Product Description

Mar-Hyde One-Step Rust Converter Primer Sealer chemically reacts to convert rust into a hard, black primer sealer. Apply One-Step on rusted surfaces and rust is permanently converted and ready for primer and topcoat. One-Step Rust Converter Primer Sealer is a water-based latex containing rust modifiers, which is designed for application directly over tightly bonded rust on iron or steel. Also proven effective on new degreased or mild steel where flash-rusting has occurred. Shortly after application, the rusted surface will change form white to purple to a stable black coating. A uniform black coating indicates the complete conversion of the rust; white streaks or remaining rust indicates that an additional coat is required.

Well, my 2005 truck had a lot of surface rust on the frame, so I thought I would nip it in the bud. I read a lot online about what to use and decided to go with the mar-hyde rust converter.

I used about 2 full cans to rust convert the frame, drive shaft, axles and hitch of 1 mid-sized pickup. I will probably go back and touch up with another can. I tried to avoid spraying on plastic parts, but it doesn't say anywhere that it will hurt plastic or rubber parts. It does say not to spray on any surface that exceeds 200 degrees, so I definitely avoided the exhaust and engine. The body itself looked perfect so I did not use any on the body. It seemed to do a good job. By the day after I sprayed, the rust had all converted to a smoother darker finish.

On the down side, the fumes seem very noxious. I used it outside, on a slightly breezy warm day and the fumes were still strong, especially if you got in the "cloud." I would only use it outside and preferably with some sort of mask and away from children or pets.

I am planning on coating the underside of the truck with fluid film also, but I have not done this yet. I am not planning on painting the frame. Its been about 2 weeks since I performed the initial treatment and I have had no problems.

Well, there is my story about mar-hyde. I am not an expert, but there is my experience. hope it helps someone.

Been using One-Step for years. It kills rust dead in its tracks. Wire brush the loose rust and spray it on. It converts rust into black paint. I do recommend topcoating over it. Typically I would use One-Step, then primer over that, then top coat it. I've used it on cars(frame and body both) as well as tractors.

I am still experimenting with this product. First time I used it the product flaked off in 3 days. I am following instructions but it is no adhering. I did read online that product needs rust to adhere so I let it rust up again and will try again with the One-Step Rust Converter Primer Sealer, 10 oz. aerosol.
