How much does it cost to undercoat a jeep wrangler?

A jeep is an off-road vehicle for many. It is purchased by most people to take it off-road into rough terrain, especially for a safari tour. Therefore, any vehicle taken into the forest has a greater risk of suffering damage.

Keeping this in consideration, a jeep is built tough. With its big tires and heavy body, it is built to make it perfect as an off-road travel vehicle, especially for rough terrain. However, this also means that one needs to keep it in good condition and take it for regular maintenance to prevent rusting and corrosion.

What is jeep undercoating?

Undercoating your vehicle means applying a protective layer of non-corrosive and abrasion-resistant material to its underside. This will protect it from rusting and corrosion by debris and hitting by rocks. The best time to undercoat is when the vehicle is new. This is because at that time there is no corrosion or rust and applying the protective layer will keep it corrosion free for years to come.

Cost of undercoating your jeep:

The cost of undercoating depends on several factors, the first and foremost being the extent of undercoating required. It can cost you as low as $150 to as high as $2500.

If your jeep only needs a regular coating, it can be done for under $500 and you can also do it yourself without hiring a professional. However, if there is excessive corrosion and rust which needs to be removed and treated first, the cost of undercoating will go up to around $2500.

Undercoating cost influencing factors:

Several factors influence the final cost of undercoating your vehicle. These include:

  • Type of undercoat.
  • Model of vehicle.
  • Need to hire a professional.
  • Presence of rust and corrosion.
  • Age of the vehicle when undercoating (this determines the rust and debris present).
  • Type of package chosen.

Types of jeep under coatings:

Hard undercoating:

This includes the hard wax or the rubberized wax undercoating. However, one needs to remove the rust before applying the coat otherwise the oxidation continues and so does the rusting. However, if this is applied properly it will protect against abrasion or damage without chipping for years.

Soft undercoating:

This type of undercoating can only be applied if there is no rust which means that your jeep is new. Therefore, when you buy the jeep and apply the soft undercoat properly, it will go a long way without chipping. A proper undercoat means that folds, spots, and welded areas are all properly covered and there is no place for moisture to get trapped and rusting to start.

Rubberized undercoating:

Apart from quick-drying, it is clean and easy to apply. After drying, it leaves a rubber-like texture. It will provide your vehicle protection from moisture, rust, dings, and dents.

Asphalt-based undercoating:

This is one of the best options for undercoating. The fact this it is unpaintable makes it suitable only for undercarriages. However, manufacturers add bits of rubber-like material to it which give it the properties of corrosion resistance and help in noise reduction.

Polyurethane undercoating:

This undercoating is effective in sealing cracks and seams. It protects unoxidized metal from rusting by displacing moisture and salt. It has the advantage of easy application by loading into an application gun. However, the surface needs prepping before application. This includes; degreasing and application of an etching primer to the bare metal surface.

Wax or paraffin-based undercoating:

The wax or paraffin-based undercoats have an easy application but they are not very durable and require re-application within a few months due to the inability of wax to stick to metal. It also protects against moisture due to its ability to seep quickly into cracks and seams.
