How do I apply Dinitrol rust protection to the underbody of car?

Posted on

As I headed off for work early this morning I felt a definite damp chill in the air. That time of the year has approached when it is easy to retreat into the warmth of our homes. But, for our vehicles there is no hiding away from the cold, rain, mud and salt gritted roads. Unless, of course you store your vehicle away for the winter.  

The winter conditions in the UK are not as severe as that in Northern Europe and Scandinavia. This has resulted in car owners being a lot less diligent about re-applying rust protection to the undercarriage of their ageing vehicle. In fact many of us don't even check for signs of corrosion.

Rust protection application to the underbody, particularly of older vehicles should be done every 2 to 3 years We recommend rust proofing with Dinitrol 4941 underbody wax - it is bitumen based providing excellent abrasion resistance performance and self-healing. Available in aerosol for DIY applications or where small areas need added rust protection. Also available in 1 litre Schutz style threaded neck canisters for attachment with a compatible air supply and compressor.

Corrosion preventive coating which provides long term resistance against corrosion and abrasion, even under extreme conditions.
Dries to a tough elastic waxy protective coating giving a high degree of rust protection.

How to apply Dinitrol 4941 rust protection wax

  • The spray can has to be used at room temperature. (16− 25°C)
  • Shake spray can until the steel mixing balls can be clearly heard.
  • Apply to surfaces free from corrosion, dust and grease.
  • Recommended spraying distance is 20-30 cm.
  • To ensure an optimal rust protection apply a wet film thickness of 600− 900 μm.
  • Thicker layers can be applied in separate steps.
  • Allow the material to dry for at least 15 minutes between the applications.
  • Leave to dry at room temperature.
In order to prevent blocking of the nozzle, turn the can up-side down and empty the pipe.
After a few seconds, only gas will come out, then stop spraying.
