Thanks. will check it out and post results. As to the stainless, my experience in the chemicals industry is that stainless needs to be the right grade for it to be effective. The varieties of crud on the roads, especially in the northeast, may make this a difficult quest. After all, look at the "stainless" exhaust systems that rot out. Another potential problem is that stainless alloys like to gall in the thread areas. It also dislikes bending. Would be interesting though.
