Plastic body filler (Bondo is a brand name) might not be the best idea on a surface that could flex slightly in use. However, before anything else, they should be sand blasted and given a phosphate coating using something like Ospho. If you need to fill in the ridges, I think that Fiberglas would be a better choice. It’s harder to work with and you need good protection (high quality mask and goggles) but it will give a far better and longer lasting job once done. I know that body filler can have a strengthening in mesh in it but even so it’s just too brittle for this sort of thing.
