Rear fender foam, replace or other? Options

[bbrock]

I know this has been discussed before but wonder what current consensus it. I stripped out the seam sealer and urethane foam that fills the cavity near the tail lights at the rear of the quarter panels yesterday. Happy to say everything looks pristine inside. That cavity looks like a serious mud catcher and given that there are 3 miles of dirt road between my house and pavement, I'm not comfortable leaving it open. I'm thinking of filling it with Evercoat Sealant Foam after epoxy primer and then sealing like the factory did. Any better options?

Prime & paint before anything, & IMHO Zinc Rich Primer to serve as sacrificial metal with epoxy primer over - all materials of top quality, e.g.: Dupont, PPG, Glasurit, Sekkunds, etc. (Wurth & Eastwood make good zinc primer).

Then whatever Eastwood or other top brand cavity filler/sealer, undercoating, etc. - or maybe the 914Rubber fender liners (I'm not familiar with those).

Not an expert but painting epoxy over the zinc primer is a waste of the zinc primer.
The idea of the zinc primer is that it corrodes instead of the iron but it must be in contact with the air (oxigen) to do that.
