Review: Satisfied - Seems to work well. Sprays pretty well.
Review: Impressive! But it needs to come in a quart size too - My 2014 Tacoma was developing some rust spots underneath, so I tried this rust converter. It worked amazing well! It looks like milk and does not have any nasty odor. I simply brushed it liberally on the rusty spots on the undercarriage, and within a day or two I noticed the rust was gone. No scraping or sanding required. I also did not bother painting over it afterward as the rust was all surface level and this really took care of it. Unfortunately, I only used about 1 quart of the stuff so I have a ton left over... if it came in a smaller container option that would be great. But still, for the price it worked great and took care of the problem, so I highly recommend.

## Questions & Answers

**Q: How many square feet of coverage is expected with 1 gal? I have a scraped steel trailer bed with surface about 6 x 18 feet I want to coat, then paint.**
A: I used 1/2 of the gallon on a 9x8 steel flatbed. 2 coats. Worked amazing. It converts whatever rust it touches to a back hard substance. If you have rust scale it soaks it up and turns hard.

**Q: What is the shelf life of this product once opened?**
A: There is a product called "End All Rust that I purchased in 2003 and just used it again this year 2023.  A little clabber at the bottom of the jug, but it did a great job!  Still working after 20 years.  I can't see why this FDC wouldn't last at least half of those years.  Rust converter is rust converter.

**Q: Can I apply this to a wet surface?**
A: It applies just fine on a wet surface, but you're diluting it.  That said, as always, you would probably have better results on a prepped surface.

**Q: If used on frame does it have to be painted?**
A: No it doesn't. When cured, it will leave a black polymer finish that's fully sealed & waterproof.

If you decide to paint it afterwards, use a high quality oil based paint.

### ⭐⭐⭐⭐ Works well if not painted over doesn’t work at all if painted over
*by P***L on July 26, 2024*

Works well on vehicle frames and axles looks black in sunlight and normal lighting but shine a spot light on it and it turns clear which is dark brown when it’s over rust. How often do you shine a 10000 lumen light at the undercarriage of your vehicle though lol. It works when left unpainted over for some reason if you paint over it even after waiting for it to cure the rust eats right back through with a week. Haven’t figured that one out something to do with chemicals or oxygen I don’t know. The nice thing about it is if you get it on a surface that doesn’t have rust on it it’ll dry clear and then wash off that surface when it rains which makes prep practically nonexistent. I still wouldn’t get it on my paint if I can help it. You don’t want to sand to bare metal either it won’t work it needs rust to react to. It’s a chemical not a paint. Just sand it down to surface rust and ably.
