one of these days i'm gonna need to replace a portion of the rocker panel on my Corrado. I got the required section cut off a non rusty one and sooner or later i'll get to welding it in.

the question is: the inside has some rust protection that will inevitably get burned off when welding together. how would one go about ensuring the welded section doesn't rust out in a year due to zero protection on the inside?

the goal here is to do it properly so the car lasts another 20 years....
