JLM Underbody Coating J04601 JLM LUBRICANTS

JLM Underbody Coating (UBC) is based on synthetic resins and rubbers, and has been developed for long-term gravel and rust protection.

Product information

JLM Underbody Coating is a fast-drying, waterproof, resilient, oversprayable, sound-insulating and noise-reducing layer that provides protection against damage caused by chippings, such as gravel, grit salt or dirt. It also prevents rust and damage to vehicle underbody components, floor panels, wheel compartments, spoilers, doors, door sills and visible bodywork components.

JLM Underbody Coating is made from synthetic resin and hard (SBS) rubber, which means that it is durable, adheres well and dries rapidly. JLM Underbody Coating is thixotropic (pseudoplastic). This means that if you shake the can in which it is stored, the viscosity of the coating decreases, making it more liquid and therefore easier to apply by spraying. Once spraying is complete, the liquid immediately changes back into a gel. This enables it to be applied to the vehicle as a structured layer that adheres well to the underbody and forms a non-drip finish.


Use at room temperature. Stir before use. Surface must be dry and clean, free from dirt, rust, grease etc. Spray or brush an even layer on the object or surface to be coated. Recommended thickness = approximately 0,5 mm at application. Apply at least 2 layers Leave to evaporate/dry. Before overpainting allow the coating to be completely dried. Do not coat the exhaust, brake systems, or motor parts. For high corrosion protection bare metal should be treated with an anti-corrosion primer prior to the use anti gravel. Can be removed with aromatic solvents as white spirit, boiling point naphtha, xylene, etc. Application temperature 10 – 25 ºC.

These are the most common questions we get.

Do any of the JLM additives help the performance of the high pressure diesel fuel pump?

J02330 Rapid is perfect for pump and injectors!

Is it OK to use the JLM Extreme Clean and the DPF Cleaner together?

No, this will not have a positive effect. In fact it may cause an adverse effect. And also the risk of overdosing! Never combine fuel additives


Will JLM Bluboost dissolve existing crystal infestation or is it more like a preventative product?

JLM’s Bluboost additive cleans and prevents crystal formation in the AdBlue® dosing system. It also conditions the AdBlue® fluid for a longer time to ensure proper working of the AdBlue® and SCR system. This helps prevent performance loss and the often-subsequent expensive repairs. It also reduces foaming at low temperatures

Is the JLM Engine Oil Flush safe for use with wet belt engines?

Our JLM OIL FLUSH is safe to use with ‘wet belts’ (TBIO). This is mainly because we use non solvent and premium pack of oil cleaning additives.


Does the Petrol Emissions Reduction Treatment also clean the catalytic convertor?

The catalytic converter is not a filter, it functions by converting harmful emission gases into less harmful gases. The filter can become contaminated if for example there has been an oil leak, and when this happens the filter needs to be replaced. There is no additive or chemical that will remove physical contamination from a catalytic.
