Dottie Rae's rotten Trunk Gutter

Have you done much body work HemiSSDart?

I ask in regard to rustproofing. My plan is to clean up wherever rust is visible (bottom also) and then spay with 3M Weld-Thru primer. I am curious about using Rusr-Mort or another Rust Converter product before 2K Epoxy primer and topcoat.

actually, after rust treatment/removal I was planning to use POR-15 on the interior floorpan/wheel wells and the bottom too. The POR requires topcoat almost immediately if I understand correctly.
