## 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.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Top of the line, best on the market.
*by N***  on May 17, 2025*

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 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. 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. Ventilated area is a must, strong odor and causes bad 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. 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. 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. Not a cheap wd40 job that lasts a season but lasts a lifetime. Highly recommended, five star review.

### ⭐⭐⭐⭐⭐ Good Stuff!
*by P***L on May 28, 2025*

This is a silver coating very similar to another popular product at a fraction of the cost...With multiple coats you can fill some pretty large pinholes.

### ⭐⭐⭐⭐ Nice for under rusted mower deck
*by J***N on October 1, 2024*

To all the criers on here and elsewhere about the product drying up in the can. I have a partial can after 9 months and it's still not dried up. You have to keep the surface clean where the lid goes back on...duh? LOL. Anywhoozal, this stuff seems pretty tough. I used it under a rusted mower deck, because inept people believe they can mow wet grass and not clean under the deck when done. Then wonder why it rust... I digress. Love this stuff, but it is expensive, hence the 4 star rating for the small amount of product received.
