Review: THIS one actually works! - I have tried a number of 'so called' rust converters in a variety of applications. The most difficult is when you have heavy farm equipment that is well rusted. The real problem is when you wire brush the steel with a heavy duty SS wire wheel using an angle grinder, you cannot get to the bottom of the rust pits. This is a big problem because if you don't get the rust out of those pits all the work is for naught because it will just rust through again in a year or two. So, my objective was to find some way to fix that problem. To start with I am a chemist so I understand the oxidation process and the difficulty of getting that under control. Simply put, you must intimately coat the entire surface of the metal with a good oxidation resistant primer. Intimately - meaning there can be NO rust...not even a little tiny bit or it will just rust through again. After using various rust removers I found that none will get down into those rust pits and completely remove heavy rust - NONE. Some worked fairly well on flat smooth metal but NONE would remove the heavy rust from the bottom of those rust pits. Many were 1/16" deep so even a wire wheel can't get into them. And, I'm not about to grind 1/16" of metal off of 1/4" plate steel. Next, I went to rust converters. There are a number of these on the market. One of those that was highly rated on the internet would work in some areas but not in others. In some cases it actually generated copious amounts of an orange-ish corrosion that was self replicating once I started it with that 'highly rated' rust converter. I was not impressed. The last thing I tried was the VHT rust converter. Frankly, I didn't have high hopes. However, this stuff did exactly what was claimed. Where there wasn't any rust it simply went on as a clear primer...and in those areas it bonded very well. Where there was heavy rust...especially in the bottom of those rust pits...the rust converted to a very hard black material (I believe it is iron sulphate)...in any event it is 'hard as nails' and actually much harder and, it prevents future rust from forming. This is amazing stuff and I recommend it highly. Note well, the can suggests more than one light coat to make sure you get everything covered. Because of the nature of the problem I was dealing with, I first put on a heavy coated to make sure the heavy rust in the bottom of those pits was completely saturated. Then I would sand the surface to make sure it was smooth and give it another light coat. Then, for added assurance, I used another primer available on desertcart called self-etching grey primer by Rustoleum. This is also a great product. I really like it's leveling and sanding properties. Since then I learned that VHT also has a self-etching primer, so I will try that soon. Finally, I finish with a couple coats of a good quality spray paint. I ran experiments repeatedly on all combinations of these and found that the VHT rust converter followed by the self-etching primer provides excellent rust protection and very good bonding. Be sure to follow the instructions because with these reactive materials you must apply the next coat within minutes to insure the layers react to one another. This maximizes the bond and prevents inclusion of any foreign material (including moisture) that could initiate rusting later on. From my experience, THIS is the best product on the market. Also see my comment on one star reviews under the question about how Rustoleum and VHT rust converters compare. PS Never try to do this kind of work on a foggy morning where moisture is condensing on surfaces...you will be wasting your time! UPDATE 9/6/2016: It's been almost two years since my initial experiments and I received a question from Sarah "How has this held up?" Very good question and a timely one as well...now, first a little background; I have a John Deere 950 with a 60" pull behind mower. The top of that mower deck where the leaves tend to set and hold moisture was badly rusted. However it was NOT pitted like the back blade. I sanded the mower deck down to bare metal, primed it and painted it using John Deere primer and paint. That job was done 2 1/2 years ago and I did NOT use any VHT rust converter. [See first two photos.] Rusted right through the new primer and paint. This mower is covered during winter months. Now the 'back blade''; this is where I used VHT rust converter. I decided to just try it out on one side of the top of the back blade. I've still done nothing to the other side. The third photo show the result of wire brushing, VHT primer, Rustoleum self-reacting primer and then the final John Deere green paint. Almost two years later it is flawless...no sign of rust. And remember, this equipment sits out in the elements all year round. Fourth picture is the other side which I've done nothing to...that is the way both sides looked before I started. Rather an impressive testimony to the combo of VHT rust inhibitor and Rustoleum self-reacting primer before painting!

## Questions & Answers

**Q: How does the VHT Rust Converter compares to the Rustoleum Rust Reformer? Thx.**
A: This is an interesting question.  I tried both...side by side on the same area on heavily rusted and pitted farm equipment 1/4" steel.  There was absolutely no comparison, the VHT worked the Rustoleum did NOT.  I like other Rustoleum products but their rust converter just doesn't cut it.  VHT rust converter is outstanding.  However, I was looking at the one star reviews and was wondering what those folks did differently than what I did?  Some claim the VHT doesn't work.  Something must be different!  The only thing I can imagine is that they used it differently and there are two possibilities here.  To start with, my  problem was about the worst case scenario I can imagine.  Deep, 1/16" rust pits that even a SS wire wheel can't get into.  This is where a little common sense goes a long way.  After wire brushing the best I could, there was still a substantial amount of rust down in those deep rust pits.  So, rather the follow the directions on the can (couple of light coats)...which would never saturate the relatively thick rust in the bottom of those pits, I started with a first heavy coat...heavy enough to saturate the rust in the bottom of those rust pits.  All the rust pits turned black while the freshly wire brushed steel surface remained clear.  Then, I sanded the surface and applied another light coat of VHT rust converter.  Then I covered that with self-etching primer.  THAT works great and you are now ready for painting.  Excellent bonding and no more rust!Incidentally, I ran a number of tests over a period of several months, exposing the surface at various stages to water and time.  The process I just described worked best.  Be sure to follow the instructions regarding timing.  These self-reacting materials must be applied within minutes to insure the layers bond together well.  So, to answer my own question...in some cases the user may not have applied enough on the FIRST coat to saturate the rust.  In another scenario, perhaps they didn't follow the instructions on timing.  Just my guessing as to what they might have done wrong.

**Q: What is the estimate of coverage on average utilizing your own experience? Thanks.**
A: I generally use this for my vehicles, specifically the under side, where rust begins developing. I would estimate 2 cans would be enough to spray the under side of an entire mid size vehicle. It seems to work very well.

**Q: I want to use this as under coat but I want the "converted rust" to turn black as suggested. Does this product actually turn the rust black? tnx**
A: yes the rust turns black but if there is no rust it stays clear I think that it is a good product. I think that you will have to cover it up with some thing else though like a spray bedliner might work.

**Q: I have a rusty iron engine block that im goinng to paint, should i use this product before painting? Note: engine heat is 450F to 600F, thanks**
A: No. This isn't your usual VHT product. It only rates to 200 degrees. Not like their Flameproof products.

### ⭐⭐⭐⭐ Decent rust spray...just may not be the best!
*by T***R on February 3, 2025*

Decent...and I have purchased a few cans of this product. However now I'm seeing other products that may be better..maybe? I still do get some permeation of rust and although it isn't like it originally was, it just means I have to prep and repaint some automotive body panels again. Good price and simple enough to spray on, but after a few years there might be something else that is even better.
