How to prevent rust on stripped metal for a long time?

[Guycali]

I've always had a question about that. As for most of us, we only have time to work on the Z on weekends. That means, we'd need to protect the bare metal from rusting after we strip off the paint, tar, whatever for months or years before completing the restoration. I know Metal Ready from POR-15 etches the metal and coats it with a layer of zinc phosphate. But how long does it last to offer good enough protection against rust? Having the shell primered for a long time isn't that great of an idea either since the primer is porous and moisture can get in to cause rust as well. Is there any other good way to keep it at bare metal while one completes what is necessary to go into the chassis and body, when we know for sure that the entire body work can last for a long time?

The pic below shows a full weld-in cage and seems like the Z has been stripped out of its paint completely. I wonder how long has it been sitting naked?

That really is a good question! I've often wondered myself how long is a reasonable time for a primed car to sit before painting. You are right the primer will soak up moisture if left for too long. I imagine where you live plays a big part in this also. Humidity, as in Florida, is a major problem even if the car is in a garage. And if you live in a dry climate and keep it in a garage I imagine you have plenty of time before protection is required. If anyone has an answer I'd like to know. Is there a primer/ sealer that would work? I think I saw this somewhere on this site before.

We have a product over here called Kephos, it's a clear film that you wipe over the bare metal and it is supposed to keep it from rusting for 2 years, I will look at the label tonight and see if I can get any more details.
