Ask The Mechanic – Dinitrol for T4, T5, T6

Dinitrol Guide For Modern
Transporter Types
12345
In the last issue, The Mechanic looked at
Dinitrol products and how to use it with classic
transporter models. For those of you that own
a modern Transporter, here is a guide for T4, T5
and T6 models.
Dinitrol is an oil based product that contains
rust inhibiting ingredients to treat and stop rust
after it has been applied. It also forms a barrier
that prevents further corrosion occurring.
Dinitrol is supplied in several different forms,
a cavity wax for use in inner sills etc. and an
under body wax that dries to a flexible tough
film to withstand rain and salt.

Due to modern manufacturing techniques,
the later range of Transporter is less prone
to rusting, but like all Volkswagens they will
eventually fall prey to the dreaded rust bug.
Although treated with rust protection from
new, it is recommended that this is maintained
and renewed after several years of use. As with
the earlier Vans, converting these into Campers
creates the added problem of moisture
generated by cooking etc. Again, removal of
the interior and inner trim is the only way to
get a comprehensive finish. Treating a newer
Van will help preserve it for the future and can
add to the resale value at a later date.
