Do I need to Sandblast?..and other paint opinion questions

[b-mac]

I am currently working on the inside of the cab of a '49 on an s10.

I want to begin to get pieces in primer as I go, but I wanted to pick you guys brains and see which direction to head?
The outside of this truck will likely stay patina, for a while at least, but I want to get the interior looking sharp.

So...Do I need to sandblast the inside of the cab? What are your thoughts/methods on other types of rust removal? Converters? Sand and wire brush what I can, and hit the rest with Fast-Etch or something? Self etching primer in a rattle can? Is there a rattle can primer that is high quality enough to last?

Maybe you can provide your good-better-best method. Without a trailer, taking it to get sandblasted is difficult, but not impossible. But I would like to avoid it if others have had success with other methods.

I mentioned I'm working on the interior, but the same questions could be asked for the frame and chassis.

Thanks in advance for your responses.
