- Rust is the enemy of a classic truck meant to be driven. Whether it’s your original floorpan and framerails or all-new sheetmetal, if you leave it alone long enough the elements are bound to do damage. Before we go much further, no, a couple coats of black rattle can just ain’t gonna cut it! What you really need is to clean and prep the metal the right way and then seal it with a product that will actually last. From our experience, POR-15 has a robust product line dedicated to doing just that.
All this talk about preventing and protecting came about when we started planning the build of our ’64 Chevy C10. Step one of the build is going to be a complete front subframe install from our friends over at Scott’s Hotrods ’N Customs. While we could pull a Roadkill move and bolt the fancy new front suspension to our grimy old framerails, we’d rather do it the right way. That means cleaning, prepping, and sealing things up beforehand. It’s a process that, depending on your level of filth, could take just a few hours or part of a weekend, but it’s a process that is completely worth it in the long run.
In this article, we’re going to focus on four products from POR-15: Cleaner Degreaser, Metal Prep, Rust Preventative, and Top Coat. Using our C10 as an exemplar (and a couple other In The Garage Media project vehicles), we’ll show you when, where, and how to use each one.
Applying POR-15 Metal Prep to surface rust
The Magic of POR-15 Metal Prep
We noticed POR-15 Metal Prep was advertised to remove surface rust. It seemed too good to be true but we decided to try it out anyway. Scudellari’s Model A body had been sitting inside the ITGM Tech Center for a few months awaiting a complete build (look for it in a future issue of our sister publication Modern Rodding). Even in Southern California, rust finds its way. With the same methodology as he used on the frame, Scudellari sprayed a rusted part of the body and let it soak. After just minutes he was able to wipe away the rust with a clean rag. If you want proof that this isn’t just a cheeky Photoshop job, watch the video. We were impressed, to say the least.

POR-15 Cleaner Degreaser
This waterbased product is designed to clean everything from minor dirt to serious grime left behind by oil, grease, mildew, and even wax. The fact that it’s waterbased means it can be diluted as little or as much as each situation calls for. It also has an added benefit of leaving no residue behind, and it’s almost completely odorless. Plus, it isn’t flammable so no need to worry about grinding or welding on a metal surface that was just cleaned. POR-15 Cleaner Degreaser comes in a gallon bottle, or pre-diluted in a spray bottle for ease of use.
POR-15 Metal Prep
Even when a surface is free of dirt and grease a final step should be done before a coating can be applied-that’s where POR-15 Metal Prep comes in. It is designed to etch the metal surface for optimal adhesion while also leaving behind a zinc phosphate coating to further help bond paint to metal. Like POR-15 Cleaner Degreaser, Metal Prep is waterbased, non-toxic, and non-corrosive. It is also effective at removing paint scale, loose or flaking rust, and even light surface rust.
POR-15 Rust Preventative
When it comes to stopping rust, POR-15 Rust Preventative is the best we’ve come across. Once the metal surface has been properly prepped using Cleaner Degreaser and Metal Prep, this permanent coating can be brushed on. It forms a barrier against everything from water to salt to chemicals and wear and tear from everyday use. It cures into a “hammer tough” coating that POR-15 claims is virtually indestructible. Beyond just protecting metal surfaces from developing rust, POR-15 Rust Preventative can even be applied directly on rusted surfaces to stop the spread.
POR-15 Top Coat
When a durable, UV-resistant coating is required, POR-15 Top Coat is a great option. Available in a convenient aerosol can or traditional paint can, Top Coat is a direct-to-metal paint that does not require primer or coating. Its UV resistance and rust-preventive qualities are designed to provide a permanent barrier to corrosion and impressive long-term color retention. It can also be used on top of POR-15 Rust Preventative as an additional layer of protection with many colors available.
Por 15 good stuff I’d add topcoat to the painted surface. Seems to flake after a while and the topcoat helps prevent it
I put it on my Big Red rack after sandblasting it. It gets cover 90% of the way and time but its actually held up very well after 7 years without topcoat. I would suggest topcoat though. This product does chip..it's kind of its weak side. Foam brushes so u can toss them...cleaning this product sucks. Buy 8 oz mason jars to pour into because once you open the lid it will weld shut on you and if you have air left in the can it dries it solid.
We agree top coat is the way to go
PRO15 is good stuff, thats for sure. Did my whole 76 C20 frame, body off. I found a 4.5in paint strip wheel worked really well for knocking the rust off. You know the silicon carbide scotch brite wheels. Anyway, did the three step as you show, still on there. One tip I would give is invest in one layer of "top coat" as the PRO15 out of the tin that you and I used is not UV stable, but the top coat is. Thats if you want to keep that shine on your frame. Thanks for the video. A great addition to the Classic Truck Performance Magazine!!
Thank you for the good information.
As I mentioned, and to add to your post, that additional uv top coat has to be applied while the baaecoat is tacky because it won't adhere to the base unless it is still soft. Weird but true.
Por 15 on the frame wasn't really done properly, if you read the instructions, it's NOT a finished product, you're supposed to top coat WHILE IT'S STILL WET (slightly tacky) to give it protection from UV. That's the part that makes this product hard to use because it dries past that point quickly in warm weather. They make a special product to apply over it if you don't get it top coated immediately to promote adhesion. The DTM version is much easier to use and doesn't require top coating because it is a finished coat.
I want to buy your 64 truck, when you finish it.
From independent reviewers here on RUclips, POR-15 is crap unless you use the top coat. Even then, it does not last long without rusting. I fell for this advertising ploy, but no longer.
