1.0 out of 5 stars FAULTY PRODUCT
By Clint Nichols on May 21, 2019
Finally got around to use this after sitting in a box in my office for over a month (the weather outside turned cold right after I bought it). And all that sprays out is a nasty oily spray. NO black, not even paint. After REPEATED and EXCESSIVE shaking still the same results. Unfortunately my ability to return expired a week ago. Don't bother with this.
I have included photos of the spray that comes out of it. You can't see it because it is a clear-ish oily film, but it is sprayed all over the area in the picture. I sprayed it heavily on the brown-paper covering my running board in the hopes that it would actually start spraying paint. No dice.

1.0 out of 5 stars Did not spray, will not buy again.
By H. H. on January 10, 2019
Granted it was cold (40F) when I tried to use it........I sprayed a small spot on my 100% rusty steel wheelbarrow.....and it never turned black. I had soaked the can in 130F hot water from the tp........and brought it out in a bowl with the water. Very disappointed and a complete waste of money for me.

1.0 out of 5 stars Do not buy!!!
By Raymond on September 8, 2018
This product is nothing like what it says it is. I needed rust converter for a project and ended up spraying what seems to be clear coat. Completely ruin the piece I was working on and had to spend three hours to try and remove it all. Don’t buy definitely will ruin your project. Complain to Amazon and they are investigating the company because the product is not what it says it is.
