We just love our oil spewing planes.
What we don’t love is stepping in oil stains and dragging those stains inside the plane. My air club has been housed in the same concrete-floored hanger since the mid 1960s. We’ve used absorbents and a broom since then. Now we use ReKRETE. These pictures show the result of ReKRETE after the first use. It provided remarkable results. We keep some handy now to sprinkle on any new stains and the hanger floor looks a thousand times better.
