Rust in the block?

This link shows the Rust 911 concentrate which makes 16 gallons. If you look at the Rust 911 website its shows a radiator/ cooling system flush as a separate product. Are these one in the same? Can the concentrate be used and achieve the same results? The concentrate states it is to be used as a soak or immersion. Nothing about circulating through a cooling system.

Just trying to determine which route to go. Only want to do it once.

I have used the RUST911 concentrate on several vehicles with excellent results.

You want to use the Rust911 Concentrate. Mix per the instructions, fill the system and drive it around for a few days. The heat in the cooling system will help make the stuff work faster. It will not hurt anything in the cooling system. You may have to flush and repeat several times to get all the rust out if the system is really really badly rusted up.
