Painting with Rustoleum
Yeah, I thought that would get everybody's attention. I frequent an old car forum where there was recently a discussion about painting with Rustoleum. I posted that if it were me, I wouldn't do it. From everything I've heard, the paint will not hold up, either structurally or cosmetically. The responses I got were interesting. A few of the guys claim they have done projects with Rustoleum mixed with reducer and hardener and sprayed on with a gun. They claim the paint is tough and long lasting and looks "good," or what they consider to be good, anyway. One guy claims he got the idea from a high-end resto shop in Atlanta. They do admit that it will fade if in direct sunlight for a long time, so the car should be stored indoors.
I don't know. It's a bit of a surprise to me. I'm using PPG products on my car and have come to this forum for all my information. I'm curious to know what you guys think of the Rustoleum thing. Not that I'm going to try it.
It's amazing the different opinions you get. I guess these guys' definition of "nice" has to be factored in. I would like to see a car that's been painted that way five years down the road. I wonder how it really holds up. I'm not doing it with mine. But you should hear them swear by it.
i do not know about rustolieum, but i painted a truck with modified acrylic enamel a few years ago. that was a mistake it did not hold up at all. the people who sell it will tell you that it does not last.
As far as I am concerned it is a Bunch of Boloney for anyone except those on hard times that would have no money No spray gun and a Junker type car.
it is NOT a viable paint method for any nice car..and it has only came up because Hotrod did a project like that. It will take More sandpaper to sand it flat between coats than you would spend on a Decent spray gun.
Because someone seen it in Hotrod...now it has become the REAL way to paint a car....Out of Nowhere we paint cars with a Brush in place of a Spray gun. Hotrod did that project too get more magazine sales. the only people I know who make ANYTHING of it are NON painters..soon becoming Experts
Great fence paint
I don't know about a car but u can paint over a rusty fence with this stuff and it will not rust back. Trailers and such its great on. I would like to try this japan drier. Sounds like cool stuff. POR15 has an excellorater kinda like that and buddy it works fast.
I've considered Rustoleum for my old Volvo. The car will never be worth more than 3K no matter how much I fix it up . Even though it's rare, there is is not much demand for them in the US. I also seem to have bad luck with people talking on cell phones ramming me in the trunk at stop lights. My last three cars were totalled this way through no fault of my own. I've decided that if I can just keep them from rusting and look halfway decent it should be good enough till the next ramming.
I've never painted a car before. I've painted lots of machinery with alkyd Enamel with good results, however, this stuff sits inside. The Rustoleum on my lathe and milling machine holds up real well to oils and cutting fluid. It seems that UV is what takes a toll on Enamels. I've head that White holds out the best and Red fades the worst. It makes sense since White is mostly inorganic Titanium Dioxide which is not affected by UV. Most new colors are organic pigments that need to be clearcoated to resist fading. The old single stage colored pigments were Lead, Cadmium, or Chromium based and were lightfast but toxic and are no longer used. I'll use the White if I go the Rustoleum route.
I'm going to be painting may car in the driveway, so a low buck paint job should fit well. I've also considered Acrylic Lacquer. It would be faster and easier than Enamel, but would it hold up any better? The only time I've dealt with Lacquer is when I stripped down an old milling machine and an old clawfoot bathtub, both had about 5 coats of enamel over their original lacquer. The paint stripper pulled the Enamel off in sheets but hardly touched the lacquer. I had to scrub and scrape it off with lacquer thinner. So it seems to adhere tenaciously to metal.
I painted my inside floor pans with rustoleum gray. They're going to get covered with some sort of sound deadening, carpet and padding anyway.
I brush and rolled it.
I would never do the body with it though

If I decide to go with Lacquer on my current project, I'm still going to use Rusto under the hood, on the floorpans, and underneath to keep costs down. Their satin black looks good on an engine bay.
I used Rustoleum on a car that had rusted out floorpan a couple of years ago. I welded in patches and wirebrushed the welds and used rusty metal primer followed by a black topcoat and it is still holding up underneath with no rust coming back. Their primers have corrosion inhibiting pigments in them so even if the film is scratched, some of the inhibitor dissolves and acts as a barrier to keep the corrosion at bay.
Rustoleum's true industral primers, which are only available at industrial supply houses, have a higher percentage corrosion inhibitor pigments and are thus a little more expensive. There's probably not much difference between their topcoats from the industrial line to the consumer line from what I can gather from the MSDSs.
In looking at automotive primers data sheets it seems that only the high end stuff from PPG, Dupont, etc. contain these same corrosion inhibitors. Strontium Zinc Phosphosilicate and Basic Zinc Molybdate seem to be the most popular ones these days. Zinc Phosphate which is used in some mid priced auto primers supposedly does not work as well. Red Lead and Zinc Chromate used to be the gold standards of inhibitors, but Lead is now gone completely, and Chromate is being phased out. The original Rustoleum Red Rusty Metal Primer had Red Lead.
I could not find any Lacquer primers with corrosion inhibitors. I don't know if this is because of the demise of Lacquer and thus no demand for high end primer, or if the Lacquer seals well enough to keep out moisture...It's most likely the former. So if I go with Lacquer, I'll probably use Epoxy Primer over the repair areas.
I painted a frame w/ Rustoleum 4 or 5 years ago, w/ a brush. Looked OK for a frame, I guess, but hasn't held up very well (maybe insufficient prep?). If I were doing it over, I'd use Zero Rust.
Rolling on Rustoleum for an exterior finish sounds like one heck of a lot of work for what you end up w/. Read the Hot Rod article-yeah, the materials were pretty cheap and it looks nice (for a while, anyway) not great. But they sanded it a whole bunch of times and it took many days. If your time is worth nothing, maybe it's an interesting science experiment, but I'd MUCH rather get a low buck gun and bargain line urethane.
I can see doing it to floor pans. In fact, yesterday I was pulling the rear carpet section out of my big Merc to clean up. The tar padding fell to pieces but there were just little spots of surface rust. After degreasing the section I put a little Ospho on the rust for overnight while I pondered the painting. Then it hit me. Why not use my industrial based Kelly Moore paints I have down on the ship. Red primer followed by seafoam green topcoat then the underlayment and carpet. The stuff stands up to tougher environments with water and salt air so why not the floor pan. Even better the floor pan is seafoam green right now. Body wise never as it will fade due to UV.
I also tried the hammered metal paint for rusted metal to see what it will do.
It seemed to grab the rust just like Zero-Rust. I'm not sure of the long time durability or adhesion of it though, so that's why I used it on the rear end. It'll get a lot of road abuse, and it's easy to remove if I have to re-blast it, and repaint it.
BTW... that's ZR under the car.
B M Impervo
I have used Benny Moores Impervo, High gloss Oil on parts for my tractor using a Sada gun with excellent results. They make all the Saftey colors pre-mixed, If you plan on a few heavy coats, use the Jap dryer. Make sure it it is the exterior product. Really stands up in the field as well as non fading outdoors.. sprays like a dream. Also use it on all my metal exterior doors
about 30 bucks a gallon.
