So I just got my 4runner, and I'm thinking ahead and wondering about undercoating to prevent, or at least slow down rust. It already has a bit, mostly surface around the welds.

I searched a bit, but was wondering what the best way to go about this. POR-15 is expensive, but sounds like its worth it.

Ive never really done anything like this before, what parts do you paint, can you do it without taking the whole car apart? I have a driveway and jackstands for tools.

Theres the picture of the worst of the rust.

Could I just paint over it, what prep work is involved? Is it worth the time/effort?

How much POR-15 or better product would I need to coat the whole, or at least better part of the underside?

Thanks for putting up with the questions?
