FWIW this was my procedure. Removed drain/screen, sanded rust/corrosion, sprayed it with Ospho, used two part resin (for auto/boat fiberglass repair) to fill damage, finish sand, apply epoxy paint over repair. You absolutely have to get it clean before covering it with paint. About 20 years later the repair still looks new.

Thanks for the info!
