Underseal, black (Spray)

Clean the surfaces to be treated thoroughly in advance and remove rust. The surfaces must be dry and free of wax, dirt and grease and largely free of dust.

Shake well before use! When the ball has worked loose, continue to shake the can for another minute. Hold the can vertically when spraying and apply the contents thinly from a distance of about 20 – 30 cm. The resistance to abrasion and corrosion increases with increasing coating thickness. For this reason, the spraying process should be repeated once or twice after a short flash-off period. Should be sprayed using a cross pattern to avoid spray shadowing. Can be painted over after approx. 60 – 90 min. (depending on film thickness, temperature and humidity). Most of the usual water and solvent-based 2C paints and base coats can be used here. When using a 2C paint, we recommend using a coat of plastic primer first and painting over this coat after it is completely dry, as recommended by most paint manufacturers.

Recommended application temperature: 15 – 25 °C

We recommend applying thin coats. Depending on the desired layer thickness, intermediate drying should be carried out after each layer. If the stoneguard is subsequently painted over, the coats will become increasingly hard. In other words, the treated surface should be treated accordingly with adhesive primer for plastics in the same way a plastic surface would be.

After use, the can should be inverted and sprayed until the valve is clear and only propellant escapes!

Do not spray material onto moving parts and hot components such as mechanical joints, the engine, gearbox, drive shaft, exhaust pipe, catalyst and brake systems.
