[Tigers] Refinishing f4b Manifold

[Will Seay]

Jim,

I know what you mean about too shiny.  I had my F4b sand blasted some years
ago and it came out very shiny.  Tried all sorts of things to restore the
original cast look.  Finally used a wheel cleaner which contained an acid
etchant (obviously not for polished wheels!!).  That restored the original
cast look.  Used a hand file on the surface of all raised lettering to
bring that back to original.  Can't tell you the brand of the wheel cleaner
- probably out of business by now anyway.  I've been told that if, instead
of using sand or beads, you blast the manifold with walnut shells, that the
original texture will be preserved.  If you've already lost the original
finish to bead blasting though restoring it with acid etching might be your
only option.
