RUST BULLETIndustrial - Metallic Gray - 1 Gallon - Low VOC - Rust Preventative Coating for Industrial, Marine, Home & Farm Projects, UV Resistant, Durable Finish

I've used rustbullet for years now. It's a great but quarky product. First thing is if you only need a pint, buy a pint. Or buy 2 pints but open just one. The second one will be good as long as it's not opened. I think the shelf life of unopened is a year.This sounds silly but the product is activated by being exposed to air/moisture.. the more space in the can, the more likely it will harden in the can. The company sells an arisol can to spray in the opened can before closing to extend the opened can shelf life.Now that's outta the way.. this is a great product. It's a rust encapsulate product. Dries hard as powdercoat and solvent resistant. The only way to remove it is. Paint stripper or sand blasting. It is a very nice sanding product, powders up nice, doesn't gum the paper.If you are encapsulating rust with this, you must coat both sides of the metal. If not the rust will grow again and bubble this product.If you get it on you, wipe it off with their solvent before it dries or it'll be there for days until it wears off.Application. All of the rustbullet products look better if sprayed. Especially the colors.If your treating heavy rust I'd recommend brushing it to get better penetration for first coat. After dry, sand out brush marks and any bubbles created by the product drying. Pooling of the product, heavy brush strokes,and runs will cause bubbles while drying, the product swells when pooled. Sometimes good if your trying to get the part sealed well. You will see what I mean.Second coat of this you can brush, but spraying is a better result. Just buy their reduced. I've used automotive urethane reducer in a bind. I don't recommend a second coat brushing until it's dry and sandable.. a second coat spraying, can be done in about an hour after there is no paint transfer if you touch it. Still sticky though.Read the instructions that are avail on their site or on the can. This product is not like many other paints out there.As an Autobody tech for 30 years, I can assure you that if you follow the instructions and my tips, you will be happy with the result.

I live on the coast, my boat trailer rusted, I had metal roofing that rusted, our water treatment sand filtration tanks (housed within our treatment build) had issues with exterior rust due to the exposed to chlorine. This is my number 1 paint for rust issues. If it needs to last, check it out.

Works like a champ, provides a tough and durable coating and absolutely stops rust in its tracks,

I am not 100% sure which Rust Bullet I used for this project but I have had similar results with Industrial, Automotive, and ProPlus. Three years ago (or perhaps four?) I cleaned up and painted a very rusty metal shelving unit that was in my basement next to the utility sink. I prepped the surface well and used Rust Bullet paint (probably 4-5 coats) and then topped it off with Rust Bullet Clear Shot.In all honesty, I have had treated other rusty metal with Rust Bullet - either outside (I live close to the beach in San Francisco) or on my old 1988 Volvo - and the rust has eventually come back. Then again, those projects were all back in the day when I might have only put on a few coats of Rust Bullet. Now I tend to go for 5-6 coats and have had better luck. All in all, considering what's on the market, Rust Bullet is the best thing I have found for rusty metal. Let's face it, they say rust is like cancer and once it's established it's very hard to stop or eradicate completely. That's why I don't expect miracles with Rust Bullet, yet I have been pleasantly surprised.

I own a steel boat in the Caribbean. I have always been a fan of Awlgrip, but as the humidty here makes getting a primer on before any flash rust occurs, I decided to try out some new products after 18 years. I got a quart of POR-15, one of Pettit Rustlok and 2 of Rust Bullet Industrial- Big mistake. My surface prep was not an issue. I sanded with 80 grit to bare metal, let it flash rust for 2 days, powerwashed it and let it dry for hours. No where in the instructions that are on the can or came with it (very detailed- I was impressed) did it mention how the paint could bubble and fail if put on too thick. I read about this later online. The directions were very clear however that you cannot wait more than 12 hours between coats without sanding and that 3-4 coats were required for marine applications. I only put on 2 coats and before I was even done applying things were not going well. This product (much like the other 2 mentioned) cures with humidty- Rust Bullet seems to "cure" the fastest. It was already getting chunky with 2 of us applying it out of a 1 quart can with 3 inch brushes! The next day the surface has transformed into a frothy looking mess. I had hopes of salvaging what was already done, so sanded it down, and applied another thin coat and waited two days. NOPE. The temps here are about 90 and the humidty over %90- the product "cured" too rapidly and there was so much air trapped in the paint that it scrapped off in flakes even after 2 days of curing. I had very high hopes reading other reviews , but , if you live in a hot humid climate, this product is a total disaster. The POR 15 also cures with moisture and was getting thick before I finished the quart, but made a smooth surface. I'd also add from what was left in each container/ based off sanding each- the POR-15 dries to a MUCH harder surface.

Brushed on easily and goes a long way. Used it on a free standing carport where the metal legs/supports have begun to rust in places. be sure to use a throwaway brush and wear disposable gloves as it will not be able to clean off your fingers or hands afterwards.
