Hello all. I'm in my very long process of fixing the rip in my frame that is front of the rear boxed frame area under the passenger door. The story is people may lift the car wrong or get hung up on cement creating a rip in the frame etc. Anyway, I've drilled my rip end to stop the rip, completely cleaned out the rip creating a space for full weld pool. welded the cleaned rip. Then I created a fish plate. I'm about to prime the pictured frame section/spot with SEM'S "weld through primer" . My question is my fish plate is going to cover the factory hole in the frame. What's it for? And, I'm covering it up because I feel like replicating a hole in the plate to have it there is only another place for water to get in between the fishplate and the frame. I don't think that's good. I'm planning on sealing the outside frame side between body with a putty knife and some sort of material spread to finalizing sealing. There is not much space there if you understand my spot. it's somewhere just under a 1/4 inch on my car. Am I having the correct idea welding the fishplate over the hole? If not, what's a better reason to leave the hole there collecting rain water between the plate and frame to have this "original" hole there? Notes/info: Ive went past the hole with the fish plate because bringing it up to the hole seems a weaker repair to me. Do I really need the hole? Thanks always.
