I have never lost any faith in ARX, it does what it says it will better than any product in its class.

As a matter of fact, in my own cars, I have seen ARX slowly remove varnish. But I am more concerned with cleaning ring packs and internal motor parts, which ARX does flawlessly. I don't know of many products that can say many of their customers have experienced increased compression like ARX can.

Thanks again and I will always be an ARX customer,
