Workshop Pro MD4 is an effective, damp start and penetrating fluid with
outstanding corrosion protection properties. When applied to wet parts
the chemistry of MD4 has a powerful attraction to the underlying
surfaces and this completely displaces traces of water. Therefore this
product is particularly useful as an engine damp start.
Using the aerosol version, a short spray on to the affected parts will
displace any wetness and prevent voltage breakdown, allowing the engine
to be started again normally. MD4 is also an effective penetrating fluid
for freeing all seized and corroded metal parts. It has been designed
with a very low surface tension, which gives it excellent penetrating
power, and this, coupled with superior solvent and lubricating
properties enables the most inaccessible corroded parts to be speedily
dismantled. The residual oil film acts as a rust and corrosion
preventative on the disassembled parts and helps reassembly.
