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 overpaintable please see additional information below.

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.

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