Rust proofing rear wheel wells, I have questions Options

[john77]

While I have the arches cut for the flares I figured it was a good time to strip the wheel wells to bare metal, fix anything I find, and reseal them. I’ve completed the fronts, but just started stripping the rears yesterday and have some questions.

What’s the best way to reseal/rustproof the section above the rear light housing?

I’ve stripped a lot of 1970’s German rubberized seam sealer in my time but was surprises to find that section was filled with what looks like some kind of expanding foam. The area is obviously a crud catcher, so I’m wondering the best way to seal it back up? Seam sealer? Or is there some other product I should fill the void where the foam was first?

The other section I’m wondering about is in the front of the well where the sail panel meets the quarter panel (the L shaped section coming down into the wheel well).

It seems odd that this was so open - is it supposed to be covered in seam sealer?

I’ve scraped some debris out of it, but would love some advice on what to do with it when I paint/reseal everything.

John77, if you'd like I can send you a paper template of each wheel well as a start point. With flares all liners will be a little different. I'm also going to add a rubber cowl seal around the edges to keep all water out. Mark
