## Description

Surface Cleaner, Metal Prep, 1 gal Jug, Each

Review: Hey gearheads!! I am quick to complain about products that do not live up to claims, but in this case I used a product which exceeded my expectations by far: Por-15. Our Saab is mostly rust free except for the frame rails in the front clip, and the rear crossmember (the crossmember is replaceable... /if/ I want to do a full rear suspension rebuild). Last winter before I put the Saab back on the road (a part was on backorder) I found the torque box joints in the front had thick flaking surface rust but now just seven months later the whole front frame is rusting. most "rust converter" paints are frauds and do not work. Por-15 is a multi-step system where you clean the metal with degreaser (I skipped that step as the frame only had a couple of tiny greasy spots on it), scrape off any flaking paint and loose rust, then you apply a metal prep solution that both etches and thinly plates any bare metal and converts rust into a different iron oxide forming a patina, and then you apply the rust preventer to stop the rusting process. Well I did the etching step today, agitating it with a steel brush, washed it and blew off the excess water with a leaf blower, then just went out to check it after it had time to dry. I was amazed; everywhere I had agitated it with the steel brush, the rust had either been removed down to bare metal, and where the rust was slightly deeper it was converted to a black oxide (a patina), and the bare metal sections had a very thin but visible zinc coating. This stuff actually works. and once the rust was removed I found the frame is perfectly fine. Because it has spread though I am taking the front end off to treat the sections covered by the bumper and spoiler panels then I will get a paint sprayer and paint it. if you're restoring a bike or car where rust is in the early enough stages that the metal is still solid, try Por 15. if you follow the steps like I did that are provided in reviews by people who have had good luck with it, the results will blow you away. Not only will I be able to get another winter or two out of the Saab but it will probably last a long time for whomever I give it to. That is assuming of course the frame isn't also rusting from the inside out but I have an idea on how to address that with a pressure washer, Por 15, and fluid film. for the rust preventer I chose silver because it provides more pinhole hole filling capability but fortunately that was unnecessary because I caught the rust early enough. Follow directions and you will be pleased. Be sure to agitate it and reapply the metal prep many times, keeping the parts you are treating completely soaked. Attached photo is of the front subframe assembly/engine cradle with metal prep only, no Por15 preventer coating yet. The patina is black when dry, and brown with a slight reddish hue when wetted with water. I did not take before photos but if the rear crossmember is bad (I haven't checked yet) I will take before and after shots when I get to it. I will be applying silver POR-15 followed by black POR-15.
Review: Used it works great. great quality

## Features

- ✅ POR-15 METAL PREP - Is easy to use and effective. It's formulated to gently etch metal, to create an ideal anchor pattern for coatings, while simultaneously leaving a zinc phosphate coating to insure chemical bonding of paint and steel metal.
- ✅ PREPARATION IS KEY - After thoroughly degreasing your work piece, apply 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. Metal Prep is Essential to create superior edge corrosion, undercutting resistance & improves welding conductivity
- ✅ APPLICATION - Remove loose or flaking rust, paint scale, etc. Surface to be treated should be free of grease, oil, and other foreign substances. Use of POR-15 Cleaner Degreaser is recommended. POR-15 Metal Prep works faster at temperatures above 70°F. Apply with brush, roller, spray, or dip rusted metal directly into solution.
- ✅ SAFE & EFFECTIVE - Our water-based formula is non-toxic, non-corrosive is safe to use, and won’t leave behind harmful residues.

I’ve been using this product for years. It cleans and removes rust from the metal before refinishing. I’ve never tried it on heavily rusted metal parts but mostly on lightly rusted metal parts. Eastwood had other rust removers that come in gallon sizes where you can immerse the parts and leave it in there until all the rust is gone. This container size is mostly to use on small parts or brushing/spraying it on the parts. Works very well though.
