How does the Must for Rust remove
rust?
the Must for Rust, because it is a low-viscosity liquid, penetrates into
every void of a metal surface and dissolves the oxidation through
chemical action. Then tiny elements (sometimes seen as white crystals)
are formed and become integral with the surface molecules of the metal
to resist rusting again. The corrosive agents attack these crystals
rather than the metal. These crystals become part of the metal surface
and need not be removed for any painting or subsequent operations, such
as welding, machining, etc. There is no 'build' as with a paint film,
and they are completely inert and do not react with any solvent or
vehicle that is found in paints, coatings, and so forth. No gassing
occurs with heating.
How do I neutralize it?
the Must for Rust doesn't need to be neutralized on the metal surface.
Once it dries, it becomes inert and won't react to temperature or other
chemicals.
How long does it take to remove rust?
That's difficult to answer. the Must for Rust cleans most medium to
light rust in 15-30 minutes. Variables include temperature, corrosion
level of the metal surface and type of metal. the Must for Rust works
faster at warmer temperatures on good quality ferrous and non-ferrous
metals. Corrosion on some non-ferrous metals like copper, bronze and
aluminum is removed in less than five minutes. Metal alloys heavy in
iron can sometimes take more than 30 minutes if the surface is heavily
pitted.
Will it hurt the paint?
the Must for Rust is water based and contains no solvents, so it won't
remove or penetrate paint. If rust is present under a coating, the
coating must be removed through mechanical methods before the Must for
Rust can go to work. Still, if the Must for Rust overspray is left to
dry on paint, it can sometimes lighten the color through the process of
de-oxidation of the paint surface. To prevent this, simply wipe excess
the Must for Rust off painted surfaces after applying the Must for Rust
to the rusted area.
Do I have to wash it off?
No, if you wash the Must for Rust off after dissolving the rust, you're
using it just as a rust remover and not as a rust inhibitor. As the Must
for Rust dries on the surface of the metal, it protects against the
formation of oxides. The only time rinsing is recommended is to wash off
dirt or foreign matter after the rust is dissolved. Rinsing is also
recommended for some non-ferrous metals.

Can I paint over the Must for Rust?
Yes. When dry, the Must for Rust accepts any primer, paint, coating,
plating, welding, etc. Painting over the Must for Rust has two benefits.
The first is that the Must for Rust provides a clean surface free of
contaminants which allows a secure bond for coating. The second is that
when chips or breaks appear in the coating, the Must for Rust underneath
the coating will limit the rust to the break. That means that rust won't
spread under the
coating and maintenance touch-ups will be quicker and easier.
Do I have to remove it before welding?
No. the Must for Rust helps weld joints last longer. Coatings applied to
welds tend to suffer premature failure because the heat of welding has
formed oxides that are not removed by hand or mechanical cleaning.
How far does it go?
That depends on how the Must for Rust is applied. When sprayed, one
gallon of full strength the Must for Rust can cover 500 square feet.
When brushed, 300 square feet. When used in a dip operation, the Must
for Rust can last for months, depending on the type of rust and metal
cleaned. Eventually, the the Must for Rust in the tank will become
contaminated and it's rust removal ability will decrease.
How do we remove the white deposit?
If the solution is too strong, white inhibitive crystals will appear
after drying. To remove these, simply apply the Must for Rust, then wipe
from the surface. Once dry, the the Must for Rust treated surface is
completely inert and does not react with any solvent or paint pigment.
When you have sampled correctly and determined the dilution required,
there will be no excess of unused chemicals and no neutralizing needed.
How do we achieve optimum results?
 |
Make sure the metal
surface is clean of grease and oil. the Must for Rust is
water based, and can't remove rust if oil is present.
|
|
|
Keep the surface wet
with the Must for Rust. When the Must for Rust dries, it
stops working. As long as the surface remains coated
with liquid the Must for Rust, the rust will be
dissolved.
|
|
|
Work in a warm
environment. If the Must for Rust can't be heated, try
to apply in ambient temperature of 70 degrees or above.
|
|
|
When painting on clean
metal surfaces, spray a 50% diluted solution on the
surface and let dry before painting.
