Consider:
1) Penetrol

Penetrol sounds good, but it seems to be listed as a paint additive,

as a protective finish in its own right. Have they changed it, or is
this the same stuff?


I could not say. I bought mine about a year and a half ago. I got the hint
from a metal sculpture discussion group where they seemed to like it. I have
been using it but do not have a track record over years to show how good it
is long-term.
