Not sure what the case is made of. However, I do use anti-sieze on my plugs
in both the car and boats. I have never had a plug rust problem.

Have they got the platinums in stainless steel now? I'm a little leary of
a
plug I don't have to change for years but is not stainless.

I have never heard that one before. I personally would not use anything
but
them. If you install them, you will probably never have to change them
again. Probably why the mechanic does not like them because he never
gets
to do the job again.

My marine mechanic recently told me not to use platinum plugs in my
boat
(Volvo Penta 5.7 raw water cooled). He says that they run too cool
and
tend
to get fouled as a result.

What is everyone's opinion on this? Has anyone experienced problems
with
platinum plugs??
