Anyone ever try using permatex spray on gasket remover for carbon removal? I had a old dirt bike piston kicking around that had real heavy carbon fouling on the top and just to see how effective my current carbon remover was I wetted a small area with it and let it sit for a few minutes and tried rubbing it off with a patch. It hardly even touched it. I also tried wipe out and sweets and had about the same result. I had the permatex on the work bench and decided to see what it did and sprayed a small area and only let it soak for half a minute and I could wipe the carbon off right to the bare metal with ease. It turned it to a paste in short order.
