Jeff,
Many owners seem to go the POR-15 route. If you want to powder coat then
the parts need to be bead blasted to optimize the powder paint adhesion. I
went this route for my frame-off restoration but that's because everything
was taken apart and bead blasted, using the cabinet in my employer's tool
room so it cost nothing except hours on my feet. Powder coating was not
that expensive at the time (2002-2003) - the entire chassis cost $250 and
all of the black metal throughout the car was another $250, done in either
semi-gloss or gloss black.
I do not recommend pressing off the axles from the vertical links unless you
want to replace them. I tried this once and it took over 2000 pounds of
force on an industrial press before the thing loudly popped off like a
missile into a large blanket placed underneath. You can mask the surfaces
that you do not want to bead blast and paint. Powder coaters use a special
masking tape that can withstand the heat from the baking oven.
Trunnions should not be tight unless you are referring to attempting to turn
the vertical link on the car while up on a jackstand. In that case the road
spring is adding alot of downward tension without the weight of the car
compressing it. And make sure you use the proper weight oil, not grease,
inside the threads before threading on the vertical link. Thread the
trunnion all the way on then back off to the first working position (as if
on the car = axle facing out, trunnion aligned with axle). It's also a good
time to make sure the lubrication channel in the vertical link threaded
section is clear. Sometimes it gets clogged when grease is used instead of
oil.
