Protect Your Mazda 3 from Rust: Comprehensive Guide

Understanding Rust Problems on the Mazda 3

The Mazda 3, beloved for its sleek design and reliable performance, is not immune to rust issues, especially as it ages. Identifying and addressing rust problems early can save you from costly repairs and maintain your vehicle’s appearance and value.

Common Rust Areas on the Mazda 3

Mazda 3 models, particularly the Mk3, are prone to rust in specific areas. Here’s where you should be vigilant:

  • Wheel Arches: One of the most frequent complaints among Mazda 3 owners is rust around the wheel arches. The exposure to road salt, debris, and moisture makes this area highly susceptible to corrosion.
  • Sills and Undercarriage: The underside of the car, including the sills, is another area where rust can develop. Dirt and water can accumulate here, leading to gradual but significant rust damage.
  • Door Edges and Boot: Rust can also appear along the edges of the doors and boot due to trapped moisture, especially if the sills are worn out or damaged.

Visual Guide: Rust on the Mazda 3

To help you spot rust on your Mazda 3:

  • Wheel Arch Rust: Noticeable rust forming around the edges of the wheel arches, often where the metal meets the plastic trim.
  • Undercarriage Rust: Rust patches on the sills and undercarriage, visible upon close inspection, especially in untreated areas.
  • Door and Boot Rust: Small rust spots along the seams and edges of the doors and boot, often starting as bubbles under the paint.

How to Prevent Rust on Your Mazda 3

Preventing rust is crucial to keeping your Mazda 3 in top condition. Here’s how you can protect your vehicle:

  1. Regular Cleaning: Wash your Mazda 3 regularly, especially during winter when road salt is prevalent. Focus on the wheel arches, undercarriage, and door edges.
  2. Apply Rust Protection: Use Lanoguard’s rust protection spray to safeguard your vehicle. It’s easy to apply and provides long-lasting protection against rust.
  3. Check and Repair Sills: Inspect door and boot sills regularly. Replace any worn or damaged sills to prevent moisture from entering and causing rust.

2015 Mazda 3

The 2015 Mazda 3, part of the third-generation (Mk3) lineup, has some specific rust issues that are more prominent than in other model years. These issues are largely due to the materials used and certain design aspects of this model. Here are the key rust issues specific to the 2015 Mazda 3:

  1. Wheel Arch Rust
  • Prominence: The 2015 Mazda 3 is particularly prone to rust around the wheel arches. This area tends to trap moisture, dirt, and road salt, especially in regions with harsh winters. The metal edge where the wheel arch meets the plastic trim can corrode more quickly, leading to visible rust.
  • Why It's Worse: Compared to earlier models, the 2015 version's design may allow for more accumulation of debris in this area, exacerbating the rust issue.
  1. Undercarriage and Sills
  • Prominence: The undercarriage, particularly the sills, is another area where rust is more prominent in the 2015 Mazda 3. This is due to the vehicle's low profile, which causes it to pick up more road grime and salt than some other models.
  • Why It's Worse: The 2015 model may have less protective coating compared to some newer iterations, leading to increased vulnerability to rust in these areas.
  1. Boot and Door Edges
  • Prominence: Rust around the edges of the boot and doors is common in the 2015 Mazda 3. This typically starts as small bubbles under the paint, often due to moisture getting trapped in the seams.
  • Why It's Worse: The sills around the boot and doors in the 2015 model may not be as robust as in later years, leading to more frequent rust issues here.
  1. Roof Rust Near Windshield
  • Prominence: Some owners of the 2015 Mazda 3 have reported rust developing on the roof near the windshield, a problem less commonly noted in earlier or later models.
  • Why It's Worse: This could be due to a combination of the roof design and the materials used, which may be more susceptible to corrosion from environmental factors like rainwater pooling in certain areas.
  1. Front Subframe Corrosion
  • Prominence: The front subframe of the 2015 Mazda 3 has been known to experience rust issues, potentially compromising the vehicle's structural integrity.
  • Why It's Worse: The 2015 model's subframe might not have had as robust anti-corrosion treatments as later models, making it more prone to rust, particularly in regions where road salt is heavily used.

While rust issues are not unique to the 2015 Mazda 3, certain design and material choices make this model year more susceptible to rust in specific areas, particularly the wheel arches, undercarriage, door edges, roof near the windshield, and the front subframe. These issues are more pronounced compared to some earlier or later Mazda 3 models, making it crucial for 2015 Mazda 3 owners to take proactive rust prevention measures.

Lanoguard has been designed for yearly/seasonal applications. It should be topped up at least once a year to ensure continuous protection. Although due to the simple application process there’s no harm in doing an Autumn & Spring application! The product is broken down by UV, so the more it is exposed to sunlight the shorter its life span. Inside box sections or inner chassis for example, it will last longer.

The general rule of thumb is that a little Lanoguard goes a long way, 1.5L of moto spray per application. – is ample coverage for vehicles such as Land Rovers and Pick Up trucks any vehicles over this size we would recommend more than 2L. Click here to look at our range.

Preparation is very minimal - all you need to do is jet wash your vehicle removing any dirt and grime. Make sure you remove any flaking or loose bits of rust, paint or underseal. Sometimes a wire brush can be used if needed to remove flaking bits. Ensure the vehicle is dry before you apply Lanoguard – it doesn’t have to be bone dry, as Lanoguard will displace moisture to an extent, but ensure you do not apply to a dripping wet surface. See our how to apply page here.

Lanoguard is great for chassis with surface rust. It has a natural affinity to ferrous metals and will bond to the metal underneath any surface rust, it acts as a barrier by hermetically sealing to the surface keeping oxygen and water out - stopping any rust from developing further.

Yes, you most certainly can. Lanoguard works fine with almost all sprayers, compressors, and applicators. You may find that it uses slightly more product than our trigger sprayer applicators will, but you’ll still get a nice even coverage of Lanoguard which will protect well. We do have a range of sprayers and applicators available on our accessories page.

Lanoguard reaches its final state around 7 to 10 days after application. Day 0 it is “oily” day 3 “soft” and final state is dry to the touch, but you know something is there. Like a candle to feel. Maybe a little softer. It dries to a clear / transparent semi satin wet look and stays that way for some months eventually dulling a little. But always stays clear; and of course, you can jet wash it to clean it back to how it was when you put it on. It is best to not drive the vehicle for 24hours to let it get through the first part of the curing process.

Lanoguard is eco-friendly and has green non-hazardous certifications. It does not require special handling, protective clothing or disposable gloves, which all add to the carbon footprint of utilising a product that is hazardous. The primary ingredient of Lanoguard is Lanolin which is a very ecologically safe and sound base. In fact, an entire dam in New Zealand was moved down river on a base of Lanoguard marine grease which shows you how the river authority was not concerned about any toxins that would be left as a result.
