| All, Is the leaching of chemicals out of seams from the older acid dips, 
or the newer dips that are electro-chemical in involve un-plating the 
rust off the car by alternately turning the car into a anode and cathode?

 When a body in white is welded up the metal is all bare. then after thewelding is complete it is immersed in some sort of primer coating.  The
 coverage achieved inside hollow panels (like sills) is probably not as good
 as one would like. I have had experience in this area of vehicle
 construction for General Motors. If the (usual goo) is applied well inside
 the sills and in the dogleg area behind the doors then it will be at least
 as good as what BPSL did.

 Has anybody had their MGB tanked/dipped in the last few year?  Any price
 insight?  Only thing that worries me is that it would, in theory, remove
 all the paint/primer from within the sills/rocker panels, which would
 leave them succeptable to rust.  I could spray in the usual goo, but
 that wouldn't be as good as primer and paint, would it?
