How do I stop rust permanently with POR-15 Solutions?
4 Steps to stop Rust Permanently:
Step 1 : Degrease and Clean Surface 
Marine Clean cleans and degreases in one application without leaving residues, noxious fumes or flammable solvents. No other cleaner works as fast or as well. It makes petroleum-based cleaners almost obsolete because it can be diluted with water to 3, 4, 5 and even 10 times its volume while remaining even more potent than other cleaners. Marine Clean removes grease, oil, mildew, algae, musty odours, soap films, and wax. Use it to clean canvas, vinyl, nylon, holding tanks, grease traps, auto parts and more.
Before applying ANY rust preventive paint, you MUST remove any oily film or residue. Even if you’re fairly sure that your work piece is clean, hit it with Marine Clean to be absolutely certain of good adhesion.
Step 2 : Neutralize Rust and Etch Metal 
After thoroughly degreasing your work piece, apply environmentally safe, Metal Ready to both neutralize any rust, and etch any clean bare metal. This will allow better adhesion of POR-15 or any paint or coating. Metal Ready provides the best adhesion on any surface, including aluminum and shiny polished metal surfaces. The simple one-step process gently etches metal, creating an ideal anchor pattern for coatings, while simultaneously leaving a zinc phosphate film to promote chemical bonding of paint and steel. Avoid "rust conversion" products which may leave harmful residues that prevent proper adhesion of coatings. Metal Ready is not caustic, corrosive, toxic or flammable.
Step 3 : Apply Rust Preventive Coating on Surface 
Seal the rusty metal with POR-15 Rust Preventative Coating. As the moisture resistant coating of POR-15 bonds to the rusty metal, it will form an unbelievably tough, almost ceramic-like finish that will not crack, chip or peel.
Use POR-15 to coat a rusty frame, floor pans, farm equipment, underwater marine items, or even a heavily corroded battery tray.
The secret lies in the POR-15 curing process. Unlike ordinary "paints", POR-15 cures by drawing moisture from the atmosphere. Paint, on the other hand, cures through the process of solvent evaporation through pores (that's why you can smell a paint job for weeks). Those same pores allow microscopic amounts of air and moisture to gradually reach the surface of the painted metal.
POR-15 is so tough, that some folks describe it as "Powder coat in a can". Use it on your chassis, and you will be surprised as how little effect gravel roads have on the finish. In fact, offroad enthusiasts and dirt bike racers use it on their frames and under-carriage, where NO "paint" can survive. Furthermore, POR-15 is very flexible, and can withstand much twisting and bending without cracking.
POR-15 is sensitive to UV light (sun) and MUST be topcoated for prolonged exposure to sunlight. Topcoating is not required for areas not exposed to sunlight.
POR-15 is available in Clear, Grey and Silver.
Step 4 : Top Coat the Surface
Topcoat the metal surface with Chassis Coat Black, Blackcote
or Stirling Silver. They all have no sensitivity to UV light. They are highly flexible, non-porous, extremely scratch and chip resistant, and strengthened by exposure to moisture. 
Blackcote has a beautiful gloss black finish and is perfect for restoring the gloss black frames, chassis and underhood parts of earlier vehicles. 
Chassis Coat Black has a smooth, satiny semi-gloss finish, and is probably more "correct as original" for underhood and chassis components for cars produced in the USA from the early 1950's to today.
Stirling Silver has a medium-gloss silver appearance.
