To swap frames or not?

I know what you mean, there are several around here and talking to the owners they have noticed what 1 winter does to their beautiful, rust free trucks. Everything that is remotely unprotected has surface rust in 1 winter. when left alone, 2 or 3 winters and the cancer has spread to the point where sheet metal needs to be cut and new sections welded in to get rid of it. Same issues with the frame. From what I've see out here things that have more holes and allow water, dirt, air to pass through them have a better chance (once coated with something to cover the metal) then things that are enclosed. I look at a lot of domestic vehicle - I know different steel, etc. but I have a 39 Hudson (in need of desparate frame off resto) that has a frame that is only a "c" channel. This thing is more solid then mine right now, and it's 3 times as old as my truck! Domestic steel could not have been that durable.

The thing with most of these JDMs is the seams. The canadian ones already show the rust. The japanese ones are just about too. The JDMs are still 20 plus years old. The rust is there, but small and hasn't grown much.

I suggest anyone who imports one gets it krown oiled/rust check...etc every year.

Flood all the areas with oil.

I agree, it is definitely a good preventative measure to assist with a longer lifespan of the frame. It is a bit of a PIA to work on the truck when the frame is covered in oil, but then again it is a Diesel, so you already have that issue in other parts of the truck.
Well, regardless of all the valuable info here, we did end up sidetracking from one of the original questions, what has been used to coat or treat a frame to make it "rust proof" and if possible what have been the results over time.

I am going to POr-15 my frame. Within a short time.

I will then after coat if with LPS 3. Inside and out.
