I think a dedicated thread to rust removal would be great. F9 is really amazing. These stains were on vinyl siding for 8 years that we know of. The home owner was standing next to me when I applied F9. F9 is absolutely amazing! The homeowner couldn't believe his eyes! I couldn't believe it. Rust removal! Separate thread! You heard it here!
