I have used their products with in the past year. 707 is okay. It is the basic fleetwash. It is not the best, nor the worst. They also have a premium chemical that is a little more expensive that I like better. I always had a problem getting a hold of it. The local distributor would not stock it too often because I was the only one using it.
I prefer the Delco chemicals. r-109 and DNB-1433. They are a lot better, especially the 1433.
