DINITROL 449 – 1 Litre Canister

From: £26.38

Vehicle bitumen based underbody and stonechip coating

DINITROL 449 is an environmentally friendly black coloured bitumen based underbody and stonechip coating with good corrosion protection and sound deadening properties. After curing DINITROL 449 has a very durable tough and elastic film, which results in a very good stonechip resistance. The product is NOT overpaintable please see additional information below. DINITROL 449 is applied mainly in the automotive aftermarket with cars, buses & trucks. The waterborne underbody coating provides extra strong corrosion prevention and changes colour when drying once applied.

Did you know that DINITROL 449 and DINITROL 977 can be used together to form a comprehensive water borne corrosion protection system application. Rather than applying both products separately, we recommend a two-layer application method with DINITROL 449 and DINITROL 977. This unique combination is very effective on surfaces that are already corroded.

Please note: This product is NOT over paintable

(1 x 1 Litre can supplied or 12 if the full box is purchased)
