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.

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.

Wear rubber/nitrile gloves, you'll need them. Having a fine nap paint pad may be handy if you don't have tons of gloves. Product is thin and coverage is excellent. Thin yet somehow viscous enough to not drip a lot. Applied with brush on rusty OME leaf springs. Everywhere that factory finished remained it turns whitish. (Manufacturer recommended using oil based finish to protect once product cures in 48 hours) like any job, prep is key. your mileage may vary. Everywhere there is rust or bare metal turns a dark purple/midnight within 30 minutes. It foams a lot so wouldn't recommend using an air sprayer. The cleaning type sprayer (Windex bottle) would be good on "stream" for covering large areas of truck frame or large projects.When foaming occurs in project material; sampling rub with gloves hand or use fine napped paint pad or microfiber cloth. Used about 4 oz. to cover all leaf springs twice over. Next morning product seems cured with no off-gassing. Time will tell longevity. I tested rusty bolts, a shovel, some plate steel. Un cleaned truck frame, product was not picky ... Works on just about everything. Much easier, cleaner, better coverage and adherent, non-fuming alternative to POR15

I just spent 3 long days peeling a 20-year-old commercial bedliner spray job on my F-450. Part of it had come loose and the rust was starting to be too much to ignore. Peeling The remainder with hammer, chiselwith and half dozen wheels of paint and rust remover with a grinder. The job absolutely sucked as each morning the entire grinded area was all rusted over again. I use the product over the really bad rust pitted almost through areas and it did such a good job even on the exterior parts that was just bare metal I ended up laying this product over the entire bed before doing a new bedliner rolled over finish. The proof was instant as the next morning there were no rust anywhere. The product does say wait 48 hours and it confirmed the effectiveness against rain and morning dew. I was quoted $1800 to respray a bed liner after I did all the hard work so I ordered the herculiner kit. I like this product so much I went on to use it on top of a 2003 expedition roof and then use the same bedliner finish on top of that roof. I have been to multiple finishing shops charging me thousands of dollars to stop the rushed holes on the old Ford roof and All I did is waste my money with them. This product along with roofing fabric over the holes of rust and the bedliner finish renewed my SUV for another 5 years. Can't beat the naturally aspirated v8s that has been maintained so why you lose a vehicle over rust that now can be taken care of with this phenomenal product. I am now using this chemical in a spray bottle to go underneath my truck and spray the entire frame along with the drive shaft and anything else that looks rusty. Every 6 months I go under the truck with a can of rustoleum rust converter and it's gone within months. This product is for real not just surface garbage. I'm starting to use this as the primer coat on anything that has metal.

Living is Wisconsin you will never win with rust. Tried many different ways and eventually the rust comes back. Also tried a few different final covercoats of different paints over this stuff and rust came back.

I haven't had a chance to paint do any body fill or paint yet but this stuff definitely stopped the rust in its tracks. I had to access the inside panel as well as the outside panel in order to stop it from rusting on the inside out but it was worth the hassel to get the rust to stop travelling up the side of my truck.

The thing I like the best about FDC Rust Converter Ultra is that it really works. I also like that it is water-based. I apply it with a big paintbrush and it soaks into the rust, seals it, and stops the rust. It's a good value for the price and a gallon gives you plenty to cover a huge area. Preparation is easy too. You just have to knock off the loose rust pieces and then you can paint this right on. It turns the rust into a black coating that is as hard as rock. Definitely stops the rust in its tracks.

Customer service is A+++ Right from the start when you order, they email you to thank you for supporting a small familly buisiness and how they're proud and confident about this product. I received my gallon couple days later and started right away on my rusted truck frame. It's got a white milky texture and goes on great with a paint brush. Let me say that a small amount will cover a whole lot of square feet of rust area. Within seconds of contact, the rust chemically turns black as the product dries. Applied 3 coat everywhere and it did a great job. I just hope it lasts a long time. Great product!

The product did an OK job. It wasn't magic, and there are a lot of tricks to using it. I'm pretty sure I don't know all of them. However - I believe it needs to be warmer the recommended 10 deg C. I tried to finish one day, painting as the sun was going down and that metal didn't convert - or converted just dots (pic 4). Worse yet it seemed to create a barrier that made it not convert well on additional coats. The air temp was still good, but lack of sun, or maybe nighttime moisture gave me issues. It took at least a week for the paint to fully blacken regardless of problem areas or good ones. It also appeared to convert lightly rusted metal better than heavily rusted metal (1st pic is really noticable). I sprayed it and brushed it on, and neither appeared to be better than the other (although the brush could get into different places, the sprayer was faster). Oddly enough pics 1 and 3 have 3 or 4 coats. Pic 2 and 4 is a single coat. Coverage was about what they said for a single coat. I read another review that talked about it bubbling from the heat of the sun. That worried me a bit, and I didn't read it until my first coat was already on and I was having problems. I might test it on some scrap metal and I'll update if I do. I did email them and they responded right away, although the advice wasn't as helpful as I'd hoped. I didn't follow up any further so maybe there was more information there if I continued the conversation. Given my options of priming over the rust (which was mostly surface rust similar to pic 2), sanding or sandblasting, I'm happy to have this coating on. Oh, also I wasn't careful washing my hands and I may have stained the sink a little (purple)- but that'll be our secret.
