Rust911 Use

[Colonel]

I am going to try Rust911 for my cooling system based upon the many positive posting about its use on Fordbarn. If I understand correctly, the product reacts with and solubilizes the rust in the solution so there is no need for a filter. I would greatly prefer not to remove the hoses on my radiator so drainage would be through the petcock. Let me know if this method should work. Forgot to mention, after charging the 911 I will run the engine for a considerable period of time, get everything hot, and let set a couple days before draining.
