Sarge's rattle-can rebuild

[68Timber]

Question for anyone with experience or learned opinion... My drivers side inner rocker has some rust that I've cut out back to good metal. I'm going to use panel bond adhesive to patch over the area. I want to use POR to treat the area first but I'm concerned about the panel bond instructions that say to use on bare metal. Do I need to be concerned about panel bond not adhering to POR?

Also, apparently the seat bases changed more times than I'm aware of. I've got two sets of front bases from a 79 that don't fit this 85. I know they changed again in the later 80's K5's. If anyone knows what years I need to shop from I'd appreciate it, I need to put an ad up in the classified area and need to know what to ask for.
