Review: FDC rust converter ultra worked great for me. - I used this on an old car body that was glass bead blasted and it worked great for me. I applied it uncut with an undercoating gun. It went on pretty good considering the cheap gun I bought because I couldn’t find my old good one. On the inside, it went into places that blasting couldn’t get. It turned purple, and after 4 days, I sprayed epoxy primer over everything and it adhered well. I live in Arizona where the humidity is very low, so consider your humidity levels, you don’t want to trap moisture between your metal and this stuff. This stuff is good for existing rust, not so much for preventing rust from trapped moisture, or your finger prints.
Review: Rust eraser works well. - Pleased with the results. Undercarriage is new looking now.

## 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.

*by K***R on February 7, 2017*

Hard to give a complete review as I really would need a few years to see how it goes. I will give a review of my current experience. The shipping was quick and the product was at my house in just a few days. I am restoring a 47 Chevy truck and there is quite a bit of surface rust and pitting. I completely sanded the door down, took a wire wheel to the pitting and finally sandblasted. It came out really nice but there was still some dark color in the deeper pits. I painted this product on with a brush. Almost immediately it turned all of the metal it came in contact with to a dark purple. Once it dried, it was almost black. Give it a day and put on another coat. After a few days I took the DA sander and went over the whole panel again, only leaving the Rust Converter in the pits. I cleaned it all up and did my body filler over top of the RC. Sanded down really nice. At this point I have primed but nothing further. After a few weeks all looks good. I really think the RC is going to help deter the rust from coming back. It is also easily sandable by hand and comes out really smooth, ready to take primer directly on. I'm overall happy with this product so far. But in all honesty, it will need to be painted and in place for a few years before I know it is going to work as expected. Thanks.
