Hello everyone, I saw this in a store at one point and forgot about them until today. Was wondering if anyone used this and can report back on results, any results. Stop Smoke: Stop Smoke - Nulon Products Australia Engine Stop Leak: Engine Stop Leak - Nulon Products Australia There are other products there and look "good". They look all right on paper, not so sure on the actual use of those. I must say, I'm not attracted at all to pour some of that in the engine.
