POR-15 Metal Prep provides the best adhesion for POR-15 Rust Preventive Coating on any metal surface, including aluminum and shiny polished metal surfaces. The simple process of this pre-paint cleaner for metal gently etches metal, creating an ideal anchor pattern for coatings such as POR-15 Rust Preventive Coating, while simultaneously leaving a zinc phosphate coating to insure chemical bonding of paint and steel. Avoid other preps that may leave harmful residues which prevent proper adhesion. After thoroughly degreasing your work piece, apply environmentally safe POR-15 Metal Prep to both neutralize any rust and etch any clean bare metal. This metal etching solution will allow better adhesion of POR-15 Rust Preventive Coating or any other coating. This metal-etching rust neutralizer is not caustic, corrosive, toxic or flammable.

Features:

  • Easy-to-usemetal etching rust neutralizer – one step process
  • Coats metal with zinc phosphate
  • No harmful residues
  • Insures perfect paint adhesion
  • Is reusable
  • Provides perfect base for all paints
  • Removes surface rust in minutes

POR-15 Metal Prep Technical Data Sheet


Step 2 Prep it with POR-15 Metal Prep
"We located the rustiest car we could find and performed a complete floor pan replacement. The key to the repairs is etching the new metal with Metal Prep and sealing it with POR-15 and paint. This ensures that rust will not be a problem in the future." Muscle Car Review Magazine

Interesting Facts you should know about steel and prepping it before you coat it with POR-15 Rust Preventive Coating:
In every car manufacturing facility, steel in different parts of the car body often comes from different steel mills and different production lots, and the surface texture varies with the condition of the steel mill rolls which cold roll the steel to its final thickness.
Also, surface cleanliness varies with the mills cleaning procedures, especially the procedures used to control carbon smut is actually baked onto the steel during the high temperature annealing process which follows rolling. This carbon smut is impossible to remove except by mechanical abrasion.
Rust varies with the care taken in handling (1) at the steel mill, (2) during transportation and storage, and (3) during fabrication. Steel stored for a long time with rust inhibiting oil will react to form an incomplete oxide known as oil stain. The result of all this is that ordinary steel varies widely in the manner in which it accepts coatings.
Although some commercial steel provides an excellent surface for coatings, you are just as likely to find steel which gives poor adhesion and poor rust resistance, even with good coatings. Often the same mill will produce both very good and very poor surface quality, depending upon a number of uncontrolled factors.
Nearly all the above problems can be overcome by using POR-15 Metal Prep before you coat your steel. POR-15 Metal Prep is an inexpensive insurance policy that guarantees perfect adhesion of POR-15® Rust Preventive Coating to any metallic surface every time. Whether you paint your car or your fence or your outdoor furniture, the problems are always the same, because you don't know anything about the steel you're painting or what mill it came from, and you can't learn anything by just looking at it even if you have perfect vision!

Worked better than I thought

If you do the correct steps and in order the Metal Prep will adhere to any and all bare metal and if you let it cure for long enough the metal will look completely different. Make sure you use the degreaser beforehand.

Great product

I pulled the box off my Truck and cleaned it up good with a wire wheel. After rinsing it off I used the metal prep and then the POR 15.
The precess was pretty straight forward, It looks very good, I used a brush but it came out so good it looks like its sprayed on. Time will tell how it work to prevent rust.
