[Mg-mmm] J2 gas tank sealer removal

[Tom Metcalf]

Bill, I would have it chemically or heat stripped and rinsed. Then it's 
completely clean and ready for Redcote - the only tank sealer we use. We 
use a nearby stripper who does the entire car for about $400 - all sheet 
metal, chassis frame, and chassis components.
