However, even such a car eventually develops problems with body parts, especially with the rear fenders. They are susceptible to corrosion, mechanical damage from an accident or bad parking, and also suffer from aggressive reagents on winter roads.

In this article we will look at everything you need to know about rear fenders. Octavia A5: From choosing between original and aftermarket parts to step-by-step instructions for replacement and painting. You will learn how to save on repairs without losing quality, what tools are needed for the job, and what typical mistakes allowed by car owners for self-repairs. We will also analyze prices on the market and give recommendations on anti-corrosion treatment.

Original vs. non-original rear fenders: what to choose?

The first question that arises when replacing a rear wing is whether to buy original part from Škoda or find an analogue from third-party manufacturers. Original fenders guarantee a perfect fit and connection with the body, but their price may be unaffordable for your budget. For example, a new rear wing from an official dealer will cost 15,000–25,000 rubles (depending on the side and configuration).

An alternative is non-original parts from trusted brands:

• 🔹 Febi — German quality at an average price (RUB 8,000–12,000). Good geometry, but sometimes requires adjustment.
• 🔹 Hella — a reliable manufacturer, parts are often used in service centers (RUB 10,000–14,000).
• 🔹 Polcar - a Polish brand with budget offers (5,000–9,000 rubles), but the quality of the metal may be inferior to the original.
• 🔹 Kits (for example, from AutoVAZ or Chinese suppliers) are cheap (RUB 3,000–6,000), but the risk of defects and corrosion is higher.

When choosing an analogue, be sure to check:

• 📌 Compatible with your year of manufacture Octavia A5 (2004–2013).
• 📌 All mounting holes and cutouts for lights are present.
• 📌 The thickness of the metal (for the original - 0.8–1 mm, for cheap analogues it may be thinner).

⚠️ Attention: If you buy a fender after an accident, make sure that it has not been previously painted - traces of rust or damage may be hidden under the layer of paint. Ask the seller for a photo of the back of the part.

• 🔨 Welding machine (semiautomatic or inverter).
• 🔨 Grinder with cutting wheel (125 mm).
• 🔨 Drill and drill bits for metal.
• 🔨 Set of wrenches and sockets.
• 🔨 Safety glasses and gloves.
• 🔨 Anti-corrosion mastic (for example, Dinitrol or Tectyl).

Stages of work:

1. Removing the old wing.
   • Disconnect the battery terminal.
   • Remove the rear light (unscrew the 3 bolts from the inside of the trunk).
   • Mark the cut lines with a marker (if the wing is welded).
   • Carefully cut off the welds with a grinder without touching the body.
2. Preparing a new wing.
   • Try on the part and adjust the fasteners if necessary.
   • Clean the welds on the body and fender.
   • Apply primer to bare metal areas.
3. Welding a new wing.
   • Grab the wing at 3-4 points and check the gaps.
   • Weld the seams with a continuous seam (2–3 cm increments).
   • Sand the seams with a sander.
4. Anti-corrosion treatment.
   • Apply mastic to the inner surface of the wing.
   • Treat the welds with sealant.

⚠️ Attention: When welding, do not overheat the metal - this may deform the wing or damage the paintwork of adjacent panels. Use spot welding intermittently for cooling.

After replacing the wing, be sure to check:

• 🔧 The performance of the rear light (the contacts may have oxidized).
• 🔧 The gaps between the fender and the trunk/rear door (must be uniform).
• 🔧 Tightness (after washing there should be no leaks into the trunk).

Painting the rear wing: technology and tips

Even if you installed a new fender, it will not last long without high-quality painting. Painting technology includes several stages, each of which is important for the longevity of the result. Let's look at the process using an example Octavia A5 taking into account its body features.

Materials and equipment:

• 🎨 Primer (epoxy or acid).
• 🎨 Paint (select according to your car's color code).
• 🎨 Varnish (two-component for durability).
• 🎨 Putty (polyester for deep dents).
• 🎨 Compressor and spray gun (pressure 2–2.5 atm).

Step by step process:

1. Surface preparation.
   • Degrease the wing with white spirit or anti-silicone.
   • Fill dents (if any) and sand with sandpaper P120–P240.
   • Apply primer in 2-3 layers and dry.
2. Painting.
   • Apply a base coat of paint (2-3 layers with drying time between coats for 10-15 minutes).
   • Apply varnish (2 coats) for protection and shine.
3. Polishing.
   • After drying (24 hours), polish the surface with paste 3M or Farecla.

Paint color for Octavia A5 selected by code, which is indicated on a plate in the trunk or under the hood. Popular colors:

• 🔴 LA5W — Candy White (white).
• 🔵 5G5G — Race Blue (metallic blue).
• ⚫ U7U7 — Magic Black (black mother-of-pearl).

How to check the quality of painting?

Once dry, inspect the wing from different angles under bright light. High-quality painting should not have:

- bubbles or craters,

- varnish drips,

- differences in shade with neighboring panels.

If you notice any imperfections, sand again and reapply varnish.

Rear wing repair without replacement: when is this possible?

Damage to the rear fender does not always require a complete replacement. In some cases you can get by local repairs, which will save time and money. Let's consider in what situations this is justified:

Types of repair:

• 🛠️ Straightening dents. Suitable for shallow damage without tearing the metal. Method used PDR (paintless dent removal) or traditional straightening with heating.
• 🛠️ Welding cracks. If the wing is cracked but not deformed, the crack can be welded and puttied.
• 🛠️ Local painting. In case of scratches or chips, it is enough to clean the damaged area and touch up the paint.

When repair is not possible:

• 🚫 Severe deformation (the wing “collapsed” after the impact).
• 🚫 Through corrosion (holes in metal).
• 🚫 Damage to the fastenings to the body.

Service repair cost:

• 💰 Dent straightening - from RUB 3,000.
• 💰 Welding a crack - from 5,000 rubles.
• 💰 Local painting - from 7,000 rubles.

⚠️ Attention: If the wing was repaired after an accident, be sure to check the geometry of the body on the stand. Even a slight misalignment can lead to problems opening the trunk or uneven tire wear.

Anti-corrosion treatment: how to protect the wing from rust?

Hind wings Octavia A5 Particularly vulnerable to corrosion due to constant exposure to dirt, water and reagents. To extend the life of a part, it is necessary comprehensive anti-corrosion treatment. Let's consider effective methods:

Types of protection:

• 🛡️ Mastic. Applied to the inner surface of the wing. Popular brands: Dinitrol ML, Tectyl 506.
• 🛡️ Liquid plastic. Forms an elastic coating that is resistant to impacts (e.g. Noxudol 700).
• 🛡️ Galvanization. Long-term protection, but requires professional equipment.

How to apply anticorrosive:

1. Thoroughly clean the surface from dirt and rust (use a metal brush or sandblast).
2. Degrease with white spirit.
3. Apply the anticorrosive agent in an even layer (for mastic, use a brush or spray).
4. Dry (time depends on the type of composition - from 2 to 24 hours).

Recommended processing frequency:

• 📅 Mastic - once every 2-3 years.
• 📅 Liquid plastic - once every 5 years.
• 📅 Galvanization - once every 10 years (provided the coating is intact).

Typical mistakes when working with the rear wing Octavia A5

Even experienced car owners make mistakes when repairing or replacing rear fenders. Here are the most common ones misses and how to avoid them:

Mistake 1: Skimping on preparation.

• 🔸 Do not clean the rust down to the metal before welding → corrosion will continue to spread under the new wing.
• 🔸 Welds are not primed → the metal quickly rusts.

Error 2: Incorrect welding.

• 🔸 Using too much current → burning through the metal.
• 🔸 They don’t check the geometry after tacking → the wing is crooked.

Mistake 3: Poor quality painting.

• 🔸 Paint without primer → paint peels off.
• 🔸 The temperature regime is not observed → the varnish becomes cloudy.

Mistake 4: Ignoring anticorrosion.

• 🔸 The inside of the wing is not treated → rust from the inside.
• 🔸 They use cheap mastics → protection lasts less than a year.

⚠️ Attention: If after replacing the wing there is creaking When opening the trunk, most likely the problem is an incorrect installation of the seal or a skewed hinge. Do not delay diagnostics - this may lead to deformation of the new part.
