Gas tank refurb, alt source?

["O'Farrell, Fergus" <Fergus.OFarrell@ngc.com>]

Not that they'll be the cheapest, but another common source of this is
motorcycle resto/refurb shops.  They would probably not want a car tank,
but when they see how small it is, they might consider it.
They coat the inside with 'sloshing compound', which is used as a sealer
as well as rust resistant coating (I think, at least).
