What is the 911 Porsche Chassis Undercoating Process

June 16, 2018

 

 

 

Rustproofing and undercoating your Porsche can protect it from corrosion and rust. This is especially important for the undercarriage of your vehicle, which commonly comes into contact with substances such as water, chemicals such as salt, and other dirt and debris from the road. Without some sort of protection, the bottom of your vehicle can rust and corrode, leading to part failure. Before rustproofing or undercoating your undercarriage, you need to consider a few things.

 

The advantages and disadvantages of rustproofing/undercoating your vehicle
 

The best time to rustproof or apply undercoating protection is when you buy a brand new vehicle that hasn't been driven yet. However this isn't the case for early Porsche owners, which leaves to discuss  the alternative option.  

 

Applying an undercoating on a used vehicle.

 

This is the alternative  to having an undercoating applied at the dealership.  This simply means applying the it at a later time. While the underside of the vehicle has already been exposed to water, dirt, and other debris from the road at this point, applying an undercoating now can protect it from further exposure.

 

Different types of rustproofing/undercoating

 

When having your vehicle rustproofed or an undercoating applied, you have a few options to choose from. Whether you prefer the latest technology or a more tried and true method, knowing what the different options are should allow you to choose the best one for your vehicle.

 

Electronic method.

 

Using a weak electric current, this small device can stop the corroding effects of rust. You can have these electronic devices installed at the dealership, or save some money and buy them from a source outside of the dealership. The reviews on these devices are mixed, as this is a virtually new technology.

 

Undercoating.

 

This method involves spraying a tar-based substance on the exposed parts of a vehicle's underbody.

The tar-like undercoating acts as a barrier once it hardens, keeping out moisture, salt, and other substances.

This undercoating works best when applied to the undercarriage of a new vehicle. It also requires expert application, or it can crack, letting in moisture.

 

Dripless oil spray

 

A wax-like substance applied to the entire body of the vehicle, it hardens once it has dried. One of the downsides of dripless oil sprays is that you need to have holes drilled into the body of the car at specific points to make it effective.

The spray also has a high viscosity, meaning that it does not always get into all of the nooks and crannies of your vehicle.

 

Drip oil spray.

 

This is the most commonly recommended rust protection.

Drip oil sprays tend to continue to drip once applied until they dry. This dripping can last anywhere up to 48 hours after application. Unlike the dripless varieties, the more watery nature of drip oil sprays means it gets into more areas on your vehicle, though you still need to have holes drilled in your vehicle's fenders, doors, and other areas to make sure that it gets to all the areas it needs to.

 

Undercoating can be done by yourself and there are resources with instructions available, but if you do not have the right equipment or enough space, it can be a risk to your safety so if the budget allows, hire a professional.
