Review: Top of the line, best on the market. - Five star review. This rust inhibitor paint is the best stuff one can buy on the market and even the army and navy and major architecture landmarks use it and has two genuine patent awards. Does that tell you something? It will save your precious automotive vehicles or any metal items from rusting or worsening condition. There's a lot to study about the right application and best results for this paint but I'll break it down. The photos show my cars undercarriage so in my case it is an automotive project. Use a conjunction of products from rust bullet for best results, metal blast, the paint, and clear coat. You also require disposable brushes from the dollar store, nitrile gloves, mask, overalls, goggles, PPE. Bloxygen too if your going to reseal the paint can. 1. Clean the undercarriage of the car, prep work, use a garden hose and wire brush to scrape off oil and dirt etc. Remove loose rust. Step 2, when totally dry you'll jack the car up and spray metal blast dissolving the rust and creating an adhesion to the metal so when you paint it'll stick. It undergoes a chemical reaction. Let sit for 20 min or so, then rinse with garden hose and dry. Or it'll keep eating at it. Step 3, paint in a garage indoors is a must with temp 50-80 F and no rain, 1st paint coat by brush and 4-6 H dry time, important, don't wait more than 12 H after 1st coat, it'll harden so do 2nd coat after it's dry. Filler, then sealer. Do 2nd coat, let dry, boom, ready for two clear coats next, 2-4 H dry time and when every nook and cranny is covered just wait 72 H or less, full cure time before exposure to outdoors. It'll make the metal look brand new and shiny with the clear gloss. You won't see any rust underneath. It's not that expensive and should be used way more often in a automotive world of mistreatment and any vehicle with this conjunction of paint will last forever. The paint acts as a filler, stopping the rust, it's water resistantance is unbelievable, I got a good amount of paint on my hands and the water evaporates within seconds and the stickiness is the bond to the metal so it's staying there in form so long as the car body is there too. Superior barrier on the metal, recommended to do the undercarriage first and then take car panels off, (fenders, bumpers,) and paint the wheel well areas and inner frames especially. You can do the trunk and bench seat areas too if your really into it but especially undercarriage area for winter driving. The finished surface is smooth as glass with clear coat, water just runs right off it and evaporates. Any dirt and such will barely stick on and can be cleaned easy with hose and soft brush occasionally. If you experience your project area has rusted through after painting then two options, use same color spray paint to touch up or repaint with same inhibitor paint once more because the rust was such bad shape. At most two times will do, just add more coats it'll seal off any rust. Had that happen and four total coats did the trick. Once you are done only thing to do is clean the area occasionally and inspect it. You'll never have to worry about it rusting anymore. Ventilated area is a must, strong odor and causes severe headaches so be professional when using it. It's not ordinary paint, drys like cement so cover floor with plastic sheets. Note- only pour out what your going to use in an hour and reseal the can immediately. Moisture sensitive. Opened can will last a month with bloxygen. Sealed can shelf life is 2 years minimum. Stir before use. Depending on how much rust you have or area the small 1/4 pint cans will barely cover half your undercarriage 1st coat, 1/4 PT = 6 SQ FT. A quart is plenty for 2 coats with a little extra and a pint would be enough for 1 coat. If you get paint on your hands or such use acetone and cotton ball. Removing the dry paint from a surface is near impossible. Its important to know the temperature limit too, only paint surfaces that won't exceed 450 degrees, car body areas yes, exhaust system and lines don't do or any engine bay areas either with risk of damage. Use high heat primer and paint for those areas. My project turned out phenomenal and saved my show car that I put so much time and effort into and yours can too with this wonderful paint product. If you want the best and are willing to put time and effort into it this paint is top of the line. Rust Bullet is the only product with two patent awards and no other products do. Not a cheap wd40 job that lasts a season but lasts a lifetime. Highly recommended, five star review.
Review: Fantastic paint. - So far I absolutely love it. I did it when it was a little bit too cold but it still worked out fine. I was amazed at how tough it is when I was sanding to add a 3rd coat. The clean up was ok for a natural Bristle brush in thinner. It says xylene but I just used regular paint thinner and it did ok. I got it on my skin and it was a nightmare to get off and I had to wear off most of it. I will update my review after I have had some time to see what it does and how long its gona last. I also used black industrial enamel as a top coat.

## Questions & Answers

**Q: Is this product able to be welded through?**
A: Hello:
The extreme heat involved in the welding process will disintegrate Rust Bullet, and most other coatings. If welding is necessary after Rust Bullet has already been applied, then it should be removed prior to welding and reapplied afterward. After curing, all Rust Bullet coatings have a service temperature of 314F (157C) continuous and can tolerate maximum temperatures up to 662F (350C) for up to 72 hours.

**Q: does it come in white?**
A: Rust Bullet only comes in silver but had a very durable white top coat.  I have used both the black and red top coat and it is very durable.

**Q: What kind of paint would use for finish coat.**
A: All depends on what your painting. You could go on the cheap end and simply use rustoluem paints, or buy professional autobody primers and topcoats. I plan to topcoat with epoxy primer from a HVLP paint gun and then topcoat with the color I plan to paint the car i used the rust bullet on. I only used the paint on areas that are mostly hidden after final assembly, but want everything the same color.

**Q: no se reduce la pintura**
A: It is not recommended to thin Rust Bullet Coatings. If you intend to spray with an HVLP, you can use a 2.0 tip. Rust Bullet is ready to use right from the can, and you would want to adjust your equipment as opposed to adjusting the coating. Once thinned, it in not the same formulation and will not work the same as when it was made. You can use Rust Bullet Solvent or Xylene for clean-up of equipment. 

No se recomienda diluir los recubrimientos de bala de óxido. Si tiene la intención de rociar con un HVLP, puede usar una punta 2.0. Rust Bullet está listo para usar directamente desde la lata, y usted querrá ajustar su equipo en lugar de ajustar el recubrimiento. Una vez diluido, no tiene la misma formulación y no funcionará igual que cuando se hizo. Puede usar solvente de bala de óxido o xileno para limpiar el equipo.

### ⭐⭐⭐⭐⭐ Awesome product!
*by K***. on October 12, 2024*

I used this on the hood of my 1972 VW super beetle and I'm about to apply it on the deck lid and roof. I used locktight rust remover gel on the small amount of rust spots, followed by a mild degreaser to wash, then applied rust bullet. It brushed on smooth, left no brush marks, covered beautifully and actually looks nice. I'm confident that this product will protect the metal while also creating a nice smooth even surface to paint over. I've had it on my hood for over a month now and its holding up well. The can is bit of a pain to open but, I'm 60yrs old with arthritis in my hands and I managed to get it off without spilling any so.....regardless of the 5 mins it took to pry it off, once I saw the performance of this product? I'd gnaw it off with my teeth if I had too (almost) to get it open the product is worth it. Don't shake the can, leave it upright, pry open and stir it well to insure you get no bubbles, and brush it on your classic vehicle with confidence. I just ordered more p!us a can of rust bullet whiteshell and a can of their blackshell which I plan on using inside and outside of my vehicle. You won't find a better product, don't let the difficult can scare u off this great product. Remember, if it gets bubbles while opening, let them dissipate before application, stir until mixed well with no bubbles for a perfect finish. Enjoy, and good luck with ur restoration project.
