信頼度抜群!!
アメリカのアルファロメオのスピードショップで売っていたので信頼してました。 今迄以上に冷却出来ているようです。 自分の場合2倍位濃く使ってます。 しかも精製水を使いました。 大切な車に使うのでRED LAINはオススメです。

It was not what I expected. I applied for a full refund
To discover It was not the required Red Line "Water Wetter" I wanted, thinking half Gallon was cheaper than Two Bottles of "Water Wetter", ( I found later there is a UK shortagr of the said bottles) The Super Cool is heavly diluted and would not be suitable for my needs.
