some high-heat paint should do the trick, but it will still rust from the inside out.
I'm buying a used exhaust system from california and it's going to be exposed for the first time to a harsh Minnesota winter. Is there anything at all I can do to ensure that it doesn't rust out right away? Can I spray some kind of high-heat rust inhibitor on it or something? Anything?
Thanks in advance.

Yep, When I put the new 530i muffler in my 525i, the original muffler was completely rotted out internally. Yet it looked nearly new on the outside.Originally Posted by Dr. evil
Hitting the inlet of the muffler on the concrete, piles of crumbling rusted metal pieces came pouring out.

So, in conclusion, the answer is: No, there really isn't much I can do.
Thanks anyway.

I read once all e34s had plastic tanks. It is hard to tell as it is covered in sealerOriginally Posted by Jehu

Is it rusting from the ooutside in or the inside out? Usually the sealer cracks (from abusive driving and/or abusive roads) allows water in and then rust can occur, I expect that the tanks would be at least zinc-plated, so rust might be an indication of salt getting in there too. Best to clean all the sealer off, bring all the oxidation off the metal and recoat. Replacing petrol tanks is a job best done by others (that have already gone to hell).Originally Posted by Jehu

I'll have to take a picture and look at it closer but it looked from what i remember to be rusting on the outside maybe from the hot muffler causing cold gasoline to create condensation on the outside of the tank, the other side is fine.It'd be nice to be able to remediate the decay before i explode taking a fast right turn.

it's metal and rusts out a few different ways, e34s are one of the last metal tank bmws if not the last
