GEM RUST KILLER & METAL PREP
is a balanced formula of phosphoric acid, wetting agents and extenders. It chemically
changes iron oxide (rust) to iron phosphate, forming a tough undercoating which inhibits
re-rusting. Paint can then adhere so closely to the metal preventing moisture and oxygen
from attacking the surface, thus resulting in a much longer enduring paint job. It is a
rust-inhibiting coating, NOT A PAINT. Surfaces should
be top coated after treatment. Even without painting, metal cured with
GEM RUST KILLER & METAL PREP and kept indoors
is protected from further rust for a period of several months. This reduces the urgency
for immediately painting the metal. A cured surface which is rinsed or exposed to rain
often turns a light gray color, excessive dew and humidity may prolong drying time and
produce a powdery build-up. PREPARATION: You can use chemical paint strippers, a sander, or grinder to remove the paint. Sand blasting and bead blasting may also be used. |
APPLICATION:
Cover surface with GEM RUST KILLER & METAL PREP directly
from the container using a plastic sprayer and a scuff pad. Always use new clean pads to avoid
contamination. Apply GEM RUST KILLER & METAL PREP directly
onto the scuff pad. Do not spray product onto the panel itself
because it may mist onto other previously cleaned areas and contaminate them. Spray it into the
scuff pad while moving the nozzle against the pad slowly. Scuff with moistened pad one square foot
area, in circular movements until surface appears clean of rust. For best results, use at
temperatures between 65 and 90 degrees Fahrenheit. If the temperature is hotter the product will
dry much quicker and you may have to reapply it during the process. It is best in hotter regions
to do this in the cooler hours of the morning. Gem Rust Killer & Metal Prep does not need to be
rinsed. |

GALVANIZED: For light rust cover area and allow to dry. Repeat application if rust is still evident. For heavy rust use repeated applications, keeping the surface wet until rust softens before allowing to dry. After thoroughly dry, inspect to verify there are no signs of rust remaining. Repeat if rust is still evident. LET DRY OVERNIGHT. Remove any loose powder and apply oil-based paint. Where appearance is important, apply one coat to etch metal. Wipe to a smooth finish, let dry, then paint. CHROME: Apply full strength, keep wet until rust softens, wipe with clean cloth, and allow to dry. Apply auto wax immediately. CAUTION: Contains phosphoric acid. Use in well ventilated area, suitable precaution should be observed (such as wearing rubber gloves, goggles and protective clothing) when handling product. Avoid contact with eyes and prolonged contact with skin or clothing. Do not swallow. For spray mist use NIOSH/MSHA acid respirator with face piece. During severe exposure, use self-contained breathing apparatus. FIRST AID:
