Re:[T3] Gauging metal/thickness


RJ - Rusty (?) aluminum....don't think that will happen....8^)

As for the lower grade steel....don't know, but during the mid
seventies many American car companies looked at deleting the
finish primer coat of paint on the car to cut costs.  This lead
to faster rust out and peeling paint, especially on light color
and metallic cars.  Turns out the conductive primer (e-coat) put
on before the primer was very sensitive to uv light.  The finish
primer would protect this e-coat from uv, but when the finish
primer was deleted the e-coat would breakdown under the uv light
and the top coat would not stick good.  Very messy situation...
