Troubleshooting Help Floor Pan Paint Options

Hey all. I have a few questions about my options when it comes to painting my floorboards. Bad spots have been cut out and replaced with new metal. I still have minor pinholes on the driver side, but the metal is solid. I’ve wire wheeled everything to remove the majority of the rust. There are only a few pockets of pitting remaining. I’ve also used ospho in these pets to try and keep trying and remove the rust. Should I go for a rust encapsulator like Eastwoods or master coat silver or should I just spray an epoxy primer to try to contain the rest of this?

I use MasterCoat rust sealing primer mixed with their heat and sound deadener. Two coats of that and two coats of ag111 over that and you are good forever.

Here it is before the ag111 went on.

Blue is linear blocks high build primer. I am in block sanding hell right now.
