Size:2 Ounce 2 tablespoons will coat 4 square feet of clean steel or aluminum! Rust Freeze is different from any other rust inhibitor because it can reach places that no other rust inhibitor can. Rust Freeze has the consistency of water and it loves corrosion! Because Rust Freeze is so thin it will seep into small places such as folded seams on sheet metal, overlaps that are spot welded, areas behind braces and inside tunnels and tubes. In fact Rust Freeze loves rust and corrosion so much it will âcreepâ its way through corrosion seeking it out sometimes traveling several inches into the corrosion on its own. Rust Freeze penetrates deep into the metal. On bare metal or heavily corroded aluminum or steel Rust Freeze will encapsulate the corrosion and then penetrate up to 2 mill into the base metal matrix, locking out air and preventing corrosion. Rust Freeze provides unparalleled corrosion protection on clean bare metal or corroded surfaces equally well! Even heavily corroded surfaces are protected simply by applying Machinists Mate Rust Freeze directly over the rusted/corroded surface, no need to grind the rust off! Rust Freeze will penetrate deep, encasing the corrosion all the way to the base metal surface sealing the entire surface and penetrate up to 2 mils into the grain of the base metal. Rust Freeze is a binary (two part) system. When Part A and B are mixed together Rust Freeze has the consistency water. Rust Freeze is easy to apply, simply brush, roll, wipe, dip or spray on. Rust Freeze prevents corrosion by preventing the metal from coming in contact with air or other corrosive elements. A small amount of Machinist Mate Rust freeze will go a very long way. Coverage is up to 2000 square feet per gallon of Rust Freeze! 8 ounces will cover up to 125 square feet of clean smooth non rusted steel!
