I’ve been using the Red Line WaterWetter Super Coolant in my race car for a few months now, and it’s made a noticeable difference in engine temp. I really appreciate the 12-ounce size in this 12-pack; it’s perfect for my needs. If you’re into performance driving, this is a solid choice!

Not what I expected, faded color
Ordered the Red Line WaterWetter, and while it seems to work okay, the color in the bottle looks different than what I saw online. Also, I had a small issue with one of the bottles arriving slightly damaged. Might be fine for others, but I’m not thrilled.

Decent coolant, but shipping was slow
The Red Line WaterWetter works well in keeping my car cool, but I had a bit of a hiccup with the delivery. It took longer than expected to arrive, which was frustrating. However, the coolant itself performs as advertised, so I'm happy with it overall.
