Thanks foot: Haven't pulled the front fender flares yet. Hopefully this weekend.

I like idea of panel adhesive for rear wheel wells / arches. With my novice welding skills, this sounds like best option.

I've looked between bed sides and it's pretty good in there (minus the arch where water and dirt collected behind flare). Once the patches arrive I'm going to inspect and cut more out. Hopefully I will be able to reach solid, un-rusted metal.
