If you have used water wetter, can you provide me with a quick breakdown on how to apply it. Can I use it without flushing out the entire radiator? The reason behind using it, is the rise in temps I am experiencing (engine 351c 2v) when I am idling for a good amount of time...I am doing a show in a few weeks and trying to find somewhat of a fix to get me by...Any suggestions would be helpful...
