Don't dip that in acid just yet...

[Allen Patterson <kormanfastbmw@worldnet.att.net>]

There's a far better way to get the body, frame, etc. clean without the
drawbacks of acid or chemical dipping. It's called media blasting.  Just
like sand blasting, except fine plastic granules are used.  This gets
rid of all paint, rust, corrosion, etc. WITHOUT imparting any texture to
the metal or warping panels.  Most places charge by the hour.   We have
a place here in NC that does it, check your local yellow pages before
you dip.
