Probably the most important question to answer is; what makes corrosion between rubber and aluminum?  The other is; how to avoid it?  
Although, I have put this question up more than once within a year, nobody even attempted to try to answer it, but ONE.
This list is fighting and dreading this symptom the most, yet there is not enough knowledge to know how to stop it.  
Is there more than ONE out of the hundreds of members who knows, or at least think he knows?
Anyone?
