding is a service you are better off not leaving too late.

Which parts rust most often?

It’s no secret that corrosion doesn’t treat every part of a car equally. It has its “favourite” spots:

1. Sills: They take the biggest hit from stones, salt and water.
2. Wheel arches: The place where moisture and mud linger longest.
3. Floor pan and chassis: Often the owner has no idea there’s a problem until the car goes up on the lift.
4. Fuel tank mounts and brake lines: Critical areas for safety.

The “kings of rust” and the role of the environment

Although modern cars are galvanised, some models have historically rusted “faster”. These are often older generation Mazda (especially the Mazda 6), Mercedes-Benz (E and S Class up to the mid-2000s) and certain Nissan or Opel models.

Important note

Rust isn’t just the manufacturer’s fault. It depends directly on the environment. A car that spends its winters in salty puddles on the streets of Riga and isn’t washed regularly will rust 5 times faster than an identical car driven in drier regions or kept well maintained.

How can you make your car rust less?

You can’t stop nature completely, but you can slow it down:

• Anti-corrosion treatment: An investment that pays for itself twice over.
• Regular washing in winter: Wash the salt off before it starts reacting with the metal.
• Fixing damage promptly: Even a small scratch through the paint is an open door for rust.

A real story: a small bubble versus an empty wallet

Recently two customers came to us at GT Garage with exactly the same problem: a rust patch on the sill.

• The first case: The customer acted straight away. The welding work was minimal, and the affected area was cleaned, treated and finished. The cost was relatively low and the car looked as good as new again.
• The second case: The owner decided to wait a year. When the plastic trim was removed, it turned out the sill had completely rotted through on the inside and the rust had also reached the load-bearing elements of the floor. What would initially have taken a couple of hours turned into a complex, multi-day job with a full sill rebuild.

The conclusion is harsh: When it comes to rust, time is money. Real money, straight out of your pocket.

GT Garage: we don’t patch, we restore

At our workshop, car welding isn’t just “patching a hole”. We take a thorough approach:

1. Inspection: We find every corrosion spot, not just the ones visible on the surface.
2. Quality welding: We use the right materials and techniques so the welds are durable.
3. Protection: After welding, the parts are primed, painted and treated with anti-corrosion products so the problem doesn’t come back after the first rain.

Is your car safe? Don’t wait until rust wins. Bring it to GT Garage and we’ll make sure your car keeps serving you for years to come!
