Very impressed with product. Perfectly sealed my two valve rocker covers on my big V8 turbo instead of using gaskets. I made a sample dab the size of a bottle top and half inch high onto cardboard and let it set overnight and I was amazed how well it can compress without destruction and still return to its original dab size. Will definitely use this gasket maker again on my future engine repairs.
