Floor board prep
I found moisture and mild rust on the floor boards of my 73 F100 when I ripped out the vinyl floor covering. I plan to use that roll on that bed liner material to cover it. To deal with the rust can I simply sand out the spots and primer it, or is there a better way? I want to get all the floor maintenence stuff out of the way before I move on to the instructions specific to the bed liner stuff.

Just a note, in my experience the bed liner is not the best way to protect your floor boards. We had a work truck rot out big time from this method. Seems that moisture can get behind it sometimes. Anyway what you really need to do is eliminate the rust, meaning cut it out if it is that bad or wire wheel it then treat it with an etch or rust encapsulating paint. Then you can do what you want to it.
I'd wire wheel it, then acid etch, gets into all of the nooks and crannies and eats/converts the rust, leaving a nice smooth zinc phosphorous surface perfect for paint adhesion. Paint it with Rust bullet or Eastwoods rust encapsulating paint and top coat. Good luck. Take some pictures through your process and post them.

Personally I prefer the sand blasting process. Because it removes nearly every particale of rust and creates a very porus surface for paint/primer to adhere. Depending on your time and budget.
Even tho Por-15 only recomends wire brushing and proper surface prep with metal ready. One draw back to the Por-15 is that it is quite expensive and adhears rock hard, its near impossible to remove from skin, clothes, and tools.
I applied bedliner to my floor ontop of the Por-15 hopfully it holds up well and I dont have any problems. I can also see where the bedliner can cause a problem of trapping in moisture.

Thanks for the info, I may go the POR-15 route afterall. I got the rest of the vinyl out and most of the floor looks good, nothing a wire brush won't take of, however, I found a dime sized rust hole on both sides at exactly the same spot, within an inch of the door under when the weather stripping was hiding it. Looks like I'll be doing some minor body work first. If there is a bright spot to the holes, I sat at a low spot where any water drained right out and didnt extend the damage elsewhere.

Here's what i'd suggest... I would do the rust repair/removal, coat with some type of rust encapsulating paint. That takes care of the rust and the potential to come back. Next i'd get some sound dampening material and lay that down. Next i'd either carpet or put the rubber mat back.
The rhino liner will be loud, really loud, at least with the rubber mat you get some sound dampening and heat disipation. i worry about the liners, if the prep is not right or they aren't applied right they can allow moisture throug or even crack.
The metal in the bed is much thicker and has less give, if you throw a tool in the bed there will not be much flex upon impact, floor board of your truck is a different story. Thinner metal, and you are getting in and out all of the time a little flex and you begin to weaken the lining. Again this is what happened to one of our trucks. Just my $.02
