I keep POR15 almost indefinitely. When I open a can, stir well. Pour off what you need. Pour the remainder in a clean mason jar. The reason for the jar is you can easily clean the lip. Cap air tight. Never return used POR15 to the jar and never dip brush in the jar. Works very well for me. Great video.

[@gorr4]

Very nice, I wish somebody had a video for spraying the stuff about 10 years ago! & yes do not get any on your self, think it took like 6 weeks to get that stuff off my hands! ;-) Side note, it's not like nomal paint! So it's very important to not get it in your eyes.. after talking to the rep about spraying it, I bought a full face respirator just for woking with the por-15. Anyways I cleaned up the engine bay on my accountants 1954 Chevy 3100 A wile back. As thing do, It snowballed into a much bigger job, that included stripping and painting the front half of the frame. (he wanted to do the back half later to save $) I used those skinny "behind the toilet" paint rollers on most of the frame with the POR 15. Worked great, I was very impressed at how it leveled out! After some Hammer & Dolly work, priming and a lot of sanding.. I sprayed the core support, upper radiator shroud & inner fenders with POR-15 Top Coat. Now beinng in the Socal desert , my first time spraying a high solid & in August to boot.. the paint was drying before it hit the metal! But after scrambling to clean the paint off before it set & increasing my solvent ratio to like15% I was able to get it to flow nice. and I 100% recommend spraying it, because it came out way better than the rep said it would! 🙂 I'm no content provider but the 54 is on my channel if any one wants to check it out.. there's hardly anything there, so it should be ez to find lol

[@FastMonty]

Thanks for the story, and awesome testimonial! Yeah, just getting the vapor in your eyes stings like a MF'r. I probably would've been better off with Super Glue eye drops. Agreed a full face respirator/air supply is the way to go... which I have, and didn't use it. So, dumb. Anyway, thanks again for the awesome comment!

[@gorr4]

@@FastMonty yeah I was totally covered up and using My respirator even on my back rolling out the frame.. everything went perfect issue free, until I saw a little spot I missed and I hit it real quick with the roller not wearing my respirator and of course I got droplets in my eye..

I wanted to add a comment of caution here. Dry time accelerator is used here for a quick cure. 15 minutes vs an hour. My caution is that if you are covering metal with significant rust on it, I would want the longer cure time even with runs. The reason being that por-15 cures using moisture. It pulls it from the air but more importantly it also pulls it from the rust. I would think the longer dry time will allow the por-15 time to pull more moisture out of the rust leaving less chance for it to be sealed in and available for more rusting later.

[@FastMonty]

Good point... however, if the prep solution is used correctly (Phosphoric Acid) there shouldn't be any rust left. The Metal Prep neutralizes the rust and also leaves a zinc phosphate coating, a known rust preventative. The POR15 then seals all that up for further moisture barrier. From my experience, the humidity of the environment determines the cure time. I'm in San Diego... which is mostly dry. On a super dry day, it takes up to four hours to cure one coat... that's just to get "tacky". On a humid day, I've seen it tack up in 30 minutes. So, the environment, combined with your desired of spray "tack time", should determine the use of the Accelerator. Hope that helps. Thanks for the comment!

I'm about to redo my ole mans 50+ year old Snapon tool boxes. Someone turned me on to POR15. Your video convinced me. I was about to spent a lot of money on a bead blaster from Harbor Freight. (Something I'd rarely use). I'm also finding that you can paint over POR15, if you don't want black or gray.

[@FastMonty]

That's correct! If you're resurfacing the exterior, make sure you sand it perfectly flat. And yes, you can top coat POR15 within a certain time frame. Have fun!

[@phoenixmistertwo8815]

I just used this POR15 for the first time, and my dilemma began with a rusty fuel tank for an old Mr2. I first used Muriatic acid to de rust the tank and it worked well. Then after that long process, I began the task of sealing the inside so it wont rust again. I didn't want to do a rolling method with this expensive stuff, as I worried about puddling and bare spots and clogs, so, I devised a way to use a Previa atomizer and thinned it out with Acetone. Once I finished that, I realized that the top of my fuel tank where the ports are for the FP, sender unit and evaporators, were lacking contact with POR15. So I ended up using a flexible paint brush I could extend and shape, and just as well, my gloved fingers to brush on this stuff to those areas around each port. Well, while doing that, I noticed that some of this layer I painted and dried, came off like old box tape accidentally left on while painting. This was not tape though, it was a layer and strip of POR15 that came off just like tape, along with the stuff it stuck to, like surface rust that even that acid was unable to soak and get. That all said, this happened either because I diluted too much of the POR15 with Acetone, to get my atomizer sprayer to work properly, or, its just because there was some light and rough surface rust leftover at the top of the tank, and it came off with the rust it stuck onto. I would rather it be about leftover rust on the metal that didn't allow the paint sealer to dry on clean metal, but I worry just as well, that I messed up the chemistry of the sealer, by using nearly 1/3 of acetone to thin it out enough to work with this particular sprayer. I know I am beyond the 5 percent that the POR15 calls for, but still, should that just mean each layer I painted would just be light on the substance. I did layer it as much as possible, and areas I was able to directly spray seem pretty nice and thick, but, if this starts flaking off in my tank I am screwed.

[@FastMonty]

Thanks for sharing your story... yeah, changing the formula is not a good idea. (Including the use of Muriatic Acid, which is Hydrochloric) The acid you should use needs to be Phosphoric. That leaves a Zinc Phosphate coating on the steel, to prevent future decay. Anyway, if you're saying you coated the inside of your tank with POR15, I'd recommend buying a new tank. As, I don't know if POR15 is fuel proof. Sorry for the bad news, but that's how I see it. Let us know if I missed something here...

[@phoenixmistertwo8815]

@@FastMonty , the video was excellent and I thank you for it. The painting seems to be decent now, after another 12 hours of drying buy I bet I gave some bare or thin spots that could flake off. I read that it's repellent to gasoline but....I may not have read that from an actual Chemistry sheet from the product. Hmmm. Well, I better check that out to be sure as forums can sometime lead you astray. It did have quite the coat and it sells for reasons I saw online for motorcycle tanks, but I also hear that many won't speak about fuel tanks in cars since some states make that illegal along with handling muriatic Acid. I never played with that before but am happy with the results since this tank had alot of bad and rough rust...i did a 16 hour soak, 1:20 mixture with water, and it did get me to clean bare metal but I had 14 gallons to neutralize with baking powder after, and it took alot of baking powder. It was very strong as well, it burned when it hit my skin, and it gave me a nasty headache with its vapors, but, aside from all that, it went well. ;) This sealer, well, I made a big mess but I did get it sprayed in my tank eventually, and on my bare hands too after my gloves tore...The stuff is still on my hands as I write this, and it's a testament to its strength. I would do so much better if I had to do it all again, since I had to stumble through all this to learn the hard way about this process. I have to consider taking my tank to a professional, but, before that I'll at least try by soaking some gasoline in there for a day and night and see what happens. It's for a classic Mr2 Turbo, of year 1991, and a new tank is nit available. I can perhaps get a hold of a used one from the car clubs, but I'd have to clean that as well to ensure years of protection. I may 'roll' the last half of a quart I still have to ensure I have it at least topped with some of this unmixed polymer. This is what I wanted to avoid but, I think if I do it in small increments I may be able to get a good coating throughout the tank, and get past the partitions within the tank. First things first, I need to make sure this stuff is fuel repellent as many have said it is, and many defacto brochures and forums have stated.

Thanks, I like to see what is still around and new technology, updates ect! Two suggestions, first use a small thumb twist regulator on the spray gun base, for fine tuning airflow and pressure, second at your air supply down line runs, use a tee for actual supply and extend about 6 inches past the tee, as a additional water/partical trap, with or without a valve for drainage. If no valve clean periodically, with removing cap. House of Kolor, very good stuff, from decades ago experience!

Will the metal prep eat through existing paint? I'm curious as I am coating the undercarriage of a infinity G35. Not looking to strip everything down to bare metal... also there are some spots where the rubberized undercoating from factory has been scraped from car being low. Any recomendations for replacement (por15 rubberized coating any good?)

[@FastMonty]

Good questions... Metal Prep "eating through paint"? depends on the paint, I don't think it would remove it. You can paint over anything, but it will only last as long as the substrate can handle it. Haven't used the the rubberized coating yet... let us know!

[@robertthrem3382]

If you use the 3M disposable cup, it will come with a cap and it has a measuring on the side of the cup. And when you let it sit, take the gun off spray some 3M paint gun cleaner into your gun and hit the trigger a couple times. That is some powerful stuff.

[@FastMonty]

Ahhh, I have those cups too... I love how you can measure in the cup, but don't like how you can't spray upside down. That said, great tip on the 3M Cleaner. I haven't tried that yet. Thanks!

[@markjackson6829]

Very good gun technique! 2 recommendations, 1 with a top loading HVLP gun limit your time more when gun is not vertical, especially if gun cup is low, 2 use a box fan with an a/c type filter taped to it, for intake only on low this will help clear out your "paint booth" and keep particles out. Do not use fan as an exhaust, as paints mostly are flammable and box fans do not have explosion proof motors!

[@FastMonty]

Good stuff Mark... small parts don't necessarily need a vent. I probably could of utilized one. My gun can shoot upside down, which is why I love the DeKupps system. But, most other guns can not shoot more than a couple seconds upside down. Thanks again!

Hi! I really enjoyed your video. I just purchased my first POR-15 kit with the prep components. My plan is to use the kit for the floor wells and those trunk wells behind each rear tire. The problem is that all of these locations are ‘captive’ and I don’t know how I would wash off the prep components. Unfortunately or fortunately, my 1967 car doesn’t have any rust holes so I can’t rely on them to allow for water drainage. Any thoughts on this? Maybe a shop vac to evacuate flushing water.

[@FastMonty]

Thanks... I get it. I'd recommend using a wet sponge, like a sponge bath. It'll take longer to clean and treat but should be less messy for prep. Have fun!

I unfortunately don’t have a house and driveway to do the prep work so any work I do at my apartment parking lot has to be done fairly quick. Would cleaning rust off with wire wheel be enough for prep work. Don’t need it to be perfect just want to slow down rust.

[@FastMonty]

Hey Emmanuel... good question. Just knocking off the loose rust will not stop the oxidation process. After you knock off the crud, you have to degrease it, then coat it with the Prep Solution. That solution is basically Phosphoric Acid... when it reacts with the Iron Oxide (Rust) it'll convert it to Zinc Oxide, which stops the oxidation process, and acts as a rust inhibitor. Then, and only then, do you coat it with the POR15 paint. Yes, you can brush it on. Hope that helps.

One thing I will say, they have some pretty high HP machines.

Yeah, it does lay down nice, including spraying it... sounds like your friends need to stiffen up their chassis' ha, ha... :) That said, I don't have any issues with cracking, I also don't have 1200 hp, yet.

If the blackboxes material is so strong, why don’t they make the whole plane of the same material? Which is of course just a joke. But on a more serious note, if POR15 is so great, why don’t OEM painting their undercarriage parts with it to begin with?

Is it true there needs to be some rust present for POR to work properly?

Good question. No. Some people do a lousy job cleaning, and prepping, which is the most important. The Metal Prep step coats bare steel with Zinc, where if there was rust present, it will stop the corrosion, and also convert to zinc oxide. But, if there is any oil or grease present, it won't work. Hence the cleaing step. You have to be patient with cleaning and prep, before painting. Do all the steps properly, and it'll come out stellar! Have fun!
