Carwell is either the manufacturer or the US distributer of the products known as T-40 and T-32 as sold by Krown in Canada. Carwell is in NY state, and has at least two shops doing rustproofing. I gave them a call and bought a gallon of T32 and a gallon of T40, as well as their spray gun. I have the door panels off of my 82 MB, so I figured it was a good chance to get some new rustproofing in there. I was always under the impression that Krown was lanolin-based, but it is not. Im also surprised to see that sulfur oxides come off of this product when heated/burned. Still, the results speak for themselves. So it is easy to get "Krown" products to DIY here in the USA.
