Magic Rust spray. Start to finish. explained in detail. everything you need to know

[@alanmcrae8594]

Thank you for this video. I was researching rust converters to learn what the actual active ingredients are, so I wouldn't end up paying for an assortment of inert ingredients that seem to be present to justify a ridiculously high retail price to consumers. At first it seemed to good to think that just some phosphoric acid & glycerin gel would be sufficient, but then I saw some honest diy presentations like yours that confirmed the simple chemistry involved & the low price for raw ingredients. This is the internet at its best! DiY'ers sharing their experience and saving the rest of us from high prices for simple chemical mixtures. I really appreciate your presentation & suggestions.

[@justahandchannel]

I am pleased to be of assistance. I was once in the same position, searching for the solution, and I hope to save others valuable time and resources.

I can't thank you enough for sharing this with us. As a 74 year old man on social security I did not know how I could afford to get rid of the rust that had been running rampant on my 1979 jeep under carriage since moving to Michigan 3 years ago. The commercial products they market is way out of my price range . I found a gallon of Klean Strip concrete and metal prep at home depot for less than $20.00 and a hand sanitizer with ethyl alcohol for $6.00 at the dollar store. This worked so well I am surprised. A big percentage of vehicles here are being consumed by rust , keeping it from happening to my jeep was a concern. THANK YOU!!!

[@justahandchannel]

You're very welcome and thank you for posting your comment. It's nice to know that I could give you an answer to something that you might not otherwise have been able to do. Stories like this make it all worthwhile for me

[@michaelschlup-c5o]

after spraying and rinsing off the phosphoric acid.... let it dry and buy a qt of Penetrol and get a spray bottle and soak it down twice ... let first coat dry and then soak it down again.. good to go for a long time ...

Hi from Ontario .Once you get rust of your frame and painted and dry spray entire chassis frame rockers doors and all inner panels brake lines with oil missing nothing . You have to do the oiling yearly or more . Good luck been doing this for years on my old cars and trucks .I even pull up my carpets and coat floor pan and drill 1/2 inch holes in areas that i cant access. Make sure to spray inside of the frame as they rust from inside badly just coat it

[@vtxdaryl]

Will it take rust off sidewalks and driveways and will it kill any grass or plants it gets sprayed on?

[@joarandrehansen]

I believe the gel-substance in the hand sanitizer is made by adding around 1-2 % Glycerol/Glycerin. As a nurse, I use a lot of hand sanitizer, and the ones with glycerol really makes the rubbing alcohol stick to your hands, so no wonder it make the phosphoric acid stick to the metal.. Great job..!!

[@drizler]

Here is a bit of advice to the first timers here not overly familiar with the rust monster. Don’t expect this to effectively deal with flaky rust. You know that kind of stuff I mean it has a physical raised appearance and is loose. You’ve got a knock that stuff off, preferably using high speed grinder and wire wheel for time-saving. Once you get all that flake off, then you’re all set for the treatment. Another method that I love to get rid of flake is using a blunt to point tip on an pneumatic air chisel. You don’t cut with it but let it bounce on that flake. I guarantee it will take it off far better than the Ingersoll, rand air chisel that I don’t use anymore. Besides, a cheap air chisel works just as well. as a good one for this 👍🏻

[@markconley9279]

Are you referring to a needle scaler?

[@JohnSmith-uk1vb]

@@markconley9279 I'm familiar with a needle gun. Our fab shop had one, but if you have a air chisel and use a rounded or extremely dull chisel bit, it works as a poor man's needle gun.

[@StormyJoe1999]

i use a hammer.scraper and wire brush. works fine

[@davidclemens1578]

​​@@StormyJoe1999I have a 92 F-250 that had heavy flaking rust on it and that would not do it unless I used the needle scaler, then I used the wire brush on a drill. On the large areas it was a wire cup brush and on the smaller areas I used a end wire brush on a drill bit extension attached to my small air grinder. After that I washed it down with Simple Green cleaner and water then I rinsed it with mineral spirits and painted it with Rust-Oleum implement primer and paint. After a short time it actually started bleeding through from the heavy paint coat but what I plan to do is use fluid film over the whole surface. It is lanolin based, which will actually replace any moisture in the rust and any paint that had pinholes or areas the paint did not cover. By the way fluid film or a product by blaster will last one to two years depending on the driving conditions and where you live. Those that use it consistently have had almost no rust.

Same here. In the 70s I worked in the waste water monitoring industry and we used a product called Fozz. I just did a search and it is still available. Main ingredient is phosphoric acid. Great stuff.

[@jeffreystroman2811]

Is the acid used to lower the Ph of pools the same? I used that to sharpen a bunch of hand files overnight or maybe 2 to 3 days tops. I do dip the files in water and baking soda to neutralize so I thought maybe it's different acid.

[@justahandchannel]

Pool places generally carry phosphoric acid. Yes. No need to neutralize

[@voidisyinyangvoidisyinyang885]

​@@justahandchannel I've done the same thing - using the Kleanstrip concrete and metal prep from HD - very cheap compared to the "brand" car rust converters! I had two local mechanics refuse my chassis - three years ago or 50K miles ago. I did get a chassis repair kit welded on by a farm mechanic business - otherwise just scraping rust off with metal wheel brush, phosphoric acid and epoxy paint and then cosmoline paraffin wax. I used a camera to see inside the chassis - spray phosphoric acid to treat in there. The chassis seems much improved. Still working on it - since I didn't get epoxy paint on till this year. The ONLY epoxy spray paint sold at our home improvement store is for metal appliances - kind of like the phosphoric acid work around. hahaha. Epoxy paint is so much better than enamel paint - to keep the salt water from penetrating. thanks

Just an update from my end. It's not quite spring yet, but we have nice days here and there. Today is okay, very sunny and dry. So, I went out with my mixture of this stuff (I used Krud Kutter, mixed with hand sanitizer) and sprayed some on a few spots of my utility trailer and the rear frame rails of my Jeep Wrangler. I don't have the primer or any paint that I'd use afterward, so this is a test. It's doing what you've shown. On my Jeep where I sprayed, it has that white milky look after about an hour. The trailer looks more like the spots are very silver (bare metal) and no white haze.

[@justahandchannel]

The white haze is normal. It's just from the chemical Drying on the metal. You could try a blow gun next time and blow it off after spraying

[@turn-n-burn1421]

@@justahandchannel I was aware of that haze, because you'd mentioned it in at least one of the videos. I was just kinda confirming that it was doing that. It didn't matter that day anyway. We're in that weather pattern coming into spring, where it bounces back and forth. It'd been sunny and dry for a couple of days and I just wanted to experiment. I still have to get the primer before I actually do it properly. I sprayed it on a few things outside besides my Jeep chassis; also a utility trailer and something I've forgotten.

​​@@justahandchanneltell me about it. My buddy and I spent the last four years restoring his 67 charger. He did the stripping on the body down to the bare metal and took her to a body and paint man, that had actually had cars at SEMA, finish the body and paint the outside of the car. After that he got it back and we went to put new carpet in it and the floorboards were bad as a result of an open rear window in a Colorado field. So I welded in new floorboards and we completely rewired it from front to back and had to reinstall all the lights and other accessories. He took the seats to someone that did an awesome job recovering. After 2 years of completing the interior and going online hunting for all the missing trim pieces and replacement window and interior trim parts and accessories. He finally got the car on the road 2 years ago at the end of the summer and won four trophies. Unfortunately this past year his engine was starting to act up as a result of sitting for the years prior to restoration. He thought it was carburetion and invested it into a fuel injection system which he had intended anyway. He just got his engine back and in a couple months, will be installing it to be ready for next summer. Hopefully he is done with the major work but even with all of our free labor the car almost put him in the poor house. He has had this car since he was just out of high school and he is now 60. He always dreamed of getting this car back on the road and hopefully this year, he will be done with the majority of the restoration. The car is beautiful and definitely a labor of love.

Rather than a garden sprayer I would recommend some kind of spray gun that runs on air or even one of those pump pressure sprayers. I think you'll dilute it too much with the garden sprayer. I wouldn't imagine it is going to hurt anything under the car. However it can change the color

Just an update. Of course it's smack in the middle of winter up here in the Midwest, but I finally gathered everything to do this when all this garbage weather is a memory. I wound up getting a gallon of Krud Kutter that's phosphoric acid. I'd already bought a spray bottle and some hand sanitizer. I was going to get Klean Strip, but Krud Kutter is less expensive. My Jeep frame, the body isn't so bad, has significant rust. Question: Is there a way to make this stuff into a gel like substance so it will stick to the underside of metal for a bit longer to do its job?

[@justahandchannel]

There's no need to make it stick.. Then you would just end up with a mess to clean up if you're planning to paint afterward. Just spray it on liberally And if you don't see good results after an hour, then spray it again.

@justahandchannel the throttle shaft was seized very tight, after soaking for a few days I was able to barely get it to move, only just a fraction at first though. I'd let it soak again hoping once it broke loose the transmission fluid would be able to soak in better. I didn't want to bend the shaft so I was careful not to torque it too much and force it. It's moving freely now. These Weber carbs have sealed bearings on either end of the shaft, the problem wasn't with the bearings but the center of the shaft where it passes through the base of the carb.

Can You Paint Over Self Etching Primer? Self Etching primer can in fact be painted over but you need to closely follow the manufacturers application and top coat guide. As a rule of thumb Self Etching Primers need another coat of primer over them to fully seal everything up long term. We suggest using a Urethane Primer over the self etching primer as a barrier between the self etching primer (Do not use Epoxy over Self Etch). Urethane primer can be top coated with most coatings so you will immediately eliminate any worries of adhesion issues with your top coat.

[@justahandchannel]

Your information about self etch primer is correct, but I'm not sure where this topic started as I never recommended using self etch primer. It's a product that's unnecessary in proper restoration.

Thanks @justahandchannel for researching an inexpensive rust converter 👍😃 Not every Tractor Supply has it, but I was able to find milkstone remover $22 and used it full strength along with some cheap $2 hand sanitizer to rust convert my truck's trailer hitch receiver, some bolts and garden tools. But I do have questions about a white residue or precipitate I was seeing. For the trailer hitch receiver, I wire brushed inside/outside. Then sprayed and let it marinate and dry overnight. It worked well and turned the rusty metal blackish. But the next day, I also noticed inside the hitch receiver, where most of the spray landed on the flat interior surface, patches of hard white preciptate/residue leftover. The white residue was pretty tough, but it could be scraped off with one's finger nail or with a wire brush along with a little more spray and a rag to remove any excess. I think this white residue must be removed before any painting can be done? Not sure. Anyone know if the white residue left behind is dried phosphoric acid or is it a precipitate from the phosphoric acid / rusty metal reaction? I noticed that once the white residue was removed, underneath it the hitch receiver had been etched right down to bare shiny metal. So I wonder if I used/sprayed too much? I was also rinsing with a garden hose, wire brushing and respraying a little. Too much water? Anyone know what this white residue is and maybe how to best avoid it? I also treated some Subaru Outback headlight assembly retaining bolts, 14 of them. "Headlamp Assembly Bolt - Subaru (57737GA290)" as a few were a little rusty, but most not too bad. These are steel and appear to have some kind of black (paint? oxide?) coating on them (I assume it's paint, since they are steel it cannot be anodized, but maybe it is some other coating?). Anyway, the spray "full strength" removed that black coating down to bare/gray metal which I did not expect. In this case they came out gray with white residue spots. I ended up brass brushing, respraying and wiping them down to remove a white residue. I have since repainted them with black appliance enamel and they look great. Maybe I should have diluted down the phosphoric acid in this case. So for some purposes one might want to test this mixture beforehand. I'm also going to trying it on the Subaru's front end frame after I use a needle gun to remove any flakey rust (mostly near the frame welds). The factory frame paint looks to be more robust (epoxy?). I will repaint it alll with TS oil based Farm Implement paint with their cyanoacrylate hardener, as this has lasted on another vehicle I did prevously. Finally, the spray did a great job on a crusty / rusty steel 8"x8" hand tamper... I used a needle gun to clean it up first. The tamper was previously leaving rust stains on the concrete floor, but no more, now the rust on it is all converted and has a protective black coating. Garden shovels and tools are next...

[@justahandchannel]

The white residue is from moisture. It doesn't affect paint other than it won't be a smooth surface. If you spray too much on, you can just wipe it lightly after spraying and that will keep it smooth. Wire brush will also remove the residue. Hope this helps!!
