## Description

The Por-15 3-Step Stop Rust System Is Designed To Stop Rust On Metal Surfaces And Ensures The Best Results When Applying Por-15 Rust Preventive Coating. The Clear-Cut Process Allows For The Proper Cleaning, Prepping, And Coating Of Metal To Create A Non-Porous Surface That Seals And Protects Metal From Water, Chemicals, And Salt, And Other Corrosive Contaminants. The Por-15 Stop Rust Kit Covers A 6 Square Foot Area With Two Coats Making It Ideal For Small Projects Like Sub Frames, Axle Replacements, Control Arms, Brake Shields, Etc. This Kit Contains Por-15 Cleaner Degreaser, Por-15 Metal Prep, Por-15 Rust Preventive Coating, Paint Brushes, Latex Gloves, And Detailed Instructions. Basic Directions: Gloves, Eye Protection, And A Properly Fitted Respirator Should Be Worn Whenever Handling These Products. Step 1. Remove Loose Rust With A Wire Brush. Apply Por-15 Cleaner Degreaser To The Surface, Keep Wet 10-15 Minutes Then Rinse Thoroughly With Water And Allow The Surface To Dry. For Areas With Noticeable Build Up Use A Stiff Brush To Break Up Material And Continue To Keep Wet With Por-15 Cleaner Degreaser. It Is Important Not To Allow The Product To Dry On The Surface Prior To Rinsing With Water. Por-15 Cleaner Degreaser Is A Heavy Duty Water Soluble Cleaner That May Be Used Over Metal, Wood, Fiberglass, Vinyl And Concrete. Step 2. Apply Por-15 Metal Prep To The Bare Metal Surface, Keep Wet 10-15 Minutes Then Rinse Thoroughly With Water And Allow The Surface To Dry. It Is Important Not To Allow Por-15 Metal Prep To Dry On The Surface Prior To Rinsing With Water. Once Dry The Surface May Show A Flash Rust Or White Powdery Residue This Is Perfectly Normal. Por-15 Metal Prep Provides The Best Surface Profile And Greatly Improves Paint Adhesion To Any Type Of Metal Surface. Step 3. Apply Two Thin Covering Coats Of Por-15 Rust Preventive Coating. Apply The First Coat To The Properly Prepared Substrate With The Supplied Brush. Apply The Second Coat When The First Coat Is Almost Dry, Slightly Tacky To The Touch. If Por-15 Rust Preventive Coating Is Applied Too Heavy, Brush Marks May Result In The Finish. Do Not Apply This Product If The Humidity Is Above 70%. If The Humidity Is Too High Por-15 Rust Preventive Coating Will Surface Dry Too Quickly Which May Result In Small Bubbles In The Finish. Por-15 Rust Preventive Coating Requires A Top Coat Only If Exposed To Direct Sunlight. For Top Coating Use Por-15 Top Coat Or Our Two Part Topcoat Por-15 2K Urethane.

## Questions & Answers

**Q: what color of por 15 rust preventative coating comes in the kit?**
A: Gloss Black.

**Q: I tried using cyran wrap/wax paper to close the can but the lid keeps poping open. How did you reclose the can in a way that you can open it again?**
A: I put both layers of a plastic sandwich bag over the can and then tap the lid shut.  Use a hammer if you have to. That will keep it fresh for a week or 2.

**Q: Can this be applied in 40 degree temperature?**
A: No, POR-15 is best applied at temperatures between 50 and 85F.

**Q: Can this be used to repair body car rust? My car is silver- will it be difficult to paint over the black?**
A: I sanded down a small rust hole on my truck fender. I then took a small wad of steel wool in the hole then covered it and about 2” surrounding it with two coats of Por-15. Then sanded, primed and painted the black Por-15 with Sunburst Orange pearl coat. It looks great and that was a year ago!
