The engine bay is now reasonably clean after many hours with a wire brush and warm soapy water. Everything above the seal flange will be painted with the rest of the bus, everything below will wait until the bus is mobile since I can then access the area more easily by driving onto ramps. Many other items were tidied up, mostly related to the front floor area which I had tacked into place after I first got the bus but had not been finalized. Scuffing of the exterior paint and rust treatments were done in anticipation of primer tomorrow.
