On the other hand, pop-riveting aluminium to stainless steel as a structure on the underside of the bus and then driving it in the winter with road salt is a sure-fire way to be doing that repair again soon...Brian
... possible corrosion caused by attaching alum directly to mild steel or stainless? Should it be separated by a mechanical barrier or will paint do? What kind of fasteners?
The stainless/aluminum thing, if its so bad, why do all the outboard boat engines use stainless steel bolts??

Zink Chromate is not worth crap any longer,,, EPA mandated the ZINK removed, so now is junk.>>>Dan
