Rated 5 out of 5 by from This stuff is amazing! I've been using POR15 products for years both for personal projects and commercial. Metal Prep does exactly what it claims to do and does it well. Really takes the "work" out of a usually messy and labor intensive job. I've painted the treated metal within hours and the POR15 paint never fails. I have parts right now that I've treated that have been sitting for weeks and have NOT started rusting yet!

Rated 2 out of 5 by from did not like I used this product before applying por 15 and after I applied the por 15 it peeled and they told me that my prep couldn't have been right. Only i followed all of there videos and instructions so the only thing it could have been was the prep and ready did not etch the metal properly.

After my parts dry do I wipe off the chalky dust or just paint over it?

Asked by: Beckell
You will want to wipe this product off before it gets a chance to air dry on the part. When it air drys it leaves this chalky dust.

Can you use POR-15 metal prep prior to painting with Eastwood chasis black? Will it promote adhesion? 

Asked by: vvillarreal
This will not be necessary. Just thoroughly prep the surface and use the correct primer.

Provides the best adhesion for POR-15® on any metal surface

In stock

Only $34.99


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. Our simple process 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 will allow better adhesion of POR-15® Rust Preventive Coating or any other coating. POR-15® Metal Prep is not caustic, corrosive, toxic or flammable.

POR-15® Metal Prep Features:

Interesting Facts you should know about steel and prepping it before you coat it with POR-15: 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 dont know anything about the steel youre painting or what mill it came from, and you cant learn anything by just looking at it even if you have perfect vision!

Formally called Prep & Ready.
