Ingo,
Sounds like you'll have the external steel pretty well prepped so the automotive system should do a fine job for you.
For the nooks and crannies on the inside and all the cavities that will not get a white metal blast but will get closed up never to see the light of day again, then I would highly recommend ZR for all that steel.
2000 hour salt spray numbers, single package system, no isocyanates, goes on like paint did 20 years ago and it's not $150 a gallon......
