So do you think it warrants an entire floor pan to get rid of rust in this case?
I agree with you on wanting to do it right though, but as mentioned I've read where people have had large success on panels with rust treatments/encapsulators and just thought that with that things might be okay which is why that was my initial thoughts as I have the abilities to be able to do that whereas Id have to get the welding machine up to par and make sure I could use it or pay someone. Before any of this was applied Id for sure use a wire wheel, etc to get down as far to bare metal as I could.
I've also seen where companies like por15 make a por putty and other kits/products for things such as small holes which is another thing that peaked my interest. I do know that on one fender I'll have to get a patch panel welded I believe.
I don't see any places in that picture that require a new replacement panel but that's just my opinion
