ACF-50 is probably the best stuff I have used. Highly recommend anyone to give it a try. Like I said earlier about fluid film, I like it for the fact it works but I don't like how sticky and thick it can get. From that video XCP sounds like fluid film. So from my own experience with these two products, I will use ACF-50Here's an interesting video showing a guy doing an experiment with ACF:
Another good thing about ACF-50 is it can be used to spray down electronic connections too.
