The Process

Being a Dinitrol Approved Treatment Centre we follow a strict procedure outlined by Dinitrol and are subject to unannounced visits to ensure that we are following the correct procedures and processes. We pride ourselves on carrying out a thorough service to ensure that you drive away happy.

Cleaning

Firstly the vehicle is pressure washed underneath using our dedicated spray off ramp – this removes the majority of the lose dirt and debris under the vehicle.

The vehicle is then put up on jacking beams, the wheels are removed and any wheel arch liners removed. The vehicle is then steam cleaned which removes any grease and oily deposits. This means that the product will stick fast and hard to the underside of the vehicle.

Rust Removal

After this the vehicle is left to dry. Compressed air is used to force air out of any cavities which may be harbouring hidden water. We have a special high volume fan which is used to speed up the drying process.

Next the vehicle is cleaned up with a combination of abrasive wheels or hand tools and a strong degreaser.

We categorise the preparation of each vehicle as follows:

Red – Very poor condition. 5+ hours preparation required. Heavy surface rust.

Amber – OK condition. 3 – 5 preparation required. Moderate surface rust.

Green – Good condition. 1 – 3 hours preparation required. Minor surface rust.

The vehicle is masked up for spraying to prevent any over spray reaching the paint work

Dinitrol RC800 or Dinitrol RC900 is applied at this stage to any areas which are actively corroded. This goes some way to reverting the damaged metal back to good strong metal. This product takes between 24 and 6 hours to cure.

Protection

The next stage is internal chassis protection or sill protection if your vehicle is of unibody design. Dinitrol ML is an oil based produced and is applied to the inside of the chassis using a 360 degree lance. This is left to dry before the next stage is started. Some customers also opt to have this products applied to the inside of their doors, bonnet and the bulkhead of Land Rovers. (You can specify if this is something you would like to have done when filling in the form for an estimate on our Contact Page.)

The main component of the Dinitrol family of products is then applied. The Dinitrol 4941 is then applied over all surfaces to be protected.

 

On some high impact areas, a high strength Dinitrol 445 or 447 application is applied to protect against for example stone impact in wheel arches.

The bulk of the protection is now completed. This is left to dry before a final check of the application and the vehicle is reassembled.

Photographs are provided at all stages of the process so that progress can be tracked. These are uploaded to the SWRP website upon completion and are provided to you via a secure link. A certificate is issued with the completion of the process which will help with resale value. You can view a sample of the link here.

After a final QC check, the vehicle is reunited with it’s owner.

This process is estimated to take 3 days. A free manual courtesy car can be provided as part of the service. Whilst your vehicle is with us, we can also offer servicing, MOT’s, upgrades and repairs.

If any repairs are needed prior to the rust proofing treatment being applied, these can be quoted for separately. We offer welding and fabrication services.
