[oletrucks] further de-rusting

[mark@noakes.com]

I got a comment from someone on one of my lists that the electrolysis process 
should not
be used on any safety-related items like steering arms as it may cause hydrogen
embrittlement.  I was looking for something rusty to try this out on and 
happened across
the steering arms first...apparently not the best choice...

I would not have expected this to be more than a surface effect.
