Vactan showed a
time saving of 25% over the Trustan and 40% over a similar
competitive product due to there being no need to wash down
before painting or any need for a priming coat before the
undercoat and finish coat.
Sample test
plates from a single sheet of rusted steel were prepared, using
all three products without any supplementary paint coatings and
left outside for 12 weeks over the Winter period. At the end of
the test period, surface rust had appeared on the plates treated
with Trustan and the other coating, but up to the present, 20
weeks after application, no rust has appeared on the surface
treated with Vactan.
RECOMMENDATION.
That Vactan now become the specified product as the rust
treatment for use on general Army equipment prior to painting,
since it is excellent for both large areas and spot treatment.
