Anybody use this product? How effective is it? Thanks in advance.

 

I am very skeptical when it comes to additives and i always need to be proved wrong. I heard about this red stuff and i read all the info and saw the video and then decided to invest in some. Got it, added it to my teg and was eagerly awaiting temps to go down considerably...alas they did not. Did not feel any difference.. the temps prob went down some but not enough to make the hood cold after driving for hours. If your expecting to feel a difference youre prob not but then again it is better for your engine.

 

Dont expect a drastic decrease your temp, I've put it in all my hondas/acuras and I do see a difference, its not much. But then again you have to remember that your adding it to a radiator that has thousands of miles on it and the water wetter is susposed to bond to the metals surface and make the water dissipate heat easier, it has trouble bonding to the surface if the surface has rust/dirt on it.
If added to a new radiator, you'll see much better results.
