Hello All:
Let me share an experience that may be
relevant to the torsion bar question. When restoring my 56 Fury, I took
the rear springs off and saw that one of the bottom springs was cracked. I
took both sets of springs to a spring shop and had two new bottom springs
made. I did this so they would match and be of the same
strength.
I then took all but the bottom or
main springs to be blasted and powder coated. I was not sure what the
heat of powder coating would do the springs, so did not take any chances
and painted the bottom springs. Today over a decade later all is well
and I cannot tell the difference between the powder coated and painted
springs.
Therefore, my thought is to paint the
torsion bars as nicely as you can. No one will be able to tell the
difference and you can rest easy that you probably will not have to touch
them again.

I agree
with all except the sandblasting. Sandblasting does leave a rough
surface, actually too rough for immediate painting, which I suspect could lead
to stress risers. I would prefer media blasting, maybe walnut
shells. Smoothing would be on the menu too.

I don’t have
much experience with torsion bars other than that a 2-year old bar broke on
my ’61 Valiantmy first new car. As a corrosion engineer, I noted
that the coating had been nicked and the salt of Omaha streets had worked on
the exposed steel and allowed a crack to start. Nice thing about
torsion bars is that the ends just slid out and enabled the Valiant putt on
down to the Chrysler dealer for a warranty replacement.
If I
were to restore a torsion bar, I’d have it sandblasted, polish out any nicks
or cracks, have it Magnafluxed for cracks, spray it with zinc-rich primer
and follow with a coating of POR-15 or something similar. The zinc in the
primer will give you some protection against future nicking of the
coating. You could also have the sandblasted and inspected bar
lightly galvanized and then powdercoat it. That would provide
excellent corrosion protection which you may or may not needdepending
on your planned use of the car.
The opinions of others more
experienced is welcome.

Subject: Torsion bar re-coating/paint dip, or powder
coat??
I've been perusing the fwlk and imperial web board, googling,
etc, and I can't find anything that helps me decide whether or not the
original style thick paint is better than powder coating (or even if powder
coating can withstand the twisting stress).
I have my torsion bars
off and will be wiping them down and inspecting for chips and rust this
weekend. Next week or so I will be sending off various front
suspension pieces to be media blasted and powder coated....but I'm unsure
what to do with the torsion bars. Can they be blasted and
treated the same
way?
Thanks,
Lou
