Easy to use
This is my first time working with this product application and use is super easy. I will be keeping an eye on this because I'm using it for auto repair on my baby. It dries pretty quickly

No mess. Little prep. Great coverage. Bonds well
I wish I could leave it 4.5 because some spots are not fully converted and may require second coat. The product is very easy to appply. I can’t touch for the durability but by far this is the least messiest and easiest to apply on rusty parts. Requires minimal prep. Can’t wait to see how long it will last. Great product.

Goes further than you think
Did a great job. One gallon will cover the frame of a 2009 Chevy 2500 easily.

Waste of money and a waste of time - rust is still there - worse than it was
I honestly don’t know what all the great reviews are about. My husband followed the directions exactly and it had zero effect on the rust. We have a 2011 Tahoe that developed rust bubbles that were coming through the paint on the rocker panel of the passenger side. After reading all the great reviews of this product, he ordered this and applied it with a brush. That was last Fall 2024. Fast forward to Spring 2025 and the rust had worsened. He again applied this product and here we are December 2025 and looks like we are taking it in to the the body shop to get a new rocker panel. Maybe we bought time or we wasted money and our time with messing with this. Either way, we do not recommend spending money on this product. If you have rust you have to remove the rust completely or it just keeps coming back - bottom line.
