It chemically changes iron oxide (rust) to iron phosphate, forming a tough undercoating which inhibits re-rusting. Paints 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  \nrust-inhibiting coating-NOT A PAINT. Must be top coated. 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.  \nPREPARATION: You can use chemical paint strippers, a sander, or grinder to remove the paint. Sand blasting and bead blasting may also be used.  \nAPPLICATION: Cover surface with Gem Rust Killer & Metal Prep directly from the container using a plasticsprayer 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 toreapply 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.  \nIf you follow these directions correctly you do not have to wear a mask because none of the acid is being sprayed into the air. It remains a liquid so it shouldn’t cause any breathing problems, however for your own safety you may want to wear a mask, goggles and gloves.  \nDE-RUST WITH ACID BATH: Use plastic container only. Fill container with full strength GEM RUST KILLER &  \nMETAL PREP.  \nParts must be free of any oil or dirt. Submerge parts in bath. A chemical reaction occurs resulting in a “boiling”appearance. Keep a close eye on thin steel parts that can be eaten away. Mild rust vanishes in 10 to 20 minutes when exposed to fresh acid. Heavier rust takes longer, even to being soaked over night.  \nGALVANIZED: 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.  \nCHROME: Apply full strength, keep wet until rust softens, wipe with clean cloth, allow to dry. Apply auto wax immediately.  \nCAUTION: 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 or prolonged contact with skin or clothing. Do not swallow. For spray mist use NIOSH/MSHA acid respirator with full face piece. During severe exposure, use self-contained breathing apparatus.  \nFIRST AID: For eyes, flush with cool water for 15 minutes then get prompt medical attention. If swallowed rinse mouth. DO NOT induce vomiting, give several glasses of water or milk and call physician. For skin, flush with cool water. If irritation persists, get medical attention. If inhaled move into fresh air. Wash contaminated clothing before reuse.  \nRead Safety Data Sheet ","cbCailS39Xc3JbpC","https://ap.wps.com/l/cbCailS39Xc3JbpC","pdf",316604,"English","# Preparation\n## Surface Prep and Application\n## De-rust With Acid Bath\n## Galvanized and Chrome Procedures\n# Caution and First Aid\n## Handling, Ventilation, and PPE\n## First Aid Steps","[{\"question\":\"What does Gem Rust Killer \\u0026 Metal Prep do to rusted metal surfaces?\",\"answer\":\"It chemically changes iron oxide (rust) into iron phosphate, creating a tough undercoating that inhibits re-rusting and helps paint adhere closely to the metal.\"},{\"question\":\"How should Gem Rust Killer \\u0026 Metal Prep be applied after preparation?\",\"answer\":\"Cover the surface directly from the container onto a scuff pad using clean, new pads to avoid contamination.
