Metal Prep. Expert mechanic and car restorer Barry Wilson usually relies on a sand blaster to remove rusty spots when fixing up a classic car, but he relies on POR-15 Metal Prep when the rust is ...
Special kinds of primer (rust-converters) can be used to chemically convert rust to the solid metal salts. [7] This process is not recommended for structural steel. Painting and gluing aluminum are especially important in the aircraft industry, which uses toxic zinc chromate primers and chromating to add the necessary adhesion properties. In ...
Structural rust (affecting structural components which must withstand considerable forces) should be cut back to sound metal and new metal welded in, or the affected part should be completely replaced. Wax may not penetrate spot-welded seams or thick rust effectively. A thinner (less viscous) mineral-oil-based anti-rust product followed by anti ...

[2] The tool is used in metalwork applications as diverse as home repair, automotive repair, and shipboard preservation. [3 ...
Rust converters are chemical solutions or primers that can be applied directly to an iron or iron alloy surface to convert iron oxides into a protective chemical barrier. These compounds interact with iron oxides, especially iron(III) oxide , converting them into an adherent black layer ( black oxide ) that is more resistant to moisture and ...
To get a regular paint to look smooth, the surface would have to be prepared first, for example, by spackling, sanding, grinding or polishing. With hammer paint, this step can be omitted. Some hammer paints (e.g. by Hammerite) are formulated to be usable directly on rusted steel without surface preparation other than brushing to remove the ...
